In vehicular networks, moving vehicles are enabled to communicate with each other using inter vehicle communications as well as with Road Side Units (RSUs) in vicinity via roadside-to-vehicle communications. In urban vehicular networks where the privacy, especially the location privacy of the vehicles should be guaranteed vehicles need to be verified in an anonymous manner. A wide spectrum of applications in such a network relies on collaboration and information aggregation among the participating vehicles. Without the identities of participants, such applications are vulnerable to the Sybil attack where a malicious vehicle masquerades as multiple identities, overwhelmingly influencing the result.
