In wireless communication system, the real identity, current location and movement mode of user are important and sensitive information, and their confidentiality must be ensured. Especially, in heterogeneous wireless integrated networks, the key factor for attracting client is to protect the network information. Every identity can be used indicating the Fig. and location of each entity. But coupling relation and binding transfer of identity can result in divulging sensitive user information. The identity technology to avoid divulging sensitive user information has become a hot topic of research in communication field. In face of the complicated heterogeneous wireless environment, it’s important but difficult to design a perfect identity technology. In view of above problem and security of heterogeneous wireless integrated networks, the related solution is proposed. It can improve the efficiency of trusted connection and handoff between heterogeneous networks.
