Who Is Charging My Phone? Identifying Wireless Chargers via Fingerprinting
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.Comment: Sorry, the content of this paper has to be revised a lot, so we
decided to withdraw it firs
