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. Index Terms—vehicular ad-hoc networks, preserving, message authentication, traceability I. However, before the above attractive applications come into reality, the security and privacy issues should be addressed. Otherwise, a VANET could be subject to many security threats, which will lead to increasing malicious attacks and service abuses. More precisely, an adversary can either forge bogus messages to mislead other drivers or track the locations of the intended vehicles. Therefore, the security and privacy is the key to the VANETs, and has been well-studied in recent years. Since the .
