“…3) Triggers: There are hardware Trojans exploiting don't care conditions for their trigger mechanisms [13], or data patterns in specific memory addresses [14], or even dedicated input images [15]. Some attacks have even more sophisticated triggers which are activated during the design flow, leaving no trigger signal to the possible detection algorithm [16,17].…”

Cyber-physical systems (CPS) provide profitable surfaces for hardware attacks such as hardware Trojans. Hardware Trojans can implement stealthy attacks such as leaking critical information, taking control of devices or harm humans.In this article we review information flow tracking (IFT) methods for protecting CPS against hardware Trojans, and discuss their current limitations. IFT methods are a promising approach for the detection of hardware Trojans in complex systems because the detection mechanism does not necessarily rely on potential Trojan behavior. However, in order to maximize the benefits research should focus more on black-box design models and consider realworld attack scenarios.

“…6) Resources required: For the majority of the Trojans we study, the attacker needs knowledge of the design and access to it (e.g. bitstream [29], netlists [30] or access to the design tools [16,17,31]).…”
