A trust and reputation management framework for VANETs (Vehicular Ad Hoc NETworks) is proposed. In the framework, a similarity mining technique is used for identifying similar messages or similar vehicles. And a reputation evaluation algorithm is proposed for evaluating a new vehicle's reputation based on the similarity theory. Similarities from different recommenders are used as weights for computing a vehicle's recommendation based reputation. An updating algorithm for reputations is proposed in the framework. The framework is applied to decide whether a message is trustworthy when a vehicle receives an event message.
