SK Telecom and Thales Trial Post-quantum Cryptography to Enhance Users’ Protection on 5G SA Network

Korean telco SK Telecom and digital security firm Thales have tested quantum-resistant cryptography based on a 5G standalone (5G SA) network.  The trial is focused on encrypting and decrypting identity data on a 5G network to protect user privacy from future quantum threats. It was performed using Thales 5G Post Quantum Cryptography (PQC) SIM cards and a trial 5G standalone network environment from SKT.  The test involved cryptographic algorithms designed to resist attacks from quantum computers, as well as ‘classical’ computers.

The end user identity on the 5G SA network is concealed and secured on the device side via the 5G SIM card. The security mechanisms involve cryptographic algorithms designed to resist attacks from future quantum computers, providing a level of security that is considered robust in the post-quantum era.

The U.S. National Institute of Standards and Technology (NIST) has been leading an initiative to standardize post-quantum cryptographic algorithms, and SKT and Thales have used the Crystals-Kyber one for this successful real condition trial. These post-quantum secure algorithms are being developed to withstand attacks from both classical and quantum computers.

“This collaboration between SKT and Thales highlights our commitment to staying ahead of the curve in terms of cybersecurity and ensuring the safety of our customers’ data. PQC provides enhanced security through the use of cryptographic algorithms that are thought to be secure against quantum computer attacks. Going forward, we will combine PQC SIM with our additional Quantum expertise to achieve end-to-end quantum-safe communications,” said Yu Takki, Vice President and Head of Infra Technology Office of SKT.

“As quantum computers have the potential to break certain existing cryptographic algorithms, there is an emerging need to transition to cryptographic algorithms believed to be secure against quantum attacks. For 5G networks, Thales started to invest on cryptographic algorithms that are quantum-resistant to enhance continued communications security and privacy for users,” said Eva Rudin, SVP Mobile Connectivity & Solutions at Thales.

As quantum computing gets more reliable and presumably starts getting used more widely in the future, this type of security is going to become increasingly important. Nokia recently announced it had completed a proof of concept trial alongside Greek research consortium HellasQCI, demonstrating what it calls quantum-safe connectivity infrastructure.


Separately, SK Broadband, an internet and paid TV service affiliate of SK Telecom, launched additional personalized internet protocol television (IPTV) services utilizing AI technology to enhance its competitiveness in the country’s paid TV market, the company said Wednesday.

ABI Research: Expansion of 5G SA Core Networks key to 5G subscription growth

The number of 5G subscriptions will surge from 934 million in 2022 to 3.1 billion in 2027 -a Compound Annual Growth Rate (CAGR) of 27% –  according to a study from ABI Research.  Further, 5G traffic is forecast to increase from 293 Exabytes (EB) in 2022 to 2,515 EB in 2027, at a CAGR of 54%.

ABI’s forecast is largely based on an increase in 5G Core (5GC)  networks. To date, more than 35 5GC networks are operating in 5G standalone (SA) mode. 5GC is expected to lead to a growth in devices connected to the network and the traffic routed through it.

“5GC holds potential for operators to monetize further existing cellular connectivity for traditional mobile broadband (MBB) use cases but also offers scope for operators to expand cellular capabilities in new domains. Additionally, 5GC also offers innovation potential for committed telcos to establish new operating models for growth outside of the consumer domain,” explains Don Alusha, Senior Analyst, 5G Core and Edge Networks, at ABI Research.

5GC presents Communications Service Providers (CSPs) with a fluid and dynamic landscape. In this landscape, there is no static offering (requirements constantly change), no uniform offering (one shoe does not fit all), and no singular endpoint (one terminal with multiple applications). 5GC guides the industry into edge deployments and topologies. CSPs step out of the four walls of either their virtual Data Center (DC) or physical DC to place network functionality and compute as close to their customers as possible. This constitutes decentralization, a horizontal spread of network assets and technology estate that calls for a ‘spread’ in the operating model.

The shift from a centralized business (e.g. with 4G EPC) to a decentralized business (5G SA core network) stands to be a significant trend in the coming years for the telecoms industry. Against that backdrop, the market will demand that CSPs learn to drive value bottom-up. “What customers need” is the starting point for companies like AT&T, BT, Deutsche Telekom, Orange, and Vodafone. In other words, in this emerging landscape, there will be enterprise-specific, value-based, and niche engagements where the business strategy sets the technology agenda. So, it is rational to conclude that a “bottom-up” approach may be required to deliver unique value and expand business scope. That said, CSPs may be better equipped to drive sustained value creation if they learn to build their value proposition, starting from enterprise and industrial edge and extending to core networks.

“A 5G cloud packet core can potentially unlock new transactions that supplement existing volume-centered modus operandi with a local, bottom-up value play for discrete engagements. But the power of a bottom-up model is not enough. To monetize a 5G cloud packet core at scale, some of the existing top-down intelligence is needed too. Learning how to operate in this hybrid top-down and the emerging bottom-up, horizontally stratified ecosystem is a journey for NTT DocomoRakuten MobileSingtelSoftbank, and Telstra, among other CSPs. In the impending cellular market, an effective and efficient operating model must contain both control and lack of control, both centralization and decentralization and a hybrid of bottom-up plus some of the ‘standard’ top-down intelligence. The idea is that CSPs’ operating model should flexibly fit and change in line with new growing market requirements, or new growth forays may hit a roadblock,” Alusha concludes.

Editor’s Note:

It’s critically important to understand that the 3GPP defined 5G core network protocols and network interfaces  enable the entire mobile system.  Those include call and session control, mobility management, service provisioning, etc.   Moreover, the 3GPP defined 5G features can ONLY be realized with a 5G SA core network.  Those include: Network Automation, Network Function Virtualization, 5G Security, Network Slicing, Edge Computing (MEC), Policy Control, Network Data Analytics, etc

Figure 1: Overview of the 5G system

The 5GC architecture relies on a “Service-Based Architecture” (SBA) framework, where the architecture elements are defined in terms of “Network Functions” (NFs) rather than by “traditional” Network Entities. Via interfaces of a common framework, any given NF offers its services to all the other authorized NFs and/or to any “consumers” that are permitted to make use of these provided services. Such an SBA approach offers modularity and reusability.

