Provably secure mutual authentication and key agreement scheme with user anonymity

With the widespread use of several mobile gadgets, privacy and anonymity of the mobile subscriber becomes a major issue in mobile communication. Through the roaming technology of the global mobility networks, a legitimate subscriber can enjoy the ubiquitous services. Where, the mutual authentication and key agreement between the mobile subscriber and roaming network (VLR/SGSN) is the primary security aspect of many commercial mobile networks. For personal privacy perspective, it is important to develop a mutual authentication and key agreement scheme with several security features including the user anonymity. In this article, we come up with a novel authentication and key agreement scheme, which can assure privacy against eavesdroppers (PAE) with the subscriber anonymity. Simultaneously, here we argue that the proposed scheme can also withstand several other security vulnerabilities like redirection attack, forging-mobile-user attack and location privacy etc. with the less communication cost.
