THE NEW RSU BASED ON SECURE DATA TRANSMISSION AND SYBIL ATTACK DETECTION SYSTEM IN VANET?

In Vehicular Communication, the security system against the attacker is an essential one. Sybil attack is an identity based attack through which the vehicle can successfully masquerades the ID of vehicles to create the wrong destination. The identification of Sybil attacks, determining the number of attackers and eliminating them is a challenging task in vehicular ad hoc Network. The message verification is an approach that is used to detect the Sybil attack in vehicles. This approach did not predict the attackers accurately. To overcome this problem, the paper proposes Diffe-Hellman key algorithm to detect the Sybil attack. The Diffe-Hellman key algorithm monitors and gives the secret key to the vehicles to reach the correct destination in Vehicular Ad Hoc Network. Analytical and simulation experiments result shows that the proposed scheme detects the Sybil attacks in VANET efficiently and robustly with the cost of reasonable overheads.
