RSU Beacon Aided Trust Management System for Location Privacy-Enhanced VANETs

In VANETs, the decision accuracy of event message under location privacy-enhanced scheme, fast forwarding falsification message, and collusion attacks are all knotty problems that arise in event trust management. Without precisely decision making on event message may endanger the whole transportation system even threat the human life. In addition, the decision delay is another critical issue of traffic safety. The time interval of decision waiting even been the critical accident response time. In this paper, we propose a RSU beacon aided trust management system, which aims to thwart internal attackers accurately under privacy-enhanced VANETs.
