作为物联网的一个有前途的分支,云支持的车联网(CE-IoV)被设想为未来智能交通系统的重要数据传感,交换和处理平台,具有强大的计算和存储能力。CE-IoV为各种新兴应用展示了巨大的前景。为了确保不间断和高质量的服务,车辆应该通过实时VM迁移与自己的VM一起移动,以获得基于位置的实时服务。然而,实时VM迁移可能导致前所未有的位置隐私挑战。在本文中,我们研究了CE-IoV中的位置隐私问题和防御。我们首先提出了两种未开发的虚拟机映射攻击,并因此设计了一个虚拟机标识符替换方案和一个改变同步方案,以保护位置隐私。我们进行模拟,以评估所提出的计划的性能。数值结果表明,所提出的方案是有效的、高效的,并且具有高隐私质量。
As one of the promising branches of the Internet of Things, the cloud-enabled Internet of Vehicles (CE-IoV) is envisioned to serve as an essential data sensing, exchanging, and processing platform with powerful computing and storage capabilities for future intelligent transportation systems. The CE-IoV shows great promise for various emerging applications. In order to ensure uninterrupted and high-quality services, a vehicle should move with its own VM via live VM migration to obtain real-time location-based services. However, the live VM migration may lead to unprecedented location privacy challenges. In this article, we study location privacy issues and defenses in CE-IoV. We first present two kinds of unexplored VM mapping attacks, and thus design a VM identifier replacement scheme and a pseudonym-changing synchronization scheme to protect location privacy. We carry out simulations to evaluate the performance of the proposed schemes. Numerical results show that the proposed schemes are effective and efficient with high quality of privacy.
