摘要： 不同网络同时维护多套认证设施会大幅降低异构融合网络的接入效率，多套认证机制中的短板效应也会降低融合网络中的安全性能。为此，提出基于用户、位置、寻址的信息分离技术，从移动通信系统对安全的需求出发，分析并借鉴3G网络认证与密钥分配协议，在异构无线网络环境中建立基于统一用户标识的的认证方案。仿真测试结果表明，该方案实现了异构网络和移动终端的统一接入及安全 认证。

Abstract: For the problems that the different networks maintenance multi authentication facilities together in the process of integration, the access efficiency will be reduced largely, and the security performance will be reduced because of the short slab effect of several kinds of authentication mechanism. This paper proposes the information separation technology based on the idea of the separation of identity, position and addressing, borrows ideas from the authentication and key agreement protocol of 3G, researches and builds the access authentication plan based on unified identity in heterogeneous wireless networks. Test result shows that it solves the problems of unified accessing and security authentication.

Key words: identity, heterogeneous networks, integration, identity hiding and substitution, access authentication
