5G移动通信网络安全研究

摘要

The fifth generation mobile communication network,abbreviated 5G network or 5G,is also called the next generation of mobile communication network,which aims at constructing a networked society and realizing the goal of "everything-connecting".With 4G mobile communication network entering the commercial stage,the research on 5G has gained wider attention all over the world.The realization of the vision for 5G needs the revolution and innovation of system structure and core techniques,and until now the corresponding techniques and standards are in the primary stage.The new architectures,new business,and new technology bring new challenges to 5G security.This paper briefly summarizes performance,key technology,application scenario,and standardization progress of 5G,analyzes the security requirements and challenges of 5G,introduces 5G security framework,and investigates some key issues and the corresponding solutions based on the research efforts,white paper and related standards.Furthermore,the paper discusses the current research trends in industries and academia in the context of 5G security.%第五代(fifth gneration,简称5G)移动通信网络(简称5G网络或5G),是为构建网络型社会并实现万物互联的宏伟目标而提出的下一代移动网络.随着LTE等第四代移动通信网络进入规模化商用阶段,5G网络的研究已成为世界各国的关注焦点.5G网络的实现,需要依赖于系统架构和核心技术的变革与创新.目前,5G网络还处于技术和标准的初级研究阶段.5G网络的新架构、新业务、新技术对安全提出了新的挑战.简述了5G的性能指标、关键技术、应用场景及标准制定的进展,分析了5G网络的安全需求及其所面临的技术挑战.基于目前已有的研究工作和标准研制情况,提炼了5G安全框架,归纳并阐述了若干安全关键问题及其解决方案,展望了5G网络安全的未来研究方向.
