Abstract:To ensure that a hardware Trojan remains hidden in a circuit, it is usually necessary to ensure that the trigger signal has a low testability, which has been widely recognized and proven. The most advanced testability-based detection methods are rather slow for large circuits, and the false-positive rate is not as low as that for small circuits. In this paper, a hardware Trojan, through the low testability of the trigger signal and its position characteristics in the circuit, was detected, which greatly improv… Show more
