Integrated circuit hardware Trojan horse detection method and system

Abstract

The invention provides an integrated circuit hardware Trojan horse detection method and system. The method includes acquiring bypass information training samples of Trojan horse chips and non Trojan horse chips in the set numbers; performing main component analysis on the bypass information training samples of the non Trojan horse chips to acquire k-dimensional principal eigenvectors; calculating the feature projection of a chip to be detected of bypass information vectors of the chip to be detected on the k-dimensional principal eigenvectors of the non Trojan horse chips and the Trojan horse chip feature projection and non Trojan horse chip feature projection of the bypass information training samples of the Trojan horse chips and non Trojan horse chips on the k-dimensional principal eigenvectors of the non Trojan horse chips respectively; if K< / =3, judging the chip to be detected to be a Trojan horse chip or non Trojan horse chip according to a k-dimensional image; if the k > 3, judging the chip to be detected to be a Trojan horse chip or non Trojan horse chip according to the mahalanobis distance. The method is adaptive to the characteristic of uncertainty of the data dimension, the Trojan horse chip and non Trojan horse chip can be identified accurately, and the integrated circuit pattern identifying capability and efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of hardware safety 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 have become a global trend. In recent years, a new type of hardware attack method against integrated circuit chips 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 generally very difficult to detect. [0003] With the emergence and development of hardware Trojan detection technology...
