A Mobile User Authentication Technique in Global Mobility Network

Abstract

Anonymous user authentication always is a paramount job in global mobility network (GLOMONET). In GLOMONET, a mobile user can move from one place to another place causes changes of mobile network from one to another. As authentication server can authenticate only its registered users, it cannot verify other mobile users. Furthermore, in global mobility network, communication channel is public. An adversary of the network can get access of all transmitted messages over the channel. In such a situation, several network security attacks can be initiated by an adversary to decrypt the messages. Therefore, mobile users as well as network provider’s information may come in risk. A robust anonymous user authentication and key agreement technique required to ensure the protection of such information. Several authentication protocols have been designed in GLOMONET in recent years. Unfortunately, most of them are unprotected against various network security attacks. Therefore, in this paper, we proposed a rigid authentication protocol in GLOMONET to overcome all the deficiencies of the previous work. Performance analysis of our protocol shows that it is reliable and even more effective compared to other existing protocols.
