摘要：Vehicular Ad-hoc Network (VANET) is vulnerable to many security threats including Sybil attack dueto its open infrastructure. In this paper we have proposed a scheme to detect Sybil attacks using Digital Signature. Theinfrastructure needed includes vehicles, Road Side Units (RSUs) and Department of Motor Vehicle (DMV). In Sybilattack the malicious node, called Sybil attacker, illegally claim multiple identities which are called Sybil nodes. In thispaper a Sybil attacker has been designed and a simulation environment on real world conditions has been implementedusing OSM maps, SUMO mobility generator and NS2 network simulator. The detection using Digital Signature doesnot require any vehicle to disclose its identity. Thus this scheme also preserves the privacy of vehicles.
