Non-contact electromagnetic illuminated detection of part anomalies for cyber physical security

摘要

An apparatus for testing, inspecting or screening an electronic device for electrical characteristics, modified or unmodified hardware, or firmware modifications including Malware, Trojans, improper versioning, and the like, includes a transmitting antenna positioned at a distance from the electronic device and a electromagnetic energy receiver or sensor for examining a resulting unintentional derived electromagnetic energy from the electronic device. The receiver collects unintentional RF energy components emitted by the device and includes a processor and executable instructions that perform analysis in a response to the acquired electromagnetic energy input. The characteristics of the collected RF energy may be compared with RF energy characteristics of an exemplary device. The analysis determines one of a modified, unmodified or score of certainty of discerned condition of the device.

主权项

1. An apparatus for determining a state and/or a condition of an unpowered electrical device, comprising:
a waveform generator generating a waveform; a first antenna transmitting electromagnetic energy containing said waveform in a direction of the electrical device; a second antenna receiving artifact(s) unintentionally re-emitted from the electrical device due to excitation thereof with said waveform; one or more processors; and non-transitory computer readable medium containing executable or computational instructions that cause said one or more processors to perform the steps of: developing a signature of the electrical device, wherein said signature contains said artifact(s), analyzing said developed signature, and determining the state and/or condition of the electrical device based on said artifact(s) present in said signature.
