Detection and analysis of hardware trojan using scan chain method

Due to the globalization of the Integrated Circuit manufacturing industry and wide use of third party IP in the modern SoCs has opened the backdoor for Hardware Trojan insertion. The detection of Hardware Trojan is challenging because of its very rare activation mechanism and unpredictable change in the functionality of the system. This paper proposes a new hardware Trojan detection scheme using power analysis and experiments the insertion and detection of hardware Trojan using existing scan chain efficiently in ISCAS'89 benchmark circuits.
