Verification Based Authentication Scheme for Bogus Attacks in VANETs for Secure Communication

A Vehicular Ad Hoc Network (VANET) is a subclass of mobile ad hoc network (MANET), which includes smart vehicles and roadside units (RSU). It maintains vehicle to vehicle (V2V) and vehicle to infrastructure (V2I) communications. The significant features of VANET contain self-organization, distributed networking, and highly dynamic topology. As the transmission of the message is in an open-access environment, like VANET, leads to the most critical and challenging security issues. Due to these critical concern, it is important to develop security mechanisms to detect and mitigate the VANET attacks. There are three authentication schemes in VANET such as Cryptography techniques, Digital signatures and Message Verification techniques to develop security mechanisms against VANET attacks, but some of the attacks are not addressed by these schemes. In this paper bogus attack is mitigated by using Position Verification Technique in which the effects of falsified position information are analyzed primarily. In order to reduce these problems, detection mechanisms are used to detect the cheating nodes and mitigate the effect of bogus node (false position information). The solution is evaluated based on simulation and the position verification system, that successfully prevent nodes from spreading false positions and thus the bogus attack can be mitigated.
