Abstract

The invention relates to the technical field of credibility of integrated circuits, and discloses a testing vector generating method for effectively activating hardware trojan horses. The method is high in purposiveness, low in testing cost, high in testing efficiency and capable of more effectively activating the hardware trojan horses and has certain actual meaning and reference value for manifesting the hardware trojan horses and analyzing bypass signals, and generated testing sequences are more simplified. In order to achieve the advantages above, according to the adopted technical scheme,the testing vector generating method based on the variation analysis for effectively activating the hardware trojan horses comprises the steps of analyzing the structural characters of a mother circuit, screening out nodes with low activity, utilizing a variation method to execute a variation operation on the circuit structure of the nodes with the low activity to generate high-level variants, and utilizing a functional testing method to screen out testing vectors capable of killing the variants. The method is mainly applied to the safety detection occasion of an integrated circuit.
