Abstract

AAA(Authentication, Authorization, Accounting) protocol is an information security technology that offer secure and reliable user Authentication, Authorization, Accounting function systematically in various services, protocol and wireless network as well as wire network. Currently IETF(Internet Engineering Task Force) AAA Working Group deal with about AAA protocol and studying with activity.But, recently it exposing much problems side to user's anonymity and privacy violation. Therefore, in this paper, AAAH(Home Authentication Server) authenticates Mobile device. after that, use ticket that is issued from AAAH even if move to outside network and can be serviced offering authentication in outside network without approaching by AAAH. Also, we study mechanism that can offer user's privacy and anonymousness to when use service. Our mechanism is using Time Synchronization OTP and focusing authentication and authorization. Therefore, our mechanism is secure from third party attack and offer secure and effective authentication scheme. Also onlyright user can offer services by using ticket, can reduce signal and reduce delay of message exchanged, can offer persistent service and heighten security and efficiency.
