Rare-vector-sequence-activated lossless detection method for hardware Trojans in integrated circuits

The invention relates to a rare-vector-sequence-activated lossless detection method for hardware Trojans in integrated circuits. The method comprises the following steps of: providing corresponding testing environments for integrated circuits to be tested; producing rare vector sequences for the integrated circuits to be tested; and exciting the integrated circuits to be tested by using the rare vector sequences, testing whether the characteristic parameters and functional roles of the integrated circuits to be tested are abnormal or not, and detecting the integrated circuits implanted with the hardware Trojans and recording breaking manners if the characteristic parameters and functional roles of the integrated circuits to be tested are abnormal. Based on the rare-vector-sequence-activated lossless detection method for the hardware Trojans in the integrated circuits, the integrated circuits implanted with the hardware Trojans can be detected before entering an application system, so that the application system is prevented from being threatened by the hardware Trojans, and the safety of key equipment in important systems is guaranteed.
