Globalization trends in integrated circuit (IC) design are leading to increased vulnerability of ICs against hardware Trojans (HT). Recently, several side channel parameters based techniques have been developed to detect these hardware Trojans that require golden circuit as a reference model, but due to the widespread usage of IPs, most of the system-on-chip (SoC) do not have a golden reference. Hardware Trojans in intellectual property (IP)-based SoC designs are considered as major concern for future integrated circuits. Most of the state-of-the-art runtime hardware Trojan detection techniques presume that Trojans will lead to anomaly in the SoC integration units. In this paper, we argue that an intelligent intruder may intrude the IP-based SoC without disturbing the normal SoC operation or violating any protocols. To overcome this limitation, we propose a methodology to extract the power profile of the micro …
