With the widespread application of 5G networks, data transmission speed and capacity have been significantly 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 respectively, and improve the cracking efficiency of symmetric cryptography and hash algorithms. To address this challenge, 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 network terminal access and data transmission security were discussed. Finally, a quantum-secure cryptography application strategy was proposed and its technical feasibility was verified, in order to provide theoretical and technical references for building a more secure and reliable 5G network.
