Abstract—VANETs are the academic and industry research priorities in recent years. Security and privacy-preserving have become a bottleneck for VANETs’ future developing. There are few literatures about the architecture of VANETs privacy-protecting system. In this paper, we introduce a practical VANETs Privacy-Preserving System which aims to the prior location and identity privacy protecting. We propose the architecture and do some close analysis about that. The proposed system is based on the key technologies such as TP4RS protocol, and achieves some good features: the system not only can provide good identity and location privacy protecting for the vehicles, but also can be implemented and deployed well because of its practical design and expandability. To the best of our knowledge, our scheme is the first architecture design scheme for the practical VANETs privacy protecting system.
