【摘要】：針對基于旁路分析的硬件木馬檢測中存在的旁路信號冗余以及高維問題,探究特征選擇方法在去除冗余、降低旁路信號維數(shù)方面的可行性,提出了一種以類內(nèi)類間距離作為可分性判據(jù)的特征選擇方法對旁路信號進(jìn)行預(yù)先處理。首先分析了IC芯片旁路信號的特征選擇問題,然后闡述了基于類內(nèi)類間距離的可分性判據(jù)以及特征選擇搜索算法,最后在FPGA密碼芯片中植入硬件木馬,并基于K-L方法進(jìn)行檢測實驗,通過對旁路信號進(jìn)行特征選擇前后的木馬檢測效果對比發(fā)現(xiàn),該特征選擇方法能有助于分辨出無木馬的"金片"與含木馬芯片之間旁路信號的統(tǒng)計特征差異,更好地實現(xiàn)硬件木馬的檢測。
[Abstract]:Aiming at the redundancy and high dimension of bypass signal in the detection of hardware Trojan horse based on bypass analysis, the feasibility of feature selection in removing redundancy and reducing the dimension of bypass signal is explored. In this paper, a method of feature selection based on the inter-class distance as the criterion of separability is proposed to preprocess the by-pass signal. In this paper, the feature selection problem of bypass signal in IC chip is analyzed, then the separability criterion based on inter-class distance and the feature selection search algorithm are described. Finally, a hardware Trojan is implanted in the FPGA cipher chip. And based on K-L method, the detection results of Trojan horse before and after feature selection of bypass signal are compared and found. The method of feature selection can help to distinguish the statistical characteristics of the bypass signal between the trojaned "gold chip" and the trojaned chip, and to better realize the detection of the hardware Trojan horse.
