基于整个网络的3G安全体制的设计与分析*

Design and analysis of the overall network-based 3G security scheme

首先提出了一个3G网络域内的安全体制,实现了网络域内实体之间的安全信息交互以及认证;在此基础上,进一步提出了一个在整个3GPP范围内的全网络范围内的安全结构,从而实现了UE之间的任意安全通信,并且对此结构的协议、算法和密钥进行了安全性分析,证明其是安全的。

A security scheme in the 3G network domain is presented first. Secure transmission of traffic and mutual authentication between entities of in the network domain is achieved ;Based on this ,Awhole 3G security scheme in the entire network is proposed .Secure traffic transformation between UEs is evaluated. On the analysis of the protocol, algorithm, and key used in the scheme ,the scheme is secure.