Figure 2: 5G SA Core Network Architecture

The 5G SA architecture can be seen as the “full 5G deployment,” not needing any part of a 4G network to operate.

Finally, 3GPP has not liased their 5G system architecture specifications to ITU-T so there are no ITU-T standards for 5G SA Core Network or any other 5G non-radio specification.  Instead, 3GPP sends their specs to ETSI which rubber stamps them as “ETSI standards.”

5G is a big letdown and took a “back seat” at CES 2023; U.S. national spectrum policy in the works

It’s Not Just You: 5G Is a Big Letdown,” is the title of a Wall Street Journal on-line article published today (January 11, 2023).  Author Joanna Stern writes:

I turned off Verizon’s red down pointing triangle 5G on my iPhone—and barely noticed a difference. The 4G LTE performance and coverage felt just about the same.

Three years since the U.S. cellular carriers lit up their next-generation networks and promised to change the game, the game hasn’t changed. And if you’re among the millions of Americans who recently upgraded, you probably already know that. In 2022, 61% of U.S. cellular customers accessed 5G networks, according to Global Wireless Solutions, a network testing and research company.

On Verizon’s Ultra Wideband network, I got 500 Mbps down. But I didn’t notice a difference when streaming Netflix, watching TikTok, loading websites or sending messages. You don’t need a fire hose to extinguish a candle.

Where you might see a difference is during commuting hours and other times of heavy congestion, Chetan Sharma, a telecom-industry analyst, told me. A Verizon spokesman said that 5G’s higher data capacity helps at concerts, sporting events and other crowded areas where everyone is trying to download or upload photos or videos.

“As cars, smart home standards, and so many screens took center stage at this year’s [CES] show, 5G took a back seat,” concludes  a Verge article titled, “Where was 5G at CES?” “After years of hype, 5G was seemingly a no-show at CES 2023.”  The Verge article continues knocking 5G (and for good reason):

For starters, we’re all sick of hearing about it. And CES has a unique way of rallying around a technology one year and then leaving it for dead the next.

And there was always a time limit on 5G’s newsworthiness — at a certain point, when it becomes the prevailing wireless technology, it’s not going to be “5G the new thing;” it’ll just be “the internet you use when you’re not on Wi-Fi.”

More than any of the above, the time has passed where wireless CEOs feel they need to sell 5G to the general public (and, of course, their shareholders). It’s not a niche new service anymore; it’s the default option (in the U.S. at least). Basically every new phone sold on their shelves is 5G compatible, and mid-band 5G finally exists on all major carriers in large parts of the US. The next time you walk into a wireless store to buy a new phone or sign up for a new service, you’ll have a very hard time leaving without a 5G device and plan, regardless of whether you really wanted them.

So now we have 5G phones in our hands, 5G networks are here, and… not much has changed. Maybe web pages load a little faster — hardly robot surgery. What gives? The thing is, rolling out 5G is a long ongoing process. The hype made it seem like all the good stuff was just around the corner, but truthfully, it was (and still is) years and years away.

So yes, you may have a 5G icon on your phone, but the most transformative aspects of 5G are supposedly still in the works. That’s a tough message to sell in a flashy keynote, especially when everyone in the room has access to the technology you’re talking about.


The IEEE Techblog in general, and this author in particular, have been pounding the table for years that 5G would be a colossal tech train wreck for these reasons:

1.  3GPP Release 16 URLLC in the RAN spec and performance testing have not been completed.  Hence the URLLC in 3GPP Release 15 and ITU M.2150 recommendation do not meet the critically important URLLC ITU M.2410 performance requirements for ultra high reliability or ultra low latency. Here is the latest status of URLLC in the RAN in the 3GPP Release 16 specification as of 6 January 2023:

–Physical Layer Enhancements for NR Ultra-Reliable and Low Latency Communication (URLLC) NR_L1enh_URLLC 1 Rel-16 R1 6/15/2018 12/22/2022 96% complete RP-19158

–UE Conformance Test Aspects – Physical Layer Enhancements for NR URLLC NR_L1enh_URLLC-UEConTest 2 Rel-16 R5 12/14/2020 12/22/2022 90% complete RP-202566 RP-221485

2.  There is no implementation standard for 5G SA Core network– only 3GPP reference architecture specs which list alternative implementation schemes, most of which are “cloud native.”  That resulted in a lot of telco confusion that delayed the roll out of 5G SA networks such that most 5G deployed today is NSA which uses 4G LTE core network and functions.  Dell’Oro Group’s Dave Bolan wrote in a white paper:

The 5G Core is the key to monetizing the 5G SA network bringing MNOs (Mobile Network Operators) into the modern cloud era, allowing the MNO to (1) offer new services quickly with Cloud-Native Network Functions, (2) add Network Slices on demand for mobile private networks, and (3) address latency-sensitive applications with MEC. These new opportunities cannot be addressed by 4G or 5G NSA networks, and the sooner an MNO embraces 5G SA networking, the closer it will be to reaping new revenue streams.

3.  ALL of the 3GPP defined 5G functions and features, require 5G SA Core network.  Those 5G functions include 5G security, network slicing, and automation/virtualization.  MEC also needs a 5G SA Core network to work efficiently with a 5G RAN.  There are relatively few 5G SA Core networks deployed and for those that are, there are few of the highly touted 5G functions available, e.g. T-Mobile is a case in point.

