Abstract: 

Authentication in Vehicular Ad-Hoc Network, or VANET, is of prime importance for safety of vehicles on roads. It has been found that lack of authentication in VANET can result in communication of false information among vehicles by any malicious node which can lead to accidents. In order to prevent vehicles from these attack, many techniques have been developed for authenticity .Techniques used for authentication has changed with time, but it has been found that in most of the authentication schemes the prime focus is to authenticate vehicles through road side unit (RSU), but in this paper, a novel authentication scheme is proposed which authenticate vehicle as well as road side units. It is a ticket based authentication scheme for VANET that is authenticating not only vehicle but also road side units. This scheme also tried to eliminate the overhead of repeating same procedure over  again, when a vehicle enters the reign of another road side unit.
