联网车辆利用无线接口广播其运动状态信息，以提高交通安全和效率。在接收器上验证其运动声明（位置和速度）以检测欺骗攻击至关重要。现有方法通常需要多个合作分布式验证器，这不适用于车载网络。在这项工作中，我们提出了一种基于到达角（Angle-of-Arrival）和到达频率（Frequency-of-Arrival）的安全运动验证方案，通过利用环境中的机会信号反射路径创建多个虚拟验证器，该方案只需要一个验证器。我们从理论和现实道路拓扑结构两方面分析了我们方案的安全性。我们还在校园环境中用两辆车进行了实际实验，结果表明我们的方案能在低相对速度的车辆网络中准确检测到虚假的运动声称。
Connected vehicles leverage wireless interfaces to broadcast their motion state information for improved traffic safety and efficiency. It is crucial for their motion claims (location and velocity) to be verified at the receivers to detect spoofing attacks. Existing approaches typically require multiple cooperative distributed verifiers, which is not applicable to vehicular networks. In this work, we propose a secure motion verification scheme based on Angle-of-Arrival and Frequency-of-Arrival that only requires a single verifier, by exploiting opportunistic signal reflection paths in the environment to create multiple virtual verifiers. We analyze the security of our scheme both theoretically and under realistic road topology. We also carry out real-world experiments with two vehicles in a campus environment, and results show that our scheme can accurately detect false motion claims in a low relative speed vehicular network.
