Guided Electromagnetic Wave Technique for IC Authentication.

Area of Science:

• Electrical Engineering
• Materials Science
• Computer Engineering

Background:

• Counterfeiting of integrated circuits (ICs) poses significant risks to electronics manufacturers, system integrators, and end-users.
• Existing detection and avoidance methods for IC counterfeiting often lack efficiency, cost-effectiveness, or noninvasive capabilities.

Purpose of the Study:

• To introduce and evaluate a novel guided radiofrequency (RF) wave technique for authenticating integrated circuits (ICs).
• To develop a noninvasive, efficient, and low-cost method for detecting counterfeit ICs by leveraging their unique electromagnetic signatures.

Main Methods:

• Utilizing guided electromagnetic (EM)/radiofrequency (RF) waves to probe the response of ICs.
• Extracting manufacturing-based process variations from the measured IC responses to generate a unique identifier or signature.
• Performing experiments on field-programmable gate array (FPGA) boards of the same family to validate the approach.

Main Results:

• The guided RF wave technique successfully generated unique signatures for ICs based on their inherent manufacturing variations.
• Post-processing of measurement results allowed for statistical quantification of the authentication technique's error probability.
• Experimental validation demonstrated the feasibility of using EM/RF responses for IC authentication.

Conclusions:

• The guided RF wave technique presents a robust and promising solution for IC authentication, effectively addressing the challenge of counterfeiting.
• This noninvasive method offers an efficient and low-cost alternative for verifying the authenticity of integrated circuits.
• The ability to extract unique IC signatures from EM/RF responses paves the way for enhanced security in electronic supply chains.
