Implicit Hardware Trojan: Principles and Enabling Methods
Nilanjana Das, Mattis Hasler, Sebastian Haas · 2023
The research community of hardware security has worked hard to develop effective defenses against a range of hardware Trojans (HTs). However, HT design research has consistently advanced faster than HT detection research. In this paper, we describe the concept of implicit hardware Trojan (IHT) design, its properties, enabling methods, and adversarial effects. The IHT advances the field of HT design research. We propose different kinds of multiple IHTs (MIHTs) and classify them in terms of considered logic gates used to design the MIHTs. Results from experiments demonstrate the IHT design’s effectiveness and deceit.
