Abstract

A hardware Trojan horse detection method based on a chip temperature field effect is disclosed. Based on the chip temperature field effect, a chip to be detected is firstly subjected to grid partition, then a test vector is inputted into the chip to be detected, the temperature in each grid of the chip during operation is measured to obtain a heat map of the chip, and the heat map is used for a neural network to identify Trojan horse information of the heat map. In addition, heat map sets of chips to which a Trojan horse is inputted and chips to which no Trojan horse is inputted are utilized to train the neural network, and then the trained neural network is utilized to detect the chip to be detected so as to determine whether a Trojan horse is inputted to the chip to be detected. The method has characteristics of a high detection rate and easy implementation, and can ensure correct detection of a hardware Trojan horse.

Description

technical field [0001] The invention belongs to the technical field of chip hardware security, and in particular relates to the design of a hardware Trojan horse detection method based on the chip temperature field effect. Background technique [0002] Trojan horse implantation is a certain circuit structure maliciously inserted into an integrated circuit, which can change circuit functions, leak circuit information, or cause circuit denial of service, etc., which poses a great threat to hardware security. However, because the hardware Trojan occupies a small area and is inactive for a long time, it is almost impossible to detect. [0003] At present, the common methods proposed by the academic circles for hardware Trojan detection include logic testing, test design, side channel analysis, reverse engineering, and the like. The test design is to insert an extra test circuit into the chip in order to detect the hardware Trojan horse. These test circuits can only detect hard...
