With the present era of Vehicular Communication, a Vehicular Ad-hoc NETwork (VANET) is facing problem with vehicle anonymity and location privacy while communicating among the vehicle. To overcome that Vehicular Public Key Infrastructure (VPKI) has been used. Security becomes very important for VANET considering the criticality of safety application. In VANET authentication is a crucial security requirement to avoid attacks to both inter-vehicle and vehicle-to-roadside communication. Vehicles have to be prevented from the misuse of their private data and the attacks on their privacy.
