An Attack Resistance Model for Trustworthiness Evaluation in VANET

摘要

Security in vehicular adhoc network (VANET) is a challenging issue. Eavesdropper or attacker breaches security of VANET often due to the dynamicity of vehicular adhoc network with random arrivals and departures of vehicles. In addition, the wireless media also makes VANET vulnerable to an attack [1]. In this paper, a novel dual authentication (DA) algorithm is proposed to counteract few different attacks such as denial of service, sybil attack, replay attack, eavesdropping, and masquerade attack. It is found from the results that the proposed technique is robust against different types of VANET attacks such as sybil attack, replay attack, denial of service, masquerade attack, message suppression attack, and dual authentication failure. Furthermore, a novel trustworthiness evaluation scheme is designed for estimating trustworthiness of each vehicle in VANET. DA algorithm is implemented in JAVA and trustworthiness evaluation is implemented in PHP at the server.
