Vehicular Ad Hoc Network (VANET) is vulnerable to many security threats. One severe attack is Sybil attack, in which a malicious node forges a large number of fake identities in order to disrupt the proper functioning of VANET applications. In this paper, a distributed and robust approach is presented to defend against Sybil attack. Proposed scheme(More)
The motivation behind Vehicular Ad Hoc Networks (VANETs) is to improve traffic safety and driving efficiency. VANET applications operate on the principle of periodic exchange of messages between nodes. However, a malicious node may transmit inaccurate messages to trigger inevitable situations. Each transmitted packet contains the status of sender like its(More)
