Abstract: In the existing hardware Trojan detection methods, there is problem of low detection rate. Therefore, a cost-sensitive hardware Trojan detection was proposed. By analyzing the structural and signal features of Trojan circuits, an 11 dimensional Trojan feature vector was established. A Trojan feature expansion algorithm based on Borderline-SMOTE was proposed, which effectively expanded the Trojan sample information in the training set. Based on PSO algorithm, the parameters of SVM model were optimized, and a cost-sensitive classification model was established. 17 benchmark circuits from the Trust-Hub were used to verify the efficacy of the proposed approach. Among them, the TPR of 16 benchmark circuits is 100%, and the average TNR is as high as 99.04%. Compared with other existing methods, the detection rate of Trojan is improved greatly.

近些年來,,隨著半導體產(chǎn)業(yè)的蓬勃發(fā)展,集成電路(IC)設計和制造的外包已成常態(tài),,這為惡意的第三方供應商在IC中植入硬件木馬提供了機會,。硬件木馬一旦被激活,可能導致IC功能的改變、泄露內(nèi)部信息,、降低電路可靠性,,甚至使芯片失效??紤]到木馬電路為硬件安全帶來的巨大威脅,,硬件木馬檢測的研究一直在積極進行。然而,,硬件木馬的設計和檢測相互促進,、同步發(fā)展,即一種新的檢測方法被提出后,,攻擊者會立即設計出一種新的硬件木馬,,以規(guī)避該檢測方法。因此,,如何實現(xiàn)對未知硬件木馬的有效檢測是一個亟待解決的問題,。鑒于此問題,一種基于機器學習的硬件木馬檢測方法被提出,,通過分析和提取木馬電路的特征,,建立硬件木馬特征數(shù)據(jù)庫,應用機器學習模型進行分類器的訓練,,使用訓練好的分類器檢測門級網(wǎng)表中可能被植入的硬件木馬,。該方法不需要純凈的黃金網(wǎng)表作為參考,當新類型的硬件木馬出現(xiàn)時,,可以通過更新特征數(shù)據(jù)庫擴大檢測范圍,,實現(xiàn)對新型木馬的覆蓋,因而得到廣泛的研究,。
