提高交通系统的安全性是车辆自组网的主要目的。为了提高交通安全性，保证事件消息的可靠性，信任管理的研究越来越受到重视。然而，在这些研究中，很少有人关注的位置隐私，由于信任和匿名之间的天然冲突，这是隐私的基本保护。虽然交通安全仍然是温哥华最重要的要求，但位置隐私对司机来说同样重要，两者都不能忽视。在本文中，我们提出了一个自组织的信任管理系统，旨在阻止内部攻击者发送虚假消息的隐私增强的VANETS。为了评估所提出的系统的可靠性和性能，我们进行了一组模拟下的共谋和非共谋攻击。仿真结果表明，无论是在固定静默期（FSP）还是随机静默期（RSP）位置隐私增强方案下，该系统都具有较强的抗攻击能力。
Improving the safety of transportation system is the main purpose of vehicle ad-hoc networks (VANETs). In order to improve traffic safety and ensure the event messages reliability, more and more researches have been focused on trust management to resolve the problems. However, in these researches, little attention has been paid to the location privacy due to the natural conflict between trust and anonymity, which is the basic protection of privacy. Although traffic safety remains the most crucial requirement in VANETs, location privacy can be just as important for drivers, and neither can be ignored. In this paper, we propose a self-organized trust management system that aims to thwart internal attackers from sending false messages in privacy-enhanced VANETS. To evaluate the reliability and performance of the proposed system, we conducted a set of simulations under collusion and non-collusion attacks. The simulation results show that the proposed system is highly resilient to adversarial attacks, no matter whether it is under a fixed silent period (FSP) or random silent period (RSP) location privacy-enhanced scheme.
