A Vehicular Adhoc Network (VANET) is a sub-class of Mobile Adhoc Network (MANET) which provides vehicle to vehicle communication and vehicle to infrastructure communication, i.e., between vehicles and Road-Side base stations. The presence of Vehicular technology in the present automotive industry owes to its increasing number of applications with a good resource for the Intelligent Transportation System. The designed system uses the road side unit (RSU) to ensure the originality of the vehicles which is sending messages and also to prevent redundant messages. With large computing power, it stores all information about the vehicle and provides a pseudo id to the vehicle for communication, thereby anonymity is preserved. The RSU verifies the vehicle id, and the freshness of the message is verified by using timestamp. Once the details are verified, it finally broadcast the message to all vehicles and other RSUs that may need the information, thereby arresting redundant messages. Cryptographic algorithm is applied for encryption and decryption of messages, ensuring secure messages.
