Abstract

In vehicular ad hoc networks (VANETs), pseudonym change is considered as the vital mechanism to support vehicles' anonymity. Due to the complicated road conditions and network environment, it is a challenge to design an efficient and adaptive pseudonym change protocol. In this paper, a pseudonym change protocol for location privacy preserving (PCP) is proposed. We first present the requirements of pseudonym change in different scenarios. According to variable network states and road conditions, vehicles are able to take different pseudonym change strategies to resist the tracking by global passive adversaries. Furthermore, the registration protocol, authentication protocol, pseudonym issuance protocol, and pseudonym revocation protocol are introduced for the pseudonym management mechanism. As a consequence, it is not feasible for global passive adversaries to track a vehicle for a long time and obtain the trajectory of the vehicle. The analysis results show that the security and performance of PCP are improved compared with the traditional ones.

摘要

在车载自组织网络（VANETs）中，假名变更被视为支持车辆匿名性的关键机制。由于复杂的道路状况和网络环境，设计一种高效且自适应的假名变更协议是一项挑战。本文提出了一种用于位置隐私保护的假名变更协议（PCP）。我们首先阐述了不同场景下假名变更的要求。根据可变的网络状态和道路状况，车辆能够采取不同的假名变更策略来抵御全局被动攻击者的跟踪。此外，针对假名管理机制引入了注册协议、认证协议、假名颁发协议和假名撤销协议。因此，全局被动攻击者长时间跟踪车辆并获取其轨迹是不可行的。分析结果表明，与传统协议相比，PCP的安全性和性能得到了提升。
