Hardware Trojan detection method based on bypass analysis

Abstract

The invention discloses a hardware Trojan detection method based on bypass analysis. The hardware Trojan detection method has the advantages of being free of destructivity, small in implementing expenditure and the like, even in an environment with large measuring noise and technology noise, the detection method can be used for detecting the hardware Trojan with the area smaller than that of an original design circuit by two orders of magnitudes in chips, the signal processing technology which is more applicable than a singular value decomposition algorithm is discussed, the efficiency of detecting the hardware Trojan is improved, the influences of measuring noise can be eliminated by calculating the average value of L power consumption curves of each chip, the technology noise can be eliminated by calculating the average value of the average power consumption curve of N the hardware Trojan chips, P (t; C) is obtained, the calculated amount can be reduced, and time and labor are saved.

Description

[0001] technical field [0002] The invention belongs to the field of computer algorithms, more specifically, the invention relates to a hardware Trojan horse detection method based on bypass analysis. Background technique [0003] For integrated circuit (IC) chips used in security-sensitive systems such as avionics, finance, and transportation, special attention needs to be paid to their reliability, security, and credibility. However, the globalization trend of the integrated circuit industry separates the design of IC chips from the manufacturing process, leading to risks in the outsourcing manufacturing process of IC chips: Some untrustworthy manufacturers may change the original design of IC chips and embed so-called hardware Trojan horses Circuits; these circuits can be activated under specific trigger conditions, thereby leaking sensitive information inside the chip or disrupting the original function of the chip, making the entire system invalid. Because the pot...

[0003] For integrated circuit (IC) chips used in safety-sensitive systems such as avionics, finance, and transportation, special attention needs to be paid to their reliability, safety and credibility . However, the globalization trend of the integrated circuit industry separates the design of IC chips from the manufacturing process, leading to risks in the outsourcing manufacturing process of IC chips: Some untrustworthy manufacturers may change the original design of IC chips and embed so-called hardware Trojan horses Circuits; these circuits can be activated under specific trigger conditions, thereby leaking sensitive information inside the chip or disrupting the original function of the chip, making the entire system invalid. Due to the huge potential harm of hardware Trojans and the difficulty of detection using traditional testing techniques, hardware Trojans are considered to be a major threat to the security of integrated circuits
