Detecting Trojan Circuits with On-Chip Temperature Sensors
ECE Associate Professor Marvin Onabajo and Professor Yong-Bin Kim were awarded a patent for creating a "method to use on-chip temperature sensors for detection of Trojan circuits".
Abstract Source: USPTO
A method for detecting a malicious circuit on an integrated circuit chip is provided, in which temperature sensors are thermally coupled to primary circuitry on the chip. Signals obtained from the temperature sensors are indicative of power dissipation by the primary circuity on the integrated circuit chip. Comparison with a baseline signal, or golden signature, can be used to determine the presence of a malicious circuit in the primary circuitry.
