Vehicular ad hoc networks aim at increasing safety by exchanging emergency messages between vehicles using wireless communication. VANET provides a promising network safety on roads, managing traffic, and infotainment dissemination for both passengers and drivers. A main challenge is to resist to various malicious abuses and security attacks. Authentication is a common tool for ensuring information reliability, data integrity and authenticity; it faces a challenge in VANETs. When the number of messages received by a vehicle becomes large, traditional authentication schema may generate unaffordable computational overhead on the vehicle and therefore bring unacceptable delay to time-critical applications, such as accident warning. However, authentication of vehicles using a PKI or any other cryptography based architecture which is mostly based on V2I communication and solely depends on Road Side Units or any centralized system, might fail in case of absence of proper infrastructure. All these schema based solutions incur more communication overhead due to repeated connections with the Trusted Authority or RSUs every time you want to authenticate a vehicle. In this paper reviewed different authentication schema.
