A Secure and Lightweight Authentication Protocol for Mobile User Preserving Privacy in Global Mobility Networks

Abstract

Abstract In two factor authentication schemes the key factor that has to be addressed is user anonymity and privacy preservation during roaming scenario in GLObal MObility NETwork. While roaming MU needs to access the services of the FA, FA grants the service request only to the authenticated MU. To verify the authenticity of the MU, FA sends the service request of MU to HA. HA verifies the authenticity of the MU after which FA allows the MU to access the services. The entire communication during roaming is carried over insecure channel. Due to this, several security concerns are raised. The main objective in GLOMONET is to secure the channel and the designed scheme should over come all active and passive security attacks. Since, the scheme is designed for mobile networks, it should be light weight with less communication cost, one such scheme has been proposed in this article. The proposed scheme is light weight with less communication cost. Additionally the proposed scheme addresses the active and passive security attacks. The scheme is efficient in terms of computational and communication cost. The proposed scheme is robust and practically implementable.
