title = "Antisybil: Standing against sybil attacks in privacy-preserved VANET",
abstract = "In this paper, we aim at two conflicting goals, privacy and Sybil {\'y}attacks in Vehicular Ad Hoc NETworks (VANETs). Sybil attack {\'y}refers to impersonation of one physical entity for many, namely {\'y}Sybil nodes. Such attacks may cause dire consequences such as {\'y}traffic jams or even deadly accidents. We leverage pseudonymless {\'y}beaconing in order to {\'y}preserve privacy. To cope with the Sybil {\'y}attack, we put forth a twofold strategy. For scheduled beacons, {\'y}we {\'y}employ TRM (Tamper Resistant Module) to perform a {\'y}lightweight pre-assembly data analysis on beacons whereas {\'y}for {\'y}ERMs (Event Reporting Messages), RSUs distribute {\'y}authorized tokens among benign vehicular {\'y}nodes which in turn {\'y}are consumed to report ERM. Our proposed scheme preserves {\'y}privacy {\'y}in both beacons and ERMs, and offers conditional {\'y}anonymity.{\'y}",
