第5代移动通信系统 (5G) 对安全提出了不同以往的更高要求。相应的，国际标准组织、运营商和设备制造商等对5G安全技术给与了极大关注。

Science China Information Sciences在2018年第8期即将出版来自季新生教授撰写的综述 “Overview of 5G Security Technology”。

文章系统梳理了5G业务应用、网络架构、空中接口以及用户隐私方面的安全需求。在此基础上，总结了5G安全总体架构的发展趋势，重点介绍了代表5G安全发展新潮流的内生防御架构，并点评了5G安全若干增量型支撑技术，包括物理层安全、轻量级加密、网络切片安全、用户隐私保护以及区块链技术在5G中的应用等。

Abstract

The 5th-generation mobile communication system (5G) has higher security requirements thanprevious systems. Accordingly, international standard organizations, operators, and equipment manufacturers are focusing extensively on 5G security technology. This paper analyzes the security requirements of 5G business applications, network architecture, the air interface, and user privacy. The development trends of 5G security architecture are summarized, with a focus on endogenous defense architecture, which represents a new trend in 5G security development. Several incremental 5G security technologies are reviewed, including physical layer security, lightweight encryption, network slice security, user privacy protection, and block chain technology applied to 5G.