4.  There is no standard for roaming between 5G networks, especially not when there are different versions of 5G SA core networks- each requiring a different software download for 5G endpoint devices.  Hence, 5G is not truly mobile in the sense of portability.  5G is probably best used for FWA or local M2M/IoT communications where there are no roaming requirements.

5.  There is no standard for 5G Frequency Arrangements (ITU M.1036 revision 6) which are critically important for all the mmWave frequencies specified at WRC 19 for 5G, but frequency arrangements not yet agreed upon by ITU-R WP 5D.

6.  5G base station and endpoint device power consumption is very high, especially for the mmWave frequencies which deliver the fastest 5G speeds.


5G in India:

Mike Dano of Light Reading writes that the U.S. is working on a national spectrum policy, presumably for 5G (and later) 6G.

The White House is working through the NTIA to develop a national spectrum strategy that would cover 5G, 6G and other spectrum users.

According to FierceWireless, National Telecommunications and Information Administration (NTIA) chief Alan Davidson said that work would continue throughout this year.  Speaking at last week’s CES conference in Las Vegas, Davidson reminded the audience that the NTIA manages federal spectrum use and serves as the President’s advisor on spectrum policy.  That  means that the NTIA works together with the FCC to manage spectrum when a federal user is involved. From a practical perspective, the Department of Defense has historically held a lot of valuable spectrum for national security use, making the DoD an incumbent user in many spectrum bands.

In 2023 NTIA will be working with federal agency partners to develop a national spectrum strategy, which will provide a long-term plan to meet both commercial and federal spectrum needs.


Officials from the National Oceanic and Atmospheric Administration (NOAA) said they’re taking stock of the agency’s spectrum usage in order to potentially release some for commercial uses, according to SpaceNews.  “It is an ongoing challenge.  We expect to have to fight for maintenance of spectrum. But at the same time, we realize we’re not going to win every fight,” said Steve Volz, NOAA Satellite and Information Service assistant administrator on January 11th at the American Meteorological Society meeting.

Spectrum for 5G and 6G is a critical national policy topic:

“Continuing to meet increasing consumer demand and expectations, ensure continued growth of the US economy, bridge the digital divide, and facilitate global leadership on next-generation technologies requires sufficient spectrum resources,” wrote the CTIA, the US wireless industry’s main trade association. “Accordingly, it is imperative that the commission continually replenish its pipeline of spectrum allocated for commercial mobile and fixed broadband services.”

“America needs a national strategy to make sure there is enough spectrum to build out 5G networks and not fall behind China,” wrote Mike Rogers, a former Congressional representative from Michigan who authored a report critical of China’s Huawei, in The Hill.

Joel Thayer, of the Digital Progress Institute, agreed. “If we cannot get our act together and follow an all-of-the-above spectrum strategy, we cede the race to 5G and even 6G to China. Full stop,” he wrote in The Hill.

Such arguments strongly echo the “race to 5G” rhetoric that was ubiquitous in policy circles in the early days of 5G.

Another Opinion: 5G Fails to Deliver on Promises and Potential


For many years now, this author has repeatedly stated that 5G would be the biggest train wreck in all of tech history. That is still the case.  It’s primarily due to the lack of ITU standards (really only one- ITU M.2150) and 5G core network implementation specs (vs 5G network architecture) from 3GPP.

We’ve noted that the few 5G SA core networks deployed are all different with no interoperability or roaming between networks.  I can’t emphasize enough that ALL 3GPP defined 5G functions and features (including security and network slicing) require a 5G SA core network.  Yet most of the deployed 5G networks are NSA which use a 4G infrastructure for everything other than the RAN.

It also must be emphasized that the 5G URLLC Physical layer specified in ITU-R M.2150 does not meet the performance requirements in ITU-R M.2410 as the URLLC spec is based on 3GPP Release 15.  Astonishingly, the 3GPP Release 16 work item “URLLC in the RAN” has yet to be completed, despite Release 16 being “frozen” in June 2020 (2 1/2 years ago).  The official name of that Release 16 work item is “Physical Layer Enhancements for NR Ultra-Reliable and Low Latency Communication (URLLC)” with the latest spec version dated June 23, 2022. That work item is based on the outcome of the study items resulting in TR 38.824 and TR 38.825. It specifies PDCCH enhancements, UCI enhancements, PUSCH enhancements, enhanced inter UE TX prioritization/multiplexing and enhanced UL configured grant transmission.

Finally, revision 6 of ITU-R recommendation M.1036 on terrestrial 5G frequency arrangements (especially for mmWave), still has not been agreed upon by ITU-R WP5D.  That has resulted in a “frequency free for all,” where each country is defining their own set of 5G mmWave frequencies which inhibits 5G end point device interoperability.


In an article titled, 5G Market Growth, Mohamad Hashisho provides his view of why 5G has not lived up to its promise and potential.

Standalone 5G Is Yet to Breakout:

5G market growth still needs to feel as imposing as many imagined it. A technology created to replace previous generations still relies on their infrastructure. Standalone (SA) 5G is unrestricted by the limits of the prior generation of telecommunications technology because it does not rely on the already-existing 4G infrastructure. As a result, it can deliver the fast speeds and low latency that 5G networks have consistently promised. Clearly, standalone(SA) 5G is the way to go, so why do we not see effective implementation and marketing for it?

The numerous challenges businesses encounter while using SA are alluded to in the various telco comments about device availability, carrier aggregation, and infrastructure upgrades. The 5G New Radio system is connected to the current 4G core, the network’s command center, with older NSA. As its name suggests, SA sweeps this crutch aside and substitutes a new 5G core. But operators face several difficulties when they push it out, according to Brown. The first is the challenge of creating “cloud-native” systems, as they are known in the industry. Most operators now want to fully utilize containers, microservices, and other Internet-world technologies rather than simply virtualizing their networks. With these, networks risk being less efficient and easier to automate, and new services may take longer to launch. But the transition is proving to be challenging.

