ELECTRONIC COMPONENT CLASSIFICATION
First Claim
Patent Images
1. A method of classifying an unknown electronic component comprising:
- temporarily installing a plurality of known electronic components into a component interface of an electronic component authentication system for signal measurement;
measuring, during an idle state, a noise signal for each of the plurality of known electronic components via the component interface;
building a classifier based on the noise signals of the plurality of known electronic components; and
classifying the unknown electronic component using the classifier.

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.
