欺骗攻击是无线通信中的一个关键问题，其中系统外部的恶意发送器试图是真实的。作为一种对策，我们提出了一种设备认证方法的基础上使用无线电传播特性（RPC）的位置识别。不依赖于诸如加密技术的信息处理，该方法可以应用于通常具有许多资源限制的感测设备等。我们把攻击取得成功的空间称为“攻击空间”。为了将攻击空间限制在目标系统内部以防止来自外部的欺骗攻击，有必要制定收发器组合与攻击空间之间的关系。在这项研究中，我们考虑两个RPC，接收信号强度比（RSSR）和到达时间差（TDoA），并构建攻击空间模型，同时使用这些RPC。我们以轮胎压力监测系统（TPMS）作为该方法的案例研究，并执行基于无线电波传播模拟的安全性评估。在多种噪声环境下的仿真结果均表明，该方法可以消除远程攻击的可能性。
A spoofing attack is a critical issue in wireless communication in which a malicious transmitter outside a system attempts to be genuine. As a countermeasure against this, we propose a device-authentication method based on position identification using radio-propagation characteristics (RPCs). Not depending on information processing such as encryption technology, this method can be applied to sensing devices etc. which commonly have many resource restrictions. We call the space from which attacks achieve success as the “attack space.” In order to confine the attack space inside of the target system to prevent spoofing attacks from the outside, formulation of the relationship between combinations of transceivers and the attack space is necessary. In this research, we consider two RPCs, the received signal strength ratio (RSSR) and the time difference of arrival (TDoA), and construct the attack-space model which uses these RPCs simultaneously. We take a tire pressure monitoring system (TPMS) as a case study of this method and execute a security evaluation based on radio-wave-propagation simulation. The simulation results assuming multiple noise environments all indicate that it is possible to eliminate the attack possibility from a distant location.
