Due to the advantages of low handover latency and signaling costs, Proxy Mobile IPv6 (PMIPv6), as a localized mobility management protocol for next generation mobile network, can be well combined with vehicular ad-hoc networks. However, the lack of security considerations limits the rapid growth of PMIPv6. Unfortunately, few proposals are in the literature to address such issue. Motivated by this, a novel authentication scheme based on identity-based signature for PMIPv6 is proposed. Mutual authentication between mobile node and mobile access gateway is achieved for both intra-domain and inter-domain scenarios with the help of identity-based signature and service-level agreement. The authentication signaling can be finely integrated into the mobility management procedure of PMIPv6, which equips our scheme with high authentication efficiency. The formal security proof under SVO logic and the performance analysis are presented to demonstrate the robustness and efficiency of our proposed scheme.
