Sybil Attacks Detection in Vehicular Ad Hoc Networks

Since few years, Vehicular Ad hoc Networks deserve much attention. The development of wireless communication in VANET implies to take into account the need of security for these networks.Vehicular communications play a substantial role in providing safety transportation by means of safety message exchange. Researchers have proposed several solutions for securing safety messages. The significant below against the security of VANET is a Sybil attack. It is an attack in which an original identity of the vehicle is corrupted or theft by an attacker and creates multiple dummy identities for stealing the vehicle. This paper briefly presents various Sybil attack detectionmechanism in VANET.
