In this paper, the authors 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.
