Review on Message Authentication Protocol for Vehicular Ad Hoc Network

Sarika A. Velukar, Dr. M. S. Ali

Abstract: Intelligent Transportation Systems are aimed at addressing critical issues like passenger safety and traffic congestion, by integrating information and communication technologies into transportation infrastructure and vehicles. They are built on top of self organizing networks, known as a Vehicular Ad hoc Networks (VANET), Vehicular communication systems facilitate communication devices for exchange of information among vehicles and between vehicles and roadside equipment. As vehicles communicate through wireless network, variety of attacks can take place like injecting false information and modifying messages. A security attack on VANETs can have severe harmful or fatal consequences to legitimate users. So there is need to have secure vehicular communications. A novel solution to secure VANETs is to deploy Public Key Infrastructure (PKI), and to use Certificate Revocation Lists (CRLs) for managing the revoked certificates. For this purpose a new Message Authentication Protocol is proposed for VANETs, which replaces the time-consuming CRL checking process by an efficient revocation checking process. The revocation check process uses a keyed Hash Message Authentication Code. This new protocol significantly decrease the message loss ratio due to the message verification delay and end to end delay compared with the conventional authentication methods employing CRL.
