Problems solved by technology

However, in the process of using side channel analysis technology to detect hardware Trojan horses, chips and detection equipment will be affected by external and system internal noise, and the existence of noise will weaken or even submerge the influence of hardware Trojan horses on circuits, which makes the detection of hardware Trojan horses difficult. Yield is greatly reduced

Embodiment Construction

[0036]Aiming at the relatively large noise problem in the hardware Trojan test process, the present invention proposes a hardware Trojan detection optimization method based on HHT noise reduction. The method has excellent adaptability, and while absorbing the multi-resolution advantages of wavelet transform, It overcomes the problem of artificially selecting wavelet bases in wavelet transform. The Hilbert marginal spectrum is obtained through the Hilbert transform, which increases the flexibility and effectiveness of signal analysis. According to the amplitude-frequency characteristics, the high-frequency noise can be accurately located, the high-frequency noise can be filtered out, and the useful information of the side channel data can be retained to a large extent. Therefore, the contribution rate of the feature information of the hardware Trojan horse is increased, and the detection accuracy of the hardware Trojan horse is further improved. This method can be used in the f...

Abstract

The present invention relate to the field of trusted willingness technology for integrate circuits, In order to realize the filtering of high frequency noise and improve the contribution rate of hardware Trojan horse characteristic information, the hardware Trojan horse detection optimization method based on HHT noise reduction comprises the following steps: 1, decomposing the side channel data into N eigenmode function components imfi, i=1... N by using EMD; 2, carrying out Hilbert Hilbert transform on that IMF component of each eigenmode function to obtain the Hilbert marginal spectrum of the IMF component, and determining the effective frequency distribution interval of the original data; 3, if the marginal spectral energy of the IMF component is concentrated outside the effective frequency distribution interval, the IMF component is a noise sequence; Step 4: After removing the IMF component dominated by noise, the Hilbert marginal spectrum of the reconstructed signal after noise reduction is obtained, and the recognition of the hardware Trojan horse is carried out by means of the Mahalanobis distance. The invention is mainly applied to design and manufacture occasions.
