HMAC Based Secure Authentication of VANETs

Swagat. S. Gudagudi | Dr. Veena Desai

Abstract: The Vehicular Ad-hoc Network (VANET) has been studied in many fields since it has the ability to provide a variety of services, such as detecting oncoming collisions and providing warning signals to alert the driver. The services provided by VANET are often based on collaboration among vehicles that are equipped with relatively simple motion sensors and GPS units. Awareness of its precise location is vital to every vehicle in VANET so that it can provide accurate data to its peers. Hence the data in VANET communicating between sender and receiver must not be revealed or modified by other impersonators or other vehicles participating in network. In this proposed work the authentication of the vehicles (nodes) by using Hash based message authentication of nodes is computed and the message digest function can be used of either MD-1, 256, 512 for the message integrity and the symmetric key mechanism is performed. The simulation is done by using MatLab tool