Overpromising, Yet to Deliver:

5G came out of the corner swinging. Huge promises were thrown around whenever the subject of 5g was discussed. It has been a while since 5G came to fruition, yet its market growth remain humble. Some might say that the bark was way more extensive than the bite. While some of these promises were delivered, they weren’t as grand as the ones yet to happen.

Speed was one of the main promises of 5G. And while some argue that this promise is fulfilled, others might say otherwise. Speeds are yet to reach speeds that can eclipse those of 4G. It is not only about speeds, though. It is about the availability of it. The high-speed services of 5G networks are only available in some places. Its been years and many regions are yet to receive proper 5G services. Simply put, a large portion of the dissatisfaction surrounding 5G can be attributed to the failure to fully deploy the infrastructure and the development of applications that fully utilize 5G.

5G of Tomorrow Struggles With Its Today:

5G is, without a doubt, the way to go for the future, but does its present state reflect that? Maybe. That is the issue. Years into its adoption, the answer should be decisive. Telcos might see potential in the maybes and work based on tomorrow’s potential. Consumers won’t be as patient. The consumers need the promised services now. You need to keep your customer base around with promises of the future. Especially when 4G LTE did the job well, really well.

Moreover, some areas in the US, not in struggling countries, have speeds slower than 4G LTE. Some 5G phones struggle to do the minimum tasks. Phones have to stick to specific chips capable of 5G support. But it is not about the small scale. Let’s think big, going back to the big promises 5G made. Smart cities, big-scale internet activities happening in real-time. IoT integration everywhere, controlling drones and robots from across the world. Automated cars as well, 5G was promised to deliver on all that, today and not tomorrow, but here we are.

Finally, the marketing was hit and miss, more miss, to be frank. Most consumers pay more to be 5G ready, while 5G still needs to be truly prepared. It’s hard to keep people interested when 4G is doing great. The only thing that the people needed was consistency, and sadly 5G is less consistent than some would hope.

Concluding Thoughts:

Lastly, innovation waits for none. This even includes 5G and 5G market growth. There are talks, even more than talks, about 6G. China is pushing for 6G supremacy, while Nokia and japan are starting the conversation about 7G. A major oversight that 5G missed was range. 5 G does great over small distances.

When the promises were massive in scale and global, you practically shot yourself in the foot. Time is running out for 5G, or is it pressuring 5G to live up to its potential?

Understanding security threats for telco edge and private 5G networks

Author: Adil Baghir  (edited by Alan J Weissberger)


Telcos and enterprises realize the need to move toward the network edge to deploy cloud-like solutions to leverage the massive advances in transmission offered by 5G. Benefits such as speed, low latency, and capacity will drive major transformation for telcos and enterprises, opening new revenue opportunities from new business models.  We’ll examine several 5G deployment scenarios and security threats in this article.

Telcos and enterprises are exploring new use cases by deploying edge clouds and bringing content and applications closer to the users and billions of IoT devices to meet the low-latency requirements. The Ericsson 2022 Mobility Report forecasts that over 30 billion Internet of Things (IoT) devices will be connected by 2027.

The 5G core network functions could be deployed as a microservice in a private data centre of the communications service provider (CSP) and enterprise network or in a public cloud (like AT&T-Microsoft Azure and Dish Network-Amazon AWS).

The shift to the edge and deploying telco cloud edge services and enterprise hybrid private 5G networks introduce new security threats associated with the 5G and edge deployment.

Even though there are security risks with 3G/4G, these risks are mainly associated with external attacks. However, with 5G/MEC/IoT architecture, these risks become more serious. 5G core and edge sites can be attacked from the internal network in an “inside-to-outside” approach. Considering that 5G provides high-speed internet broadband, connecting a massive number of consumer and IoT devices, this can be viewed as a new point of attack for the 5G cloud edge architecture.

Such massive transformation forces telcos and enterprises are deploying cloud edge and private 5G services to rethink their security and network protection. There are many challenges in how telcos and enterprises deploy security solutions today as they cannot provide integrated 5G core and security solutions to adapt with cloud-edge use cases. For example, moving to the edge will require a low footprint, automation, scaling and simplified lifecycle management (LCM). Given the increase in the number of edge sites deployed, it will be very complex to manage and scale different security solutions manually. The typical deployments of security solutions are not optimised for distributed and cloud-edge architectures.

The impact of security compromise on an operator or enterprise edge network could be massive because edge sites usually have less capacity than core sites and host mission-critical applications to accommodate low latency requirements, including IoT use cases. For example, a 10/20G volumetric DDoS attack could have a major impact on the network availability and low-latency requirements, and it would lead to a critical service interruption and result in brand damage.

The shift to cloud and edge for telcos and enterprises is an evolved approach to deploying and delivering services and solutions, and introducing a more dynamic environment. The security measures in place today are not aligned with the cloud-edge requirements for the footprint for physical security solutions, increasing number of edge sites, cloud-native strategy and other required capabilities to improve TCO.

DDoS-based IoT Botnet

Most IoT devices have limited computing resources to provide security functionality and typically are not securely coded. MOZI is an example of a DDoS-focused IoT botnet that utilises a large set of remote code executions (RCEs) to leverage common vulnerabilities and exposures (CVEs) in IoT devices for infection. These devices include network gateways, CCTVs, DVRs, etc. Once the IoT device is successfully infected, the botnet uses protocols/apps, such as TCP/UDP/HTTP, to send and receive configuration updates and attack commands. Eventually, the infected IoT nodes begin generating attack traffic, leading to a massive and sudden spike in UDP traffic going back and forth with peer-to-peer networks. Such volumetric attacks from compromised IoT devices will make it very challenging to guarantee a level of service and maintain low-latency requirements.

Even though it’s always recommended to keep the IoT devices running the latest firmware with all the necessary security patches applied. However, we can’t rely entirely on securing or updating IoT devices. Therefore the network should also be equipped with modern security solutions like DDoS baselining techniques to see anomalous behaviour versus historical norms, and AI/ML techniques, for detection and zero-day attack prevention.

