Abstract

The invention provides an integrated circuit hardware Trojan detection method and system. The integrated circuit hardware Trojan detection method comprises obtaining the bypass information data of chips to be detected; extracting a plurality of sample chips from the chips to be detected to be clustered into two chip clusters and determining corresponding cluster centers; extracting several sample chips from the two clusters for reverse engineering hardware Trojan analysis and determining the types of the several sample chips; determining the types of the other chips to be detected according to the Euclidean distance between the other chips to be detected and the two cluster centers, wherein the other chips are except the cluster chips. According to the integrated circuit hardware Trojan detection method and system, the hardware Trojan detection work of the chips to be detected can be achieved without a large amount of integrated circuit hardware Trojan reverse engineering analysis work and accordingly the integrated circuit hardware Trojan detection efficiency is improved and the cost in the detection process is reduced.

Description

technical field [0001] The invention relates to the technical field of integrated circuit detection, in particular to a method and system for detecting an integrated circuit hardware Trojan horse. Background technique [0002] With the development of semiconductor technology and manufacturing technology, hardware outsourcing design and tape-out has become a global trend. In recent years, a new type of hardware attack method against integrated circuits has emerged, called "hardware Trojan horse". Hardware Trojans mainly refer to artificially maliciously adding some illegal circuits or tampering with original design files in the process of IC design and manufacturing, thereby leaving "time bombs" or "electronic backdoors", etc., opening the door for subsequent attacks. Once a hardware Trojan is artificially and covertly inserted into a complex chip, it is very difficult to detect. Its harm mainly includes stealing important information of the chip, affecting circuit performanc...
