A Novel Architecture for Authentication and Secure Communication in VANET

Authenticate communication model provides secure inter and intra vehicles communication. This architecture uses the concept of distributed database. Every driver has to prove his identity to certified authority to get the communication rights to communicate with other vehicles. Vehicular ad-hoc network for intelligent transport system (ITS) which has become an essential service, provides safety and convenience services like mobile nodes communication, electronic toll collection system, real time audio, collision avoidance, road side safety, traffic jam using cellular phone. In this paper we present a novel architecture for user authentication and communication in Vehicular Ad hoc Networks. Keywords— Wireless communication network (WSN), VANET, GPS, WLAN, CA (Certifying Authority).
