Hardware Trojan Detection Based on DCVSL

Aimed at detecting hardware Trojans(HTs), the characteristics of CMOS circuits are analyzed, noncomplementary inputs of DCVSL(Differential Cascade Voltage Switch Logic) caused by the active HT result in abnormal short-circuit current. A hardware Trojan detection method based on inherent feature of DCVSL and average dynamic circuit current is proposed. By HSPICE Mento carlo simulation circuit in which we use a C432 standard circuit with a small hardware Trojan as a test circuit, we detecte the existence of Trojan in the circuit, and verify the validity of the method.
