Abstract

Vehicular networks are a fast developing research topic which is useful for the area like traffic efficiency enhancement and safety application. VANET (Vehicular Ad-Hoc Network) is considered as an intelligent transport system where in the vehicles can able to communicate with each other and also with the road side infrastructure. Since the message exchange between two vehicles are ad-hoc in nature and the driver behavior and high mobility of the vehicle, there is a chance of privacy and security problems and also the authentication is an another issue for any secured interactions due to the VANET has a unsecured and untrusted nature. The paper reviews various existing authentication protocols used for efficient privacy preserving authentication in the VANET.
