Abstract: In vehicular Adhoc networks, moving vehicles are enabled to communicate with each other. VANETs usually face message authentication delay due to revocation checking process as each OBU( On Board Unit) check the revocation status of all the received certificates in a timely manner by checking the CRL( Certificate Revocation List) for each received certificate. In this paper we have implemented and enhanced expedite message authentication protocol (EMAP), an efficient revocation checking process using a fast and secure HMAC function and novel key sharing scheme employing probabilistic random key distribution which allows an OBU to update its compromised keys even if it previously missed some revocation messages. This reduces the message authentication delay and the work load of Trusted Authority (TA). A privacy preserving algorithm for V2I (Vehicle to Infrastructure) is also proposed in which message can be sent using pseudo identity and this identity can be verified by the RSU (Road State Unit). The revocation process and privacy preserving is simple and efficient and it makes the VANET working fast and the OBUs in the V2I infrastructure secure.
