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.

First claim

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

1. An electronic component classification system for classifying a plurality of electronic components, the electronic component classification system comprising:
an electronic component interface to electrically interface with the plurality of electronic components;
a sensor configured to measure a power consumption signal of each of the plurality of electronic components via the electronic component interface and store information regarding the power consumption signal of each of the plurality of electronic components in memory;
a destructive classification system configured to destructively classify at least one of the plurality of electronic components, the destructive classification system storing information regarding the classification of the at least one of the plurality of electronic components in memory associated with the previously-stored information regarding the power consumption signal of the at least one of the plurality of electronic components; and
a control unit configured to non-destructively classify the remaining plurality of electronic components by comparing the previously-stored information regarding the power consumption signal of the at least one destructively classified electronic component to the previously-stored information regarding the power consumption signal of each of the remaining plurality of electronic components.

2. The electronic component classification system of claim 1 wherein the control unit is configured to classify the remaining plurality of electronic components by building a classifier based on the information regarding the power consumption signal of the at least one destructively classified electronic component stored in memory and classifying the remaining plurality of electronic component using the classifier and the power consumption signals of each of the plurality of electronic components.

3. The electronic component classification system of claim 1 wherein the control unit is configured to identify unauthentic components for quarantine.

4. The electronic component classification system of claim 1 wherein the plurality of electronic components belong to a purported component class and wherein the destructive classification system is configured to destructively classify the at least one electronic component as belonging to the purported component class.

5. The electronic component classification system of claim 4 wherein the control unit is configured to classify additional electronic components that purport to belong to the purported component class by comparing the previously-stored information regarding the power consumption signal of the plurality of electronic components to information regarding the power consumption signal of each of the additional electronic components.

6. The electronic component classification system of claim 1 wherein the plurality of electronic components are a purported type of component and wherein the destructive classification system is configured to destructively classify the at least one electronic component as the purported type of component.

7. The electronic component classification system of claim 6 wherein the control unit is configured to classify additional electronic components that purport to be the purported type of component by comparing the previously-stored information regarding the power consumption signal of the plurality of electronic components to information regarding the power consumption signal of each of the additional electronic components that purport to be the purported type of component.

8. The electronic component classification system of claim 1 wherein the electronic component interface is configured such that the plurality of electronic components are temporarily and sequentially installable one at a time into the electronic component interface.

9. The electronic component classification system of claim 1 wherein the destructive classification system is configured to destructively classify the at least one electronic component as authentic and wherein the control unit is configured to non-destructively classify the remaining plurality of electronic components as authentic by comparing the previously-stored information regarding the power consumption signal of the at least one destructively classified authentic electronic component to the previously-stored information regarding the power consumption signal of each of the remaining plurality of electronic components.

10. An electronic component classification system for classifying a plurality of electronic components, the electronic component classification system comprising:
an electronic component interface to electrically interface with the plurality of electronic components;
a sensor configured to measure a noise signal of each of the plurality of electronic components via the electronic component interface and store information regarding the noise signal of each of the plurality of electronic components in memory;
a destructive classification system configured to destructively classify at least one of the plurality of electronic components, the destructive classification system storing information regarding the classification of the at least one electronic component in memory associated with the previously-stored information regarding the noise signal of the at least one electronic component; and
a control unit configured to non-destructively classify the remaining plurality of electronic components by comparing the previously-stored information regarding the noise signal of the at least one destructively classified electronic component to the previously-stored information regarding the noise signal of each of the remaining plurality of electronic components.

11. The electronic component classification system of claim 10 wherein the control unit is configured to classify the remaining plurality of electronic components by building a classifier based on the information regarding the noise signal of the at least one destructively classified electronic component stored in memory and classifying the remaining plurality of electronic component using the classifier and the noise signals of each of the plurality of electronic components.

12. The electronic component classification system of claim 10 wherein the control unit is configured to identify unauthentic components for quarantine.

13. The electronic component classification system of claim 10 wherein the plurality of electronic components belong to a purported component class and wherein the destructive classification system is configured to destructively classify the at least one electronic component as belonging to the purported component class.

14. The electronic component classification system of claim 13 wherein the control unit is configured to classify additional electronic components that purport to belong to the purported component class by comparing the previously-stored information regarding the noise signal of the plurality of electronic components to information regarding the noise signal of each of the additional electronic components.

15. The electronic component classification system of claim 10 wherein the plurality of electronic components are a purported type of component and wherein the destructive classification system is configured to destructively classify the at least one electronic component as the purported type of component.

16. The electronic component classification system of claim 15 wherein the control unit is configured to classify ad
