CLAM: Cross-layer Localized Authentication Mechanism based on Proxy MIPv6 and SIP in Next Generation Networks

Abstract—In this paper we propose a novel Cross-layer Localized Authentication Mechanism (CLAM) to secure mobility in Next Generation Networks. The proposed mechanism integrates Proxy MIPv6 and Session Initiation Protocol (SIP) to handle the authentication locally in real-time and non-real-time communications. The design objectives of CLAM are three fold: i) handover latency is minimized by the local management of authentication; ii) simple to implement in mobile devices because of symmetric cryptographic and one-way hash operations; iii) possesses important security properties such as resistance against various attacks, user anonymity, mutual authentication, user friendly, one-time session key agreement, backward secrecy, forward secrecy, and confidentiality. We analyze and compare the performance of CLAM with existing schemes in terms of handover latency, signaling cost, communication overhead, computational cost, and packet loss. The numerical and simulation results demonstrate that our proposed scheme outperforms the existing schemes.
