LMAM: A Lightweight Mutual Authentication Mechanism for Network Mobility in Vehicular Networks
Ming-Chin Chuang, Jeng-Farn Lee · 2008
RFC 3963 proposes a protocol, called the network mobility (NEMO) basic support protocol, for network mobility management. It is designed so that network mobility is transparent to nodes inside the mobile network, thereby reducing the signaling overhead. However, NEMO does not specify how authentication, authorization and accounting (AAA) should be handled. In this paper, we develop a lightweight mutual authentication mechanism (LMAM) based on NEMO combining with AAA model in vehicular networks with low computation cost and local authentication. Moreover, LMAM achieves the following security requirements: replay attack resistance, stolen-verified attack resistance, mutual authentication to prevent the server spoofing attacks, and session key generation. Our analysis results show that LMAM provides a better solution to the authentication procedure than existing schemes.
