Abstract: VANET (Vehicular Ad hoc Network) is an emerging research area. Finding location of a node in VANET is one of the most challenging issues in recent years. GPS receivers equipped inside the vehicles may lose satellite signals and calculate wrong positions due to signal blocking. Grid based scheme is a GPS-free localization method in which vehicles exchange location information and help each other to calculate accurate position for all the vehicles inside the network. However, since VANET is open and wireless in nature, probability for attack is very high. It requires a mechanism to help authenticate messages, identify valid vehicles, and remove malicious vehicles. A Public Key Infrastructure (PKI) can provide this functionality using certificates and public keys with the aid of RSUs (Road Side Units) that act as a gateway between the Certificate Authority (CA) and vehicles. The proposed scheme efficiently prevents eavesdroppers from generating harm to legal users and provides timely revocation of misbehaving participants, thereby contributing towards VANET security.
