Detecting counterfeit electronic components using EMI telemetric fingerprints
First Claim
1. A method for non-intrusively detecting counterfeit components in a target computer system, comprising:
- collecting reference electromagnetic interference (EMI) signals generated by a reference computer system using one or more antennas positioned in close proximity to the reference computer system, wherein the reference EMI signals are generated by the reference computer system while a load script is executed by the reference computer system;
generating a reference EMI fingerprint for the reference computer system from the reference EMI signals;
collecting target EMI signals generated by the target computer system using one or more antennas positioned in close proximity to the target computer system, wherein the target EMI signals are generated by the target computer system while the load script is executed by the target computer system;
generating a target EMI fingerprint for the target computer system from the target EMI signals; and
comparing the target EMI fingerprint to the reference EMI fingerprint to determine whether the target computer system contains a counterfeit component.

Abstract
One embodiment of the present invention provides a system that non-intrusively detects counterfeit components in a target computer system. During operation, the system collects target electromagnetic interference (EMI) signals generated by the target computer system using one or more antennas positioned in close proximity to the target computer system. The system then generates a target EMI fingerprint for the target computer system from the target EMI signals. Next, the system compares the target EMI fingerprint against a reference EMI fingerprint to determine whether the target computer system contains a counterfeit component.

21. A method for non-intrusively detecting counterfeit components in a target computer system, comprising:
-
collecting reference electromagnetic interference (EMI) signals generated by a target component within a reference computer system using one or more antennas positioned in close proximity to the target component, wherein the reference EMI signals are generated by the component while a load script is executed by the reference computer system; generating a reference EMI fingerprint for the target component from the reference EMI signals; collecting target EMI signals generated by the target component within the target computer system using one or more antennas positioned in close proximity to the target component, wherein the target EMI signals are generated by the target component while the load script is executed by the target computer system; generating a target EMI fingerprint for the target component from the target EMI signals; comparing the target EMI fingerprint to the reference EMI fingerprint; and determining whether the target component within the target computer system is a counterfeit component based on the comparison result.
