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.
Claims25
A method for non-intrusively detecting counterfeit components in a target computer system, the method comprising:
- collecting 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;
- generating a target EMI fingerprint for the target computer system from the target EMI signals;
- and
- comparing the target EMI fingerprint against a reference EMI fingerprint to determine whether the target computer system contains a counterfeit component.
The method of clam 1, wherein the one or more antennas are positioned inside the chassis of the target computer system.
An apparatus that non-intrusively detects counterfeit components in a target computer system, comprising:
- one or more antennas;
- a collecting mechanism coupled to the one or more antennas, wherein the collecting mechanism is configured to collect target electromagnetic interference (EMI) signals generated by the target computer system using the one or more antennas positioned in close proximity to the target computer system;
- a generating mechanism configured to generate a target EMI fingerprint for the target computer system from the target EMI signals;
- and
- a comparison mechanism configured to compare the target EMI fingerprint against a reference EMI fingerprint to determine whether the target computer system contains a counterfeit component.
A method for non-intrusively detecting counterfeit components in a target computer system, the method comprising:
- collecting target electromagnetic interference (EMI) signals generated by a target component within the target computer system using one or more antennas positioned in close proximity to the target component;
- generating a target EMI fingerprint for the target component from the target EMI signals;
- and
- comparing the target EMI fingerprint against a reference EMI fingerprint associated with the target component within a certified authentic computer system of the same type as the target computer system;
- and
- determining whether the target component within the target computer system is a counterfeit component based on the comparison result.
