移动通信网鉴权认证综述

随着移动通信网技术的演进，网络安全问题日益突出，如何在提供高质量通信服务的同时保护合法用户的隐私不被非法窃取、运营商网络不被入侵成为移动通信安全领域的一个重要问题。用户与网络的相互鉴权是用户和网络彼此判定对方合法性的重要手段，鉴权手段也随着网络演进而不断演进，从历代移动通信网络（GSM、CDMA、UMTS、LTE）鉴权认证技术入手，分析鉴权技术优缺点，并重点剖析了即将商用的第五代（5G）移动通信的鉴权技术、统一认证技术，最后对未来鉴权技术的发展进行了展望。

Overview of mobile communication network authentication

With the increasingly serious security situation of mobile communication network,it becomes an important issue about how to protect the privacy of legitimate users while providing high-quality communication services,and how to protect the carrier network from being invaded becomes an important issue in the field of mobile communication security.Authentication is an important means for users and networks to authenticate each other's legitimacy.Authentication methods are also evolving along with network evolution.Starting with the authentication methods of past mobile communication networks (GSM,CDMA,UMTS,LTE),the advantages and disadvantages of each generation of authentication technology are analysed,along with which the authentication technology and unified authentication technology of the fifth-generation (5G) mobile communication to be commercialized are emphatically analysed.In the last,reasonable prospect for the development of authentication technology in the future are proposed.
