Hardware Trojan horse detection method and hardware Trojan horse detection system

Abstract

The invention provides a hardware Trojan horse detection method and a hardware Trojan horse detection system. The method includes the following steps: collecting a by-pass signal of a to-be-detected integrated circuit; extracting features of the by-pass signal to form a feature collection; calculating mahalanobis distance values, including a mahalanobis value of a reference integrated circuit and a mahalanobis value of the to-be-detected integrated circuit, of the feature collection; comparing the mahalanobis value of the reference integrated circuit with that of the to-be-detected integrated circuit, and performing hardware Trojan horse detection according to a comparison result. By the hardware Trojan horse detection method and the hardware Trojan horse detection system which have the advantages of simple algorithm and short detection time, distinguishability and efficiency of hardware Trojan horse detection in integrated circuit testing are effectively improved, and any cost for hardware is not generated.

Description

technical field [0001] The invention relates to the field of integrated circuit testing, in particular to a hardware Trojan horse detection method and a hardware Trojan horse detection system. Background technique [0002] With the continuous improvement of integrated circuit manufacturing technology, the cost of establishing and maintaining an integrated circuit manufacturing plant at the forefront of technology is getting higher and higher (today, it takes nearly 30 billions of dollars), which resulted in the separation of the design process and the manufacturing process of the integrated circuit, that is, after the designer of the integrated circuit completes the circuit design, it delivers the final design data to the integrated circuit manufacturing plant, and the manufacturing plant is responsible for the specific processing and production. The above-mentioned status quo has caused the manufacturing process of integrated circuits to be out of the control of the design...

[0004] However, although the above-mentioned hardware Trojan horse detection method has utilized the IC of the integrated circuit DDT and F max There is a linear relationship between them, but it only uses this linear dependence to conduct a simple trend analysis, that is, draw them on a graph as Y-axis and X-axis respectively, and observe whether the data of the integrated circuit under test is offset A baseline trend line is established to determine whether there is a hardware Trojan in the integrated circuit

Although the simple trend analysis of multiple bypass signals by this method can effectively detect some hardware Trojans, it fails to fully mine the correlation between multiple bypass signals, which leads to the identification of hardware Trojans. low rate
