摘要
演进分组核心(Evolved Packet Core,EPC)是长期演进(Long Term Evolution,LTE)网络的核心网,它是一个支持全IP的、高速率的、基于分组的和低时延的扁平型网络,给人们带来良好用户体验的同时,也引入了一些安全隐患。主要从LTE核心网架构、接口和协议方面研究了LTE核心网面临的安全缺陷,分析了其可能导致的安全威胁,并提出了一系列安全性增强方案,使LTE系统更加安全。
The Evolved Packet Core（ EPC） is the core network of Long Term Evolution（ LTE）. It is a flatter network which supports all-IP,high-speed,packet-based and low-latency,and brings a better user experience but introduces some security risks. This paper mainly studies the security flaws of LTE core network from the network structure,interface and protocol of LTE core,discusses the security threats that may result in,and puts forward a series of enhanced security schemes to make the LTE system more secure.
