Method and system for processing signals of hardware Trojan detection in integrated circuit

Abstract

The invention provides a method and a system for processing signals of hardware Trojan detection in an integrated circuit. The method comprises the following steps of obtaining at least two bypass signals of the to-be-detected integrated circuit; respectively extracting a time domain feature and a frequency domain feature from each bypass signal, and enabling the time domain feature and the frequency domain feature of each bypass signal corresponding to the to-be-detected integrated circuit to form an n-dimension feature vector; converting the n-dimension feature vector into a hardware Trojan risk index by a preset conversion method, wherein the hardware Trojan risk index is used for featuring the degree of the risk of the hardware Trojan in the integrated circuit; comparing the hardware Trojan risk index of the to-be-detected integrated circuit with the preset risk index threshold value, and judging if the hardware Trojan exists in the to-be-detected integrated circuit according to the comparison result. The method and the system have the advantage that the hardware Trojan of the integrated circuit can be detected according to the bypass signals of a plurality of integrated circuits, so the safety of the integrated circuit is improved.

Description

technical field [0001] The invention relates to the technical field of integrated circuit detection, in particular to a signal processing method for hardware Trojan horse detection in integrated circuits and a signal processing system for hardware Trojan horse detection in integrated circuits. Background technique [0002] Due to the globalization of the semiconductor industry, the design process and manufacturing process of integrated circuits have been separated. This business model has greatly weakened the control of IC (integrated circuit, integrated circuit) designers over the manufacturing process, making integrated circuits Increasingly vulnerable to adversary sabotage and malicious modification during the manufacturing phase. Adversaries can add some additional malicious circuits (also known as "hardware Trojan horses") to the chip during the IC manufacturing process. Once these hardware Trojan horses are triggered, they can destroy or destroy the system, leak confid...
