A hardware Trojan horse detection optimization method based on EMD noise reduction data preprocessing

Abstract

The invention relates to the technical field of integrated circuit credibility, and provides a hardware Trojan horse detection optimization method, which not only can better keep the smoothness characteristic of a low-frequency part of data, but also can keep the useful information of a high-frequency part of side channel data to a greater extent, thereby effectively keeping the characteristics ofa hardware Trojan horse and further improving the hardware Trojan horse detection precision. Therefore, the technical scheme adopted by the invention is as follows: the hardware Trojan horse detection optimization method based on EMD noise reduction data preprocessing Includes: determining a demarcation point of the noise dominant mode and the signal dominant mode by combining the characteristics of the autocorrelation function of each intrinsic mode function IMF, performing noise reduction on the high-frequency mode function by adopting a threshold selection denoising method, and performingSavitzky-on the low-frequency mode function by adopting a Savitzky-method; and filtering by using a Golay filter, reconstructing by using an IMF component to obtain noise-reduced data, and judging the hardware Trojan horse by using a Mahalanobis distance. The method is mainly applied to the trustworthiness detection occasion of the integrated circuit.

Problems solved by technology

However, in the process of using the bypass signal analysis technology to detect the hardware Trojan, the chip and the detection equipment will be affected by the external noise and the internal noise of the system. The existence of noise will weaken or even submerge the influence of the hardware Trojan on the circuit, which makes the hardware Trojan The detection rate is greatly reduced
