Outsourcing of IC fabrication components has initiated the potential threat of design tempering using hardware Trojans and also has drawn the attention of government agencies and the semiconductor industry. The added functionality, known as hardware Trojan, poses major detection and isolation challenges. This paper presents a hardware Trojan detection technique that magnifies the detection sensitivity for small Trojan in power-based side-channel analysis. A scan segmentation approach with a modified LOC test pattern application method is proposed so as to maximize dynamic power consumption of any target segment. The proposed architecture allows activating any target segment of scan chain and keeping others freeze which reduces total circuit switching activity. This helps magnify the Trojan’s contribution to selected segment by reducing dynamic power consumption. Experimental results for ISCAS89 benchmark circuit demonstrate its effectiveness in side-channel analysis. |
