Stealthy Trojan Detection Based On Feature Analysis Of Circuit Structure

The design methods and the detection methods for Hardware Trojan develop rapidly. Existing trustiness verification methods are effective to obviously malicious HT but no effect on Stealthy Trojan. Stealthy Trojan is an advanced attack form and hard to be detected. In this paper, we analyze the characteristic of stealthy Trojan and propose a static detection method based on feature analysis. The results on ISCAS benchmarks show that the proposed method can detect the Stealthy Trojan node and is convenient to he implanted into other scalable verification framework.
