Hardware Trojan horse detection method and hardware Trojan horse detection system based on test vectors

Abstract

The invention discloses a hardware Trojan horse detection method and a hardware Trojan horse detection system based on test vectors. The method includes receiving reversal information and coverage information of each circuit node in an integrated circuit; selecting circuit nodes as candidate Trojan horse nodes, wherein the reversal information and the coverage information of the circuit nodes meet preset low reversal conditions and preset low coverage conditions respectively; selecting final test vectors from the test vectors according to the reversal information of each candidate Trojan horse node and combined reversal information of each group of candidate Trojan horse nodes; respectively applying the final test vectors to the input end of the integrated circuit, and performing Trojan horse detection on the integrated circuit. By the method and the system, whether or not the integrated circuit contains hardware Trojan horses can be quickly and accurately detected without damage to the integrated circuit.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a hardware Trojan horse detection method and system based on test vectors. Background technique [0002] With the rapid development and wide application of integrated circuits (ICs, Integrated Circuits), the detection of hardware Trojan Horses (Hardware Trojan Horses) maliciously embedded in integrated circuits has become more and more important. Hardware Trojans are malicious circuits implanted into integrated circuits, which can implement destructive functions or leak secret information inside integrated circuits under specific trigger activation conditions, posing a great threat to the security of integrated circuits. [0003] The detection method of the hardware Trojan has physical detection. Physical inspection takes the chip through corrosion and peeling, and uses scanning electron microscope, electronic probe and other equipment to restore the chip to the layout, and ...
