Quote:Is it possible for attackers to equip integrated circuits with hardware Trojans that will not change the area or power consumption of the IC, making them thus indiscernible through power-based post fabrication analysis?
A group of researchers from the National University of Sciences and Technology (Islamabad, Pakistan), the Vienna University of Technology and New York University have proven it is.
They have also demonstrated that hardware Trojans (HTs) can be implanted not only by adding logical gates to the original circuit, but also by identifying and safely removing expendable, redundant gates and embedding malicious circuitry at the appropriate locations.
