Abstract

Vehicular communication is one of the growing aspects in the communication industry. Cooperative Intelligent Transportation Systems (CITS) in view of a correspondence among vehicles and clever roadside foundation can be of an extraordinary advantage with respect to street security, traffic blockage and ecological effect of the vehicle. Some characteristics of VANET are high mobility of the nodes, dynamic nature of the network, self-organisation and distributed networking. In such a communication system, it is difficult to establish a fixed security model. Because of high mobility of the nodes, the nodes may be exposed to multiple security attacks. The packet communication in VANET is open-environment making it susceptible to attacks. Such attacks may damage the nodes and the network entirely. There are various studies related to the security in VANET. But the security field in VANET is ever growing as there cannot be a limit to the ways which the attackers may exploit and harm the network. Some schemes have been proposed for the security in VANET. These schemes have been implemented via simulations of the network because it is hard to establish and monitor a vehicular ad hoc network physically. The paper presents an overview of the security in VANET by discussing various security attacks, attackers and a few proposed schemes based on security
