5G安全威胁及防护技术研究

摘要

The 5G mobile communication system can provide users with higher data rate, greater capacity, cheaper cost, as wel as better user experience. But the security chal enges also become more complex to handle. It firstly analyzes the existing security archi-tecture and network security model, puts forward the security requirements of 5G. Based on these requirements, it gives the potential research orientations of the security protection technologies.%第五代移动通信系统（5G）以更快的速度、更大的容量、更低的成本为用户提供更丰富的业务和更好的用户体验，同时也带来了更多安全挑战，面临的安全威胁更加广泛而复杂。首先分析了现有的安全体系架构和网络安全模型，给出了5G网络的安全需求，并基于此给出了可能的安全防护技术研究方向。
