Towards a cost-effective hardware trojan detection methodology

Due to the increasing globalization of integrated circuit fabrication, hardware security has emerged as a major issue, necessitating hardware trojan detection mechanisms. Numerous techniques exist, a subset of which we applied to 6 sets of combinational circuits and 2 sets of sequential circuits in order to effectively determine the presence of a hardware trojan. Utilizing only a single type of functional test and a single type of side-channel test, we were able to make determinations about all 6 sets of combinational circuits and 1 of the 2 sets of sequential circuits.
