摘要
5G核心网引入了服务化架构,以及软件定义网络、网络功能虚拟化等新技术,呈现出IT化和互联网化等特点。新架构和新技术在给5G带来便利的同时也引入了新的安全威胁,尤其是因未知漏洞或后门等带来的未知安全威胁。主要介绍了软件定义网络、网络功能虚拟化等技术自身的安全威胁,在其基础上归纳总结了标准化组织和学术界提出的安全解决方案,并提出了基于内生安全防御思想构建高等级安全5G核心网的新思路。
5G core network introduces service based architecture,software defined network(SDN),network function virtualization(NFV)and other new technologies,showing the characteristics of IT and Internet.The new architecture and new technologies not only bring convenience to 5G,but also introduce new security threats,especially the unknown security threats caused by unknown vulnera-bilities or backdoors.This paper mainly introduces the security threats of SDN and NFV.On this ba-sis,it summarizes the security solutions proposed by standardization organization and academic cir-cles,and puts forward a new idea of constructing high-level security 5G core network based on the i-dea of endogenous security defense.
