Assignee:

NOKOMIS, INC. - Charleroi PA

International Classification:

H04L 29/06

Abstract:

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.
