Abstract

The system for detecting hardware trojans in integrated circuits by analyzing the substrate noise generated by the unique physical properties of such an integrated circuit disclosed herein may compare the substrate noise signatures of a subject IC against the noise signature from one or more known good ICs to detect such trojans, and may measure the electromagnetic, current, or voltage noise of an IC as a function of time synchronized with the test sequence. The system may allow for the testing of such substrate noise at multiple points around the IC, and may further comprise a Cypher Block Chain (CBC) technique to incorporate the noise measurements over time into a signature unique to the IC.
