本文介绍了UnSpoof，一种超宽带定位系统，可以通过几个协作被动接收锚点检测和定位距离欺骗标签。我们提出了一种新的方案，使被动接收锚点能够通过监听标签和一个主动锚点之间的标准双向测距信息来推断其飞行时间（ToF）和到达时间差（TDoA）。我们的ToF公式可用于精确定位诚实标签，并检测错误报告其时间戳的距离欺骗标签。此外，我们的TDoA配方支持欺骗威慑定位，可用于跟踪和逮捕恶意标签。我们的实验评估显示，基于tof的诚实标签定位有30厘米$\text {75}{\text{th}}$百分位误差，而基于tdof的欺骗标签定位有一个亚米误差。我们成功地检测了锚的凸壳内部的距离减小和扩大攻击以及外部的优雅退化。此外，我们还展示了锚点不规则几何形状的影响，并邀请研究人员和实践者通过我们的开源建模软件对他们感兴趣的锚点拓扑进行实验。
This article presents UnSpoof, an ultrawideband localization system that can detect and localize distance-spoofing tags with a few collaborative passively receiving anchors. We propose novel formulations that enable passively receiving anchors to deduce their time-of-flight (ToF) and time-difference-of-arrival (TDoA) just by overhearing standard two-way ranging messages between the tag and one active anchor. Our ToF formulation can be used to precisely localize an honest tag, and to detect a distance-spoofing tag that falsely reports its timestamps. Additionally, our TDoA formulation enables spoofing deterrent localization, which can be used to track down and apprehend a malicious tag. Our experimental evaluation shows a 30-cm $\text {75}{\text{th}}$ percentile error for ToF-based honest tag localization and a submeter error for TDoA-based localization for spoofing tags. We demonstrate successful detection of distance reduction and enlargement attacks inside the anchors' convex hull and graceful degradation outside. In addition, we show the effects of a nonregular geometry of anchors and invite researchers and practitioners to experiment with anchor topologies of interest to them via our open source modeling software.
