Embodiment Construction

[0039] Complete technical scheme of the present invention is as follows:

[0040] figure 1 It is a flow chart of a hardware Trojan horse side channel detection method based on electromagnetic and electric current, and the method mainly includes the following steps:

[0041] (1) Perform side-channel tests on all the chips to be tested, and collect side-channel information of the chips to be tested: use the side-channel collection platform to collect the electromagnetic information and current information leaked by the circuit in the working state multiple times.

[0042] (2) Preprocessing the side channel information of all chips under test: smoothing and filtering the electromagnetic information and current information of all chips under test to obtain smooth electromagnetic and current side channel information. Divide the electromagnetic information and current information of the chip to be tested into n intervals on average, and perform derivation processing on the electrom...

Abstract

The invention relates to the technical field of integrated circuit dependability testing, and provides a hardware Trojan side channel detection method based on the electromagnet and the electric current to achieve the detection of hardware Trojans. The hardware Trojan side channel detection method based on the electromagnet and the electric current comprises the steps that 1, the side channel tests of the to-be-measured chips are conducted; 2, pretreatments are performed on the side channel information of all the to-be-measured chips; 3, the proportion coefficient matrix R1xn of the electromagnetic differential information and the leaked electric current information of all the to-be-measured chips are determined; 4, the discrimination is conducted on the differences of the proportion coefficient matrix for part of the to-be-measured chips; 5, the discrimination is conducted on the hardware Trojan chips of the to-be-measured chips; 6, the online difference recognitions are conducted on the hardware Trojans. The hardware Trojan side channel detection method is mainly used in dependability detection tests of integrated circuits.

Description

technical field [0001] The invention relates to the technical field of integrated circuit trustworthiness detection, in particular to a hardware Trojan horse side channel detection method based on the corresponding relationship between electromagnetic and electric current.
