Identity Based Secure Algorithm for VANET

Abstract Vehicular ad hoc network is an emerging technology, consists of vehicles and road side units as network nodes and enables inter-vehicle communications along with the road side to vehicle communications. Vehicular Ad hoc network (VANET) can offer various services and benefits to users and the deployment of vehicular communication systems is strongly dependent on their security and privacy features. Security has become a prime concern in providing communication between wireless mobile nodes in a hostile environment. Privacy, authentication, confidentiality and non repudiation are the most desired security attributes for all VANETs applications. In this paper we have presented a brief review of state of the art scenario of routing protocols and present a new identity based secure algorithm for VANET. The primary objectives of this solution include the management of identities using signam, pair of public-private key and hash function, the security of communications, and the integration of privacy enhancing technologies. Providing privacy and security, our proposed routing scheme does not introduce any complexity and computational overheads.
