Vehicular Ad hoc Networks (VANET) is a subgroup of (Mobile Ad Hoc Networks) MANET which is using for improves traffic safety system. Since the movements of Vehicles are restricted by roads, traffic regulations we can deploy fixed infrastructure at critical locations. We focus our study on the different kind of attacks based on security algorithm and protocol and routing. In this paper we review secure key algorithms and protocols for sharing information in VANET Systems. After surveying we found that attacks in multilayer are very harmful for security system as well as authentication and privacy are big challenges.
