| titleOfInvention | Hardware Trojan horse detection method based on time window self-comparison |
| abstract | The invention discloses a hardware Trojan horse detection method based on time window self-comparison, which mainly comprises three parts: and (3) performing superposition self-comparison on current data in the time window region of the circuit to be detected, performing data post-processing on the selected current result, and realizing a gold-free model detection method. The detection method based on time window self-comparison utilizes the characteristics that process angles of different chips are different and the process angle of the same chip is the same, and can effectively overcome the influence of process fluctuation by selecting the current values of different time window intervals of the transient current of the same chip in the same circuit state and carrying out comparative analysis. In addition, the invention also utilizes the advantage of the Mahalanobis distance to carry out data post-processing on the time window current result through the Mahalanobis distance, increases the distinguishing degree of the influence of the hardware Trojan on the circuit bypass parameters, and further improves the Trojan detection sensitivity. Finally, the method can realize Trojan horse detection under the condition that no golden model reference circuit is used as reference, solve the problem that the golden model reference circuit is excessively dependent in the Trojan horse detection process, and improve the Trojan horse detection efficiency. |
