Abstract
A Vehicular Ad Hoc Network (VANET) is a part of MANETs that is formed by wireless connections between cars. In VANETs, routing protocols and other routing related techniques must be adaptable to vehicular-specific capabilities and requirements. Along with the routing in VANET, message security is also one of the major concern. Messages are critical and important like a warning message, so that the message must be authenticated which guarantee's the message integrity. The authentication of these messages is done with the help of an algorithm called Elliptic Curve Digital Signature Algorithm (ECDSA), which provides an efficient message authentication scheme. A combination of AODV, ECDSA and VANET can make the scenario more efficient and perform better in terms of routing and time delay in message delivery.
