Vehicular Ad Hoc network (VANET) can offer various services and benefits to VANET users and thus deserves deployment effort. Misusing such network could cause destructive consequences. It is therefore necessary to discourage misbehavior and defend VANET systems against it, in order to ensure correct and smooth operations of the network. In this paper, we propose a defense technique to handle misbehavior in VANETs, caused by either malfunctioning hardware (unintentional) or purposeful attacks. It can be used in both inter-vehicle and vehicle-to-infrastructure communications, where user privacy is highly desirable but adds more complexity to the defense. By employing our misbehavior defense technique, users of the system can opt for allowing occasional or unintentional misbehavior while preventing frequent or disruptive misbehavior.
