SK Telecom (SKT) and Thales have marked a significant milestone in telecommunications security by successfully integrating post-quantum cryptography (PQC) into their 5G test network. This collaborative effort demonstrates the seamless operation of high-security communication network authentication, safeguarding against potential threats posed by quantum computing advancements.
Pioneering Technical Test
The technical test conducted by SK Telecom and Thales involved the application of quantum cryptosystems (QKD), post-quantum cryptosystems (PQC), and quantum random number generators (QRNG) to terminals and communication networks. The initiative aims to fortify existing security systems, ensuring resilience against emerging threats from quantum computing technologies.
Seamless Operations Validation
Working in tandem, SK Telecom and Thales applied post-quantum cryptographic algorithms for encryption and key exchange to SIM and 5G authentication systems within the 5G network. The successful test showcased seamless operations, including registration, authentication, and receiving calls, even when employing post-quantum encryption algorithms alongside existing security systems.
Future-Ready API Development
In a forward-looking move, SK Telecom and Thales jointly developed the post-quantum cryptographic framework of this technical test as an API. This lays the foundation for future communication network authentication and services like Machine-to-Machine (M2M) and Internet of Things (IoT) that demand enhanced security measures.
Commenting on the test, SK Telecom emphasized the significance of strengthening the security and stability of long-term communication networks in the face of quantum computing advancements. The company affirmed its commitment to ongoing research into security systems covering both communication networks and future services.
Global Leadership in Security Standardization
SK Telecom’s future plans include securing a differentiated solution for communication network security based on the success of post-quantum cryptography in this technology test. The company aims to lead global network security standardization, particularly in the realms of 5G-Advanced, 6G, and IoT development in the foreseeable future.
