Non-redundant identifier-based authentication scheme for heterogeneous wireless network

In heterogeneous wireless network, its open and interconnected characteristic challenges current secure mechanisms, To enhance the security and reduce the redundant identifiers of users, An access authentication scheme based on the non-redundant identifier is proposed. The scheme is to realize identifier authentication, through using identity separating storage, substitute transmission and identifier updating mechanisms, user privacy protection is enhanced. This paper also improves AKA algorithm to enhance the security of access authentication. Finally, security and communication performance of the proposed protocol are analyzed. The result showed that the proposed scheme is efficient and secure met users' requirements in access security.