Mobile Edge Cloud and Private 5G Requires New Security Approaches

Security for mobile cloud edge and enterprise hybrid private 5G must be measured carefully to align with the new and increasing security threats. This requires securing the mobile core infrastructure and modern network protection to deliver mission-critical applications while maintaining low latency requirements. Ultimately, this will help telcos and enterprises achieve their desired business outcomes.

In addition, the security implementation for telcos should consider security-as-a-service so that operators may offer secure IoT services leveraging network slicing and provide the flexibility for end customers to manage their security policies with complete network isolation. This requires security integration with the 5G ecosystems to ensure subscriber and device awareness for more agile security control.

Enterprises that deploy private 5G networks may lack the telco experience and knowledge to secure that mobile infrastructure. They might rely entirely on the MNO or their mobile network equipment providers (NEPs) to ensure the infrastructure is fully secured and protected. However, enterprises must extend their network and IT security standards and take all the necessary considerations when they move their critical systems and applications to the edge.

Although 5G comes with embedded security standards, it also introduces potential security risks associated with the deployment model and communications systems. In this post, I have focused on one of the security risks associated with 5G deployment: a DDoS-based IoT botnet. In Part II, I will cover other potential security areas:

  • 5G deployment in Hyperscale Cloud Providers (HCP)
  • HTTP/2 and exposure of API
  • Inert-PLMN

CTIA Announces 5G Security Test Bed for Commercial 5G Networks

CTIA today announced the launch of its 5G Security Test Bed (STB), a security testing and validation initiative dedicated to commercial 5G networks. CTIA created the STB in partnership with organizations across wireless, tech, and academia to test 5G security recommendations across real-world conditions using commercial-grade equipment and facilities.

The 5G Security Test Bed’s founding members—AT&T, Ericsson, T-Mobile, UScellular, MITRE, and the University of Maryland (UMD)—contribute invaluable industry expertise that strengthens the STB’s ability to enhance the wireless security ecosystem and ensure strong protections on 5G networks.

There are no ITU standards for 5G security, which requires a 5G SA Core network. Rather, there are 3GPP 5G Security technical specifications (TS 23.501 – 23.503) with ALL features required to be implemented by vendors, but none of them mandatory for 5G network operators.   IEEE Techblog articles and tutorials for 5G security are here.

The STB was created to build on 5G security (presumably from the referenced 3GPP technical specs), testing use cases, making recommendations, and further bolstering 5G’s security to benefit consumers, enterprises, and government.

Governed by industry leaders, guided by government priorities, and managed by CTIA, the test-bed is the latest in a series of steps the industry has taken to make 5G the most secure network ever. Its founding members developed the initiative through their participation in CTIA’s Cybersecurity Working Group, which convenes the world’s leading telecom and tech companies to assess and address the present and future of cybersecurity.

The STB primarily focuses on verifying the Federal Communications Commission’s (FCC) Communications Security Reliability and Interoperability Council (CSRIC) VII recommendations for 5G networks. The FCC announced the working group members of the council last month.  There are six CSRIC VIII working groups:

-Working Group 1 is centered on 5G signalling protocols security and is co-chaired by Brian Daly of AT&T and Travis Russell of Oracle.

-Working Group 2 focuses on promoting the security, reliability, and interoperability of Open RAN equipment. It is co-chaired by Mike Barnes of Mavenir and George Woodward of the Rural Wireless Association.

-Working Group 3 focuses on using virtualization to promote security and reliability in 5G, co-chaired by Micaela Giuhat of Microsoft and John Roese of Dell

-Working Group 4 is centered on 911 service over Wi-Fi and is co-chaired by Mary Boyd of Intrado and Mark Reddish of APCO.

-Working Group 5’s area of focus is on managing software and cloud services supply chain security for communications infrastructure; the group is chaired by Rittwik Jana of VMWare.

-Working Group 6 will work on issues surrounding the use of mobile device applications and firmware for wireless emergency alerts. It is co-chaired by Farrokh Khatibi of Qualcomm and Francisco Sanchez of Harris County, Texas’ OHSEM.

The STB will also serve as a valuable industry resource for CSRIC VIII, focused on 5G security, which launched in June, and includes CTIA SVP and CTO Tom Sawanobori among its members.

“This initiative will complement and bolster the FCC’s 5G security efforts, validate its recommendations, and demonstrate 5G security features, with cross-industry groups working collaboratively to test use cases and products on an actual 5G network using real-world hardware and software,” said Sawanobori.

The test bed’s first configuration, built with Ericsson equipment, mirrors the initial setup for most 5G networks—a 5G radio access network is connected to a 4G core to create a 5G non-standalone (NSA) network. In 2022, the STB’s configuration will shift to a 5G standalone (SA) network using a 5G core, which will enable testing of 5G SA use cases.

The STB is located at a secure lab facility at the University of Maryland, leveraging personnel with extensive experience in wireless security. The wireless core network is hosted in Northern Virginia by MITRE, a not-for-profit research and development company.

The 5G Security Test Bed’s evaluations and recommendations cover issue areas that will help transform cities, government, and industries. Applications include autonomous vehicles, immersive augmented reality and virtual reality, automated factory operations, private 5G networks for enterprises, and much more.

CTIA debuts a 5G security testbed for commercial networks

5G Security explained: 3GPP 5G core network SBA and Security Mechanisms

by Akash Tripathi with Alan J Weissberger


5G networks were deployed in increasing numbers this past year. As of December 2021, GSA had identified 481 operators in 144 countries or territories that were investing in 5G, up from 412 operators at the end of 2020. Of those, a total of 189 operators in 74 countries/territories had launched one or more 3GPP-compliant 5G services, up by 40% from 135 from one year ago.

