移动网络中的独立式安全管理系统

Independent Security Management for the Mobile Network

本文提出一种适用于移动网络的安全管理系统 ,由于访问网络能够独立地对漫游用户进行认证 ,所以称该系统为独立式安全管理 (ISM) .基于ISM设计一种漫游用户的认证协议 ,通过对协议的比较分析可以看出 ,相对于其它安全管理系统 ,ISM的突出优点是安全责任划分清晰。

This paper proposes a new security management system for the mobile network,which uses the asymmetric cryptosystems to authenticate the mobile users.As the visited network can authenticate the user independently in roaming,the system is called independent security management (ISM).An authentication protocol based upon ISM is given.As shown in our analysis,the greatest advantage of ISM over other security managements is that the security responsibility is made clear and the authentication procedure is more efficient.
