Research on the application of quantum-secure algorithms in 5G network
With the widespread application of 5G networks,data transmission speed and capacity have been signifi-cantly improved,promoting innovative development in fields such as the Internet of things,autonomous driving,and telemedicine.At the same time,higher requirements are put forward for network security.The progress of quantum computing technology poses a major threat to the traditional public key cryptosystem.Shor's algorithm and Grover's algorithm can crack public key cryptography based on the holeyer factorization and discrete logarithm problems re-spectively,and improve the cracking efficiency of symmetric cryptography and hash algorithms.To address this chal-lenge,multiple global standardization organizations are actively promoting the research and standardization of quantum-secure cryptography.Firstly,the 5G network architecture and its security requirements were outlined,and the impact of quantum computing on traditional cryptography was analyzed.Subsequently,the latest progress of quantum-secure cryptography algorithms was introduced,and the integration methods of these algorithms in 5G net-work terminal access and data transmission security were discussed.Finally,a quantum-secure cryptography applica-tion strategy was proposed and its technical feasibility was verified,in order to provide theoretical and technical refer-ences for building a more secure and reliable 5G network.
