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.
