Patent Images
1. A system for classifying an unknown electronic component comprising:
- an electronic component interface for electrically interfacing with the unknown electronic component;
a sensor adapted to measure a power consumption signal of the unknown electronic component during an idle state via said electronic component interface;
a control unit configured to;
process said power consumption signal of the unknown electronic component measured during said idle state to generate an intrinsic noise signature unique to the unknown electronic component;
retrieve previously-stored information regarding power consumption signals measured during an idle state of a plurality of electronic components;
compare said intrinsic noise signature of the unknown electronic component and said retrieved previously-stored information regarding power consumption signals; and
classify the unknown electronic component based on the comparison of said processed power consumption signal of the unknown electronic component and said retrieved previously-stored information regarding power consumption signals.

Abstract
A system and method of electronic component authentication or component classification can reduce the vulnerability of systems (e.g., satellites, weapons, critical infrastructure, aerospace, automotive, medical systems) to counterfeits. Intrinsic deterministically random property data can be obtained from a set of authentic electronic components, processed, and clustered to create a classifier that can distinguish whether an unknown electronic component is authentic or counterfeit.