Despite 5G’s much advertised potential, there are significant security risks, especially with a “cloud native” service based architecture, which we explain in this article.

New 5G services, functions and features have posed new challenges for 5G network operators.  For example, bad actors could set up “secure” wireless channels with previously issued 5G security keys.

Therefore, it’s imperative for 5G operators to address end-to-end cyber security, using an array of novel techniques and mechanisms, which have been defined by 3GPP and (to a much lesser extent) by GSMA. 

5G Security Requires 5G SA Core Network:

It’s important to distinguish between 5G NSA network security (which use 4G security mechanisms and 4G core network/EPC) vs. 5G SA network security (which uses 5G core network serviced base architecture and new 5G security mechanisms as defined by 3GPP).  

Samsung states in a whitepaper:

▪ With the launch of 5G Stand Alone (SA) networks, 3GPP mitigates some long-standing 4G vulnerabilities to enable much stronger security.

▪ At the same time, the way the Service Based Architecture ‘explodes’ the new 5G Core opens up potentially major new vulnerabilities. This requires a fundamentally new approach to securing the 5G Core, including comprehensive API security.

▪ Operators can communicate 5G SA’s new security features to some business users. Communication to consumers is more challenging because the benefit of new security enhancements will only come into effect incrementally over many years.

▪ Mobile network security cannot depend on 3GPP alone. Operators must apply robust cyber security hygiene and operational best practice throughout their operations. 

In addition, the 5G network infrastructure must meet certain critical security requirements, such as the key exchange protocol briefly described below. 

There are many other risks and challenges, such as the rising shortage of well-trained cyber security and cyber defense specialists. We will address these in this article.  But first, a backgrounder….

5G Core Network Service Based Architecture (SBA):

To understand 5G security specifications, one has to first the 3GPP defined 5G SA/core network architecture.

5G has brought about a paradigm shift in the architecture of mobile networks, from the classical model with point-to-point interfaces between network function to service-based interfaces (SBIs)

The 5G core network (defined by 3GPP) is a Service-Based Architecture (SBA), whereby the control plane functionality and common data repositories of a 5G network are delivered by way of a set of interconnected Network Functions (NFs), each with authorization to access each other’s services.

Network Functions are self-contained, independent and reusable. Each Network Function service exposes its functionality through a Service Based Interface (SBI), which employs a well-defined REST interface using HTTP/2. To mitigate issues around TCP head-of-line (HOL) blocking, the Quick UDP Internet Connections (QUIC) protocol may be used in the future.

Here’s an illustration of 5G core network SBA:

The 5G core network architecture (but not implementation details) is specified by 3GPP in the following Technical Specifications:

TS 23.501 System architecture for the 5G System (5GS)
TS 23.502 Procedures for the 5G System (5GS)
TS 23.503 Policy and charging control framework for the 5G System (5GS); Stage 2

The 5G network consists of nine network functions (NFs) responsible for registering subscribers, managing sessions and subscriber profiles, storing subscriber data, and connecting user equipment to the Internet using a base station.  These technologies create a liability for attackers to carry out man-in-the-middle and DoS attacks against subscribers.

Overview of 3GPP 5G Security Technical Specifications:

The 5G security specification work are done by a 3GPP Working Group named SA3. For the 5G system security mechanisms are specified by SA3 in TS 33.501.  You can see all versions of that spec here.

3GPP’s 5G security architecture is designed to integrate 4G equivalent security. In addition, the reassessment of other security threats such as attacks on radio interfaces, signaling plane, user plane, masquerading, privacy, replay, bidding down, man-in-the-middle and inter-operator security issues have also been taken in to account for 5G and will lead to further security enhancements.

Another important 3GPP Security spec is TS 33.51 Security Assurance Specification (SCAS) for the next generation Node B (gNodeB) network product class, which is part of Release 16.

It’s critically important to note that ALL 3GPP security spec features and functions are required to be supported by vendors, but the are ALL OPTIONAL for 5G service providers.   That has led to inconsistent implementations of 5G security in deployed and planned 5G networks as per this chart, courtesy of Heavy Reading:

Scott Poretsky, Ericsson’s Head of Security, wrote in an email to Alan:

“The reason for the inconsistent implementation of the 5G security requirements is the language in the 3GPP specs that make it mandatory for vendor support of the security features and optional for the operator to decide to use the feature.  The requirements are defined in this manner because some countries did not want these security features implemented by their national telecoms due to these security features also providing privacy.  The U.S. was not one of those countries.”


Overview of Risks and Potential Threats to 5G Networks:

A few of the threats that 5G networks are likely to be susceptible to might include those passed over from previous generations of mobile networks, such as older and outdated protocols.

  1. Interoperability with 2G-4G Networks

For inter-operability with previous versions of software or backward compatibility, 5G must still extend interoperability options with mobile gadgets adhering to the previous generation of cellular standards.

This inter-operability necessity ensures that vulnerabilities detected in the outmoded Diameter Signaling and the SS7 Interworking functions followed by 2G-4G networks can still be a cause of concern for the next-generation 5G network.

  1. Issues related to data protection and privacy

There is a likely possibility of a cyber security attack such as Man-in-the-Middle (MITM) attack in a 5G network where a perpetrator can access personal data through the deployment of the International Mobile Subscriber Identity (IMSI)-catchers or cellular rogue base stations masquerading as genuine mobile network operator equipment.

  1. Possibility of rerouting of sensitive data

The 5G core network SBA itself could make the 5G network vulnerable to  Internet Protocol (IP) attacks such as Distributed Denial of Service (DDoS). Similarly, network hijacking, which involves redirecting confidential data through an intruder’s network, could be another form of attack.

  1. Collision of Politics and Technology

Government entities can impact 5G security when it comes to the production of hardware for cellular networks. For instance, various countries have new regulations that ban the use of 5G infrastructure equipment that are procured from Chinese companies (Huawei and ZTE) citing concerns over possible surveillance by the Chinese government.

