With the rapid advancement of artificial intelligence, quantum technology, and evolutionary networks 5G-A and 6G, the significance of mobile communication network security has become increasingly prominent. Cryptogram, as the fundamental element in ensuring network security, plays a crucial role in building the security capacity of mobile communication networks. However, the existing 5G network cryptography technology system is no longer able to fully meet the ever-changing security requirements. Therefore, it is necessary to accelerate the research on the enhancement of cryptographic technology applications in 5G networks and evolutionary networks, form a new quality of productivity for the integration of cryptogram and mobile communication networks, and enhance the security of 5G networks and evolutionary networks.This article focuses on enhancing cryptographic security technology for 5G and evolving networks, analyzing the feasibility of integrating cryptographic security enhancement technology, and exploring end-to-end cryptographic security enhancement methods from terminal devices to wireless transmission systems, core network infrastructure, and enterprise platforms. The topic of this article provides reference for the research and application of cryptographic security enhancement technology in subsequent networks.
