5G移动通信网络的安全研究

Research on Security of 5G Mobile Communication Network

随着移动通信和智能设备的迅速发展,第五代移动通信系统(5G)的商用落地,为用户提供更好体验、更为快捷流畅、稳定的通信服务.针对5G移动通信网络的安全,分别从新业务、新网络体系结构、新型空中接口技术和用户隐私的更高要求这4个方面来介绍5G移动通信网络的安全要求,并提出5G UE接入和切换方法、物联网的轻量级安全机制、网络切片安全隔离策略、用户隐私保护和区块链技术这5方面的保护应对策略.

With the rapid development of mobile communications and smart devices,the commercial implementation of the fifth generation mobile communication system(5G)provides users with a better experience,faster,smoother,and stable communication services.Aiming at the security of 5G mobile communication network,The security of 5G mobile communication network is introduced from four aspects of new services,new network architecture,new air interface technology and higher user privacy requirements,and proposed five aspects of protection and response strategies,which contain 5G UE access and switching methods,lightweight security mechanism of the Internet of things,network slice security isolation strategy,user privacy protection and blockchain technology.
