Nonlinear analysis for hardware Trojan detection

As an important content of chip security, Hardware Trojan detection has attracted a lot of attention. The existing Hardware Trojan detection methods based on side-channel power consumption are effective. The main existing Hardware Trojan detection methods based on side-channel power consumption analysis mainly concentrate on linear features but ignore the features of Hardware Trojan in nonlinear space. This paper proposes a nonlinear detection method based on side-channel power consumption information, it extracts and magnifies features of Hardware Trojan in nonlinear space and achieves Hardware Trojan detection. The results of experiment show that the nonlinear analysis method proposed in this paper can detect the Hardware Trojan effectively in nonlinear space.
