A novel technique for defending hardware Trojan circuit
Hardware security to ensure trust in IC has emerged as important research topic in recent years, several Trojan detection approaches have been developed to prevent the damages caused by Trojans, making Trojan insertion more and more difficult. This paper design Trojans use a novel technique, which can avoid activate Hardware Trojan in testing time. The simulation results on s38584 benchmark demonstrate that, with a negligible area overhead and power consume, our proposed method can significantly reduce the probability of Trojan detection.