  1. Network Slicing and Cyberattacks

Network slicing is a 5G SA core network function (defined by 3GPP) that can logically separate network resources. The facility empowers a cellular network operator to create multiple independent and logical (virtual) networks on a single shared access. However, despite the benefits, concerns are being raised about security risks in the form of how a perpetrator could compromise a network slice to monopolize resources for compute-intensive activities.

3GPP Public Key based Encryption Schemes:

3GPP has introduced more robust encryption algorithms. It has defined the Subscription Permanent Identifier (SUPI) and the Subscription Concealed Identifier (SUCI).

  • A SUPI is a 5G globally unique Subscription Permanent Identifier (SUPI) allocated to each subscriber and defined in 3GPP specification TS 23.501.
  • SUCI is a privacy preserving identifier containing the concealed SUPI.

The User Equipment (UE) generates a SUCI using a Elliptic Curve Integrated Encryption Scheme (ECIES)-based protection scheme with the public key of the Home Network that was securely provisioned to the Universal Subscriber Identity Module (USIM) during the USIM registration.

Through the implementation of SUCI, the chance of meta-data exploits that rely on the user’s identity are significantly reduced.

Zero Trust architecture:

As 5G will support a massive number of devices, Zero Trust can help private companies to authenticate and identify all connected devices and keep an eye on all the activities of those devices for any suspected transgression within the network. While it has been successfully tested for private enterprise networks, its capability for a public network like open-sourced 5G remains to be gauged.

Private 5G Networks:

A private 5G network will be a preferred mode for organizational entities that require the highest levels of security taking into account national interests, economic competitiveness, or public safety. A fully private 5G network extends an organization with absolute control over the network hardware as well as software set-up.  All of those mechanisms can be proprietary as the 5G private network deployment is only within one company’s facilities (campus, building, factory floor, etc).

Future of 5G Security:

The next-generation 5G-based wireless cellular network has put the spotlight on new opportunities, challenges, and risks, which are mandatorily required as the 5G technology makes great strides. 

The 5G security mechanisms will continue to evolve in 3GPP (with Release 17 and above).  Many of them will be transposed to become (“rubber stamped”) ETSI standards. 

Note that 3GPP has not submitted its 5G core network architecture or 5G security specifications to ITU-T which is responsible for all 5G (IMT 2020) non-radio standards.

Europe’s General Data Protection Regulation (GDPR), applicable as of May 25th, 2018 in all EU member states, harmonizes data privacy laws across Europe. It could serve as a model for network security and data protection initiatives outside the European Union.


The 5G network has the possibility to enhance network and service security. While 5G comes with many built-in security controls by design, developed to enhance the protection of both individual subscribers and wireless cellular networks, there is a constant need to remain vigilant and a step ahead in terms of technological innovation to thwart possible new cyber-attacks.

An end-to-end security framework across all layers and all domains would be essential. Introducing best practices and policies around security and resilience will remain imperative to future-proof 5G networks.

  • Major drivers for carrier 5G security include 5G core network implementation and support of private wireless networks
  • Leading carriers will transform 5G security from a cost of doing business into a major market differentiator for business customers

Note 1.  In February 2021 report, Markets and Markets said that 5G security market size is projected to grow from $580 million in 2020 to $5.226 billion by 2026, at a compound annual growth rate (CAGR) of 44.3%. The market research firm believes the major drivers for the 5G security market include rising security concerns in the 5G networks, increasing ransomware attacks on IoT devices, rising attacks on critical infrastructure, and increasing IoT connections paved way for mMTC with enhanced security requirement.

The “cloud native mode” of 5G core/SA deployment is expected to exhibit a higher CAGR during the forecast period. By deploying 5G security solutions and services on the cloud, organizations can avoid spending on hardware, software, storage, and technical staff.

The cloud deployment type is often used for both private and public clouds and may vary from case to case, depending on the requirement of the client.

Additionally, organizations can scale up or down, depending on their use of cloud-based 5G security services. The cloud deployment segment has witnessed strong demand in the early phase of the 5G standalone network. It offers a wide range of benefits, such as scalability, accessibility, flexibility, and cost-effectiveness.

Note 2.  Markets and Markets expects the APAC region to hold the largest market share during the forecast period. China, Australia, and Japan are the prime APAC countries that have started several 5G-related activities; which would provide growth opportunities for 5G security vendors in the region.

Asian telecom service providers, vendors, and government firms are determined to take the lead in 5G R&D. The infrastructural growth in APAC, especially in Japan, South Korea, Australia, Singapore, China, and India, and the increasing deployment of 4G and 5G networks present huge opportunities for the implementation of the 5G security solutions.


The report evaluates the 5G threat landscape as well as technologies and solutions to secure networks, platforms, devices, data, and applications [3.]. The report also assesses the 5G security market outlook and potential for many solutions, services, and support. It also evaluates the impact of security functions across various technologies including Mobile Edge Computing (MEC), IoT networks, and mobility infrastructure. The report includes market forecasts for all major technologies, industry verticals, solutions, and service types from 2021 to 2026.

The 5G security market must be robust as solutions need to be deployed on multiple levels including devices, air interface equipment, cloud RAN infrastructure, mobile backhaul facilities, and more.

Note 3.  There’s likely to be an increasing adoption of 5G security solutions by carriers. It will be used for identity management, differentiated security protection, privacy protection and growing demand for data protection worldwide.  5G security technology offers various benefits such as diversified system level protection of IT-aware infrastructure, security as service, and rapid detection and response.

The growing demand for a security monitoring and threat analysis to help the business to protect the integrity of systems and data is expected to create a huge opportunity for the global 5G Security market.

In addition, the need for E2E security for vertical industries from protection to detection and increasing importance of a unified security view across enterprise, are anticipated to drive the 5G Security market growth.



