摘要: 针对车辆自组网(VANETs)中的身份和位置隐私保护问题,提出一个面向实用的VANETs隐私保护系统PKU-VPPS,给出该系统的体系架构设计并进行分析和研究。PKU-VPPS系统以TP4RS协议、TC-TPS协议、VLSP协议等为关键技术支撑点,不仅具有对车辆身份隐私和位置隐私进行安全保护能力,还具备良好的实际部署能力和可扩展能力。

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.

Key words: Vehicular Ad Hoc Networks(VANETs), privacy-preserving, message authentication, traceability, TP4RS protocol
