Vehicular Ad-hoc NETworks (VANETs) are very likely to be emerged in the coming years. This paper is to provide privacy in VANET using shared distributed key management. In shared key management, a short group signature scheme is used to facilitate the revocation of malicious vehicles and heterogeneous security policies. In this framework, Road Side Unit (RSU) acts as the key distributor. A new problem encountered is that a RSU may misbehave. A secure key distribution protocol is used to detect such misbehaved RSUs. The protocol guarantees the traceability of compromised RSUs and malicious vehicles.
