[Abstract] The 5th generation (5G) mobile communication system has put forward higher security requirements than ever before. Accordingly, the international standard organizations, operators and equipment manufacturers have paid much attention to the 5G security technology. The security requirements of 5G business applications, network architecture, air interface and user privacy are elaborated. The development trend of 5G security architecture is summarized. Especially, the endogenous defense architecture representing the new trend of 5G security development, as well as several incremental supporting technologies are addressed in detail, including physical layer security, lightweight encryption, the network slice security, user privacy protection and applications of block chain technology in 5G.

1 引言
作为新一代移动通信技术,5G不仅将用于人与人之间的通信,还将用于人与物以及物与物之间的通信,实现真正的“万物互联”。国际标准化组织3GPP已经定义了70多种5G的需求[1],主要可分为3种场景,即增强移动宽带(eMBB, enhanced Mobile Broadband)、海量机器类通信(mMTC, massive Machine Type Communication)和超可靠低时延通信(uRLLC, ultra-Reliable Low Latency Communication),所需发展的关键技术包括大规模天线阵列、多载波技术、全双工复用、超密集网络、软件定义网络、网络功能虚拟化等[2]。
5G新业务、新架构、新技术、新应用场景的不断发展,给5G安全技术研究提出了新的挑战,同时5G新的技术发展又为解决传统安全问题提供了新的机遇。业界也期望采用不同于以往的发展思路,加大架构型、内生型安全技术的研究力度,努力克服通信與安全“两张皮”和“补丁式安全”等弊端[3],实现“打造自带安全基因的5G”愿景。……
