VANET may be defined as the vehicular ad hoc network where cars act as a wireless data transmission to pass signals. The main role of the cars is to propagate data from one end to another end of the network that's why there is a inbuilt router fitted inside the car. In VANET network every car tends to move in higher speed and their speed varies from node to node so it is necessary to hold every data in secure form in order to have accuracy of data. Since VANET is a wide area network thus it is necessary to keep network under strong security in order to avoid threat.
