A DTSA (detection technique against a sybil attack) protocol using SKC (session key based certificate) on VANET

초록

This paper proposes a DTSA(Detection Technique against a Sybil Attack) protocol so that it can provide vehicles with the secure information for the road situation and the traffic flow among vehicles and by detecting a Sybil attack. This DTSA uses SKC(Session Key based Certificate) to verify the IDs among vehicles, which generates a vehicle's anonymous ID, a session key, the expiration date and a local server's certificate for the detection of a Sybil attack. In conclusion, this DTSA reduces not only the detection time against a Sybil attack but also the verification time for ID by using a hash function and an XOR operation. Besides, a drivers' privacy can be protected by using an anonymous ID. This DTSA helps drivers drive safely with the reliable information of VANET and reduce traffic accidents.
