In this paper, the authors present a reputation assisted trust management mechanism for Vehicular Ad hoc NETwork (VANET) using privacy preserving trusted group formation. In a VANET, vehicles or road side units can be malicious or malfunction making security essential. A distributed trust management provides a lightweight security alternative to existing security techniques especially in VANET. The trust mechanism framework is based on group formation which is multi step process. Once a group is formed, the group manager tracks the behavior of vehicles and changes their trust value in accordance to its current behavior which is essential in large scale road transportation.
