论文摘要
随着物联网（IoT）设备的日益普及，对快速和方便的电池充电服务的需求迅速增长。无线充电是这种目的的有前途的技术，其用途已无处不在。但是，充电器和所充电设备之间的近距离不仅使基于接近和近场通信攻击成为可能，而且还引入了一种新型的漏洞。在本文中，我们建议基于基础充电电路的固有非线性失真效应为无线充电器创建指纹。使用这样的指纹，我们设计了无线系统来检测潜在的短距离恶意无线充电攻击。无线接收到充电过程的待机状态的信号，并将其发送到受信任的服务器，该服务器可以提取指纹并识别充电器。
With the increasing popularity of the Internet of Things(IoT) devices, the demand for fast and convenient battery charging services grows rapidly. Wireless charging is a promising technology for such a purpose and its usage has become ubiquitous. However, the close distance between the charger and the device being charged not only makes proximity-based and near field communication attacks possible, but also introduces a new type of vulnerabilities. In this paper, we propose to create fingerprints for wireless chargers based on the intrinsic non-linear distortion effects of the underlying charging circuit. Using such fingerprints, we design the WirelessID system to detect potential short-range malicious wireless charging attacks. WirelessID collects signals in the standby state of the charging process and sends them to a trusted server, which can extract the fingerprint and then identify the charger.