Among other areas, the 3GPP Security architecture and procedures for 5G System (Specification #: 33.501) specifies requirements for E1 and f1 interfaces as well as requirements for an overall secure environment. The organization specified many areas necessary for 5G security including subscription authentication, UE authorization, access and serving network authorization and more. Other areas include user and signaling data integrity to ensure seamlessness and interoperability between network elements.

Note that there are no ITU-T recommendations on 5G/IMT 2020 security.

One of the import areas emerging with 5G security that is a greater concern than ever before is data security and private. Much more so than LTE, 5G networks must be concerned with the confidentiality and integrity of user and signaling data. The 5G gNB must support encryption as per security policies for various potential vulnerability areas such as user data in transit as well as signaling for radio resource control. Access control is equally important as well as ensuring that serving networks are authorized by home networks.

5G mobile network operators need to expedite implementation of a more integrated 5G security approach, one of the primary areas of focus will be support of 5G-based private wireless networks for enterprise and industrial customers. While today’s private networks take a more old-school approach to security, more security-minded enterprise, industrial and government sector customers will realize greater cybersecurity through interconnection and managed services with leading carrier 5G security solutions.

Leading carriers will transform 5G security from a cost of doing business into a major market differentiator for business customers including direct to enterprise/industrial/government customers and via hybrid models involving neutral hosts and/or direct interconnect with private wireless networks. The challenging task for mobile network operators is to simultaneously convince business customers that they are more secure with them than without them, while not causing alarm about security holes that existed prior to implementation of 5G security solutions.

In a recent IEEE Future Networks presentation titled, Security Considerations for Evolving RAN Architectures, Scott Poretsky and Jason Boswell of Ericsson wrote about “the trust stack in 5G Cloud RAN.”  Here’s what they said (emphasis added):

Network security is built upon a trust stack of trusted hardware, trusted software, trusted deployment, trusted applications, and trusted operations.  Cloud deployments have an expanded attack surface due to decoupling of the software from the hardware, multiple organizations sharing the same hardware, a third-party organization managing the cloud infrastructure, and use of open source software components. 

The chain of trust between these disparate components is not standardized and is implementation dependent, making it challenging to determine the level of risk, such as defined by the NIST Risk Management Framework (RMF). In a cloud environment an external attacker could gain access to a compromised container and from there escalate privilege to gain access to services and infrastructure.  Likewise, an attacker that gains access to a service can use it as platform to gain access to containers and infrastructure. 



Report Linker: 5G Security Market to experience rapid growth through 2026

Report Linker forecasts that the global 5G security market will grow from USD 580 million in 2020 to USD 5,226 million by 2026, at a Compound Annual Growth Rate (CAGR) of 44.3% during the forecast period.

The 5G security market is gaining traction due to rising security concerns in the 5G networks, increasing ransomware attacks on IoT devices, rising attacks on critical infrastructure, and increasing IoT connections paved way for mMTC with enhanced security requirement. However, high cost of 5G security solutions will restrain the adoption by SMEs.

The implied negative flipside for operators and enterprises, of course, is that more money will have to be spent on tackling 5G vulnerabilities. The report pointedly notes that the high cost of 5G security solutions will limit adoption by SMEs.

Based on solution type, the DDoS protection solution segment is expected to grow with the fastest growth rate during the forecast period
The DDoS protection segment is projected to grow with the most rapid growth rate in 2020 to 2026.Enterprises use DDoS protection and mitigation solutions and services for adaptive defense against DDoS attacks.

These attacks further affect the confidentiality, integrity, and availability of resources, which may result in billion-dollar losses for enterprises.

Enterprises segment to grow at the highest CAGR during the forecast period
Enterprises are undergoing digital transformation across different industries. Businesses are in various stages of implementing new technologies to develop new solutions, improve service delivery, increase operational efficiency, reduce cost, gain competitive advantage, and meet rising customer expectations. 5G will soon make it into the list of technologies enterprise will consider, with standalone 5G solutions that will enable various new industrial applications, such as robotics, big data analytics, IIoT and AR/VR in engineering and design, as well as new ways to provide remote support and training. As a result, enterprises will need 5G security mechanism to secure the entire network, applications, and devices.


Asia Pacific (APAC) region to record the highest growth and also account for largest markety share in the 5G security market
APAC region is set to dominate 5G, edge computing, blockchain, and 5G security technology, due to its size, diversity, and the strategic lead taken by countries, including Singapore, South Korea, China, Australia, and Japan.These countries have always supported and promoted industrial and technological growth.

Also, they possess a developed technological infrastructure, which is promoting the adoption of 5G security solutions across all industry verticals.  Moreover, the region has become the center of attraction for major investments and business expansion opportunities.

While praises APAC for leading in 5G security, Europe is way behind if a recent report according to a report from the European Court of Auditors (ECA).

A year-long ECA probe into how European Union (EU) member states are dealing with 5G security found that while “member states have started to develop and implement necessary security measures to mitigate risks, they seem to be progressing at a different pace.”

More worryingly, Annemie Turtelboom, the ECA member leading the audit, indicated that some EU countries were bypassing supplier security checks in order to speed up 5G rollout.


Companies such as ZTE (China), Samsung (South Korea), and Huawei (China) are heavily investing in the upcoming 5G technology and are initiating field trials together with some of the leading mobile service carriers, such as China Telecom (China), KT (South Korea), SK Telecom (South Korea), China Mobile (China), SoftBank (Japan), and China Unicom (China).

• By Company Type: Tier 1 – 62%, Tier 2 – 23%, and Tier 3 – 15%
• By Designation: C-level – 38%, Directors – 30%, and Others – 32%
• By Region: North America – 40%, Europe – 15%, APAC – 35%, and Rest of the World (RoW)– 10%

This research study outlines the market potential, market dynamics, and major vendors operating in the 5G security market.
