An Asymmetric Key Based Efficient Authentication Mechanism for Proxy Mobile IPv6 Networks

Proxy Mobile IPv6 (PMIPv6), a network-based localized mobility management protocol, provides efficient mobility management support to mobile nodes without their participation in mobility-related signaling. However, PMIPv6 suffers from inefficient authentication procedure during hand-off. Very few work on PMIPv6 handover procedures consider the security threats to PMIPv6 network and most of them use symmetric key based authentication. In this paper we propose an asymmetric key based authentication cum handoff technique for PMIPv6 networks. The simulation results show that our proposed authentication cum PMIPv6 handoff technique outperforms the other existing authentication procedure based PMIPv6 handoff technique in terms of handover latency as well as signaling cost.
