In case of wireless access networks significantly changes the way we live and work, bringing us closer anywhere at any time. Security, privacy, accountability, and efficiency issues are of most concern in such networks. because of need and importance, little research has been conducted on designing accountable and privacy-preserving authentication schemes for wireless access networks, and this motivates us to develop an authentication framework, namely APEA using Attribute Based Encryption, that defines new form of APEA while Existing version of APEA integrates a key management protocol, where key transfer mechanism is more complicated , time consuming and less secure In our proposed approach attribute based encryption does is that, it effectively binds the access-control policy to the data and the users(clients) instead of having a server mediating access to files. An effective approach to simultaneously achieve the four goals without involving any trusted third party. However, with the requirement of wireless area network security solution, this paper presents the various techniques on WAN authentication with certain constraints and analyzes their strengths and weaknesses
