Wireless hardware trojan detection

Abstract

Unintended or malicious antennas, or “Hardware Trojans” (HTs) in general, can pose threats to electronic systems if left undetected or unmitigated. The present subject matter can be used to identify a potential presence of HTs in systems as a security mechanism, such as before the HTs can pose any threats. The present subject matter can be integrated as a scanner element in a system that actively checks the environment and provides an indication of a count or presence of antennas or other indicia of HTs. As an example, RADAR scanning can be used to transmit electromagnetic signals and record corresponding reflected signals. These measurements can provide an indication of unique fingerprints of one or more antennas embedded in the captured signal. The measurements can be provided to a trained machine-learning model that can detect a presence of the antennas or HTs, such as identifying a count of antennas present.
