| Abstract: | This paper introduces a practice-oriented PKU VANETs privacy-preserving system which aims to the prior location and identity privacy protecting. It proposes the architecture of PKU-VPPS and does some close analysis about that. The proposed system is based on the key technologies such as TP4RS protocol, TC-TPS protocol, VLSP protocol, not only can provide good identity and location privacy protecting for the vehicles, but also can be implemented and deployed well because of its practice-based design and expandability. |
