A New Hardware Trojan Design: Distinguishing Between Trigger Inputs and Functional Inputs Is Difficult: Work-in-Progress
Minghui Ge, Ying Zhang, Sen Li, Jiaqi Yao, Zhiming Mao, Xin Chen · 2020
In this paper, we propose a new Hardware Trojan Design. This design makes all HT trigger inputs have the same impact as functional inputs on output signals. It is difficult to distinguish between trigger inputs and functional inputs. Simultaneously, trigger inputs will not be identified as redundant inputs. This approach can defeat the existing detection methods which identify weakly-affecting and redundant trigger inputs across multiple sequential levels. The proposed HT has stealthiness and general applicability.
