Information Flow Tracking Methods for Protecting Cyber-Physical Systems against Hardware Trojans -- a Survey. (arXiv:2301.02620v1 [cs.CR])

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, …
