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.
