Researchers report on hardware Trojans that are undetectable
(Phys.org) —Worries that the security of integrated circuits used in critical systems by the military and industry can be compromised are all the more real with the release of a research paper titled "Stealthy Dopant-Level Hardware Trojans." The authors are a research team from United States, the Netherlands, Switzerland and Germany. They showed that integrated circuits can be maliciously compromised. The changes elude detection. Even physical inspection of the chip will not pick up the changes made. The authors discussed how they succeeded in modifying a circuit and yet detection mechanisms did not find anything amiss. The authors wrote that "we propose an extremely stealthy approach for implementing hardware Trojans below the gate level."
