Kiviat tube based EMI fingerprinting for counterfeit device detection

A non-transitory computer-readable medium storing computer-executable instructions that when executed by at least a processor of a computer cause the computer to:

• apply a power test sequence to a target device;
• obtain a plurality of electromagnetic interference (EMI) signals emitted by the target device while undergoing the power test sequence;
• create a target kiviat tube EMI fingerprint based on at least the plurality of EMI signals obtained;
• compare the target kiviat tube EMI fingerprint to a reference kiviat tube EMI fingerprint from a reference device based on the power test sequence to determine whether the target device and the reference device are of the same type;
• and
• generate a signal to indicate a counterfeit status of the target device based at least in part on a result of the comparison.

A computing system, comprising:

• a processor;
• a memory operably connected to the processor;
• a radio operably connected to the processor and memory;
• a non-transitory computer-readable medium operably connected to the processor and memory and storing computer-executable instructions that when executed by at least the processor cause the computing system to:
• apply a power test sequence to a target device;
• obtain, through the radio, a plurality of electromagnetic interference (EMI) signals emitted by the target device while undergoing the power test sequence;
• create a target kiviat tube EMI fingerprint based on at least the plurality of EMI signals obtained;
• compare the target kiviat tube EMI fingerprint to a reference kiviat tube EMI fingerprint from a reference device to determine whether the target device and the reference device are of the same type;
• and
• generate a signal to indicate a counterfeit status based at least in part on a result of the comparison.
