Secure Biometric-Based Authentication Protocol for Vehicular Ad-Hoc Network

Vehicular ad-hoc Network(VANET) helps various stakeholders like passengers, traffic management team, manufacturers, owners, drivers etc to access important information using a highly dynamic mobile network. Restricting unauthenticated users from free information sharing is a crucial challenge. In this paper we propose a dynamic lightweight biometric-based authentication protocol for vehicle-to-vehicle (V2V) communication networks where user after successful registration can directly login from any local mobile terminal and access his /her services/information directly from the authentication servers. We have done the security analysis of our scheme and prove that our scheme provides user anonymity, location privacy, mutual authentication to prevent spoofing attacks and resistance against forgery, modification and replay attacks. We also compare the efficiency of our scheme with other related schemes and show that our authentication scheme is more secure and performs faster than other schemes available in the literature.
