A novel approach to enhance the Security in Vehicular Ad-Hoc Network through Node Authentication using Hash Value and Steganography Schema

VANET is a vehicular ad hoc network where a shortlived network is formed among the VANET nodes. VANET nodes communicate and interchange messages with other vehicular nodes either in an infrastructure or infrastructure-less network. Due to lack of fixed infrastructure, VANET is prone to varied attacks. In impersonation attack, identity of the legitimate node is stolen by an attacker. In this paper, an enhanced level of security is implemented on the VANET system to reduce malicious activates into the network. Here the security is done by the authentication of individual node by some enhanced scenario which is based on the HASH value and steganography technique. Each vehicle will be authenticate by centralize authentication and it will helps to reduce the malicious activates. Index Terms – VANET, HASH, RSU, V2V, V2I.
