Abstract: 
The invention provides a hardware Trojan horse real-time detection system and a design method thereof. The system comprises Trojan probes, a data transmission controller and a safety monitoring kernel. The Trojan probes acquire voltage bypass signals on power supply constraint lines inside an integrated circuit chip, and transmit the voltage bypass signals to the safety monitoring kernel for Trojan detection through the data transmission controller. The method comprises the following steps: the Trojan probes are implanted on the integrated circuit chip at the initial design stage to establishthe data transmission controller; a principal component analysis method is used to optimize the number of the Trojan probes and the optimal coordinates of the Trojan probes are obtained; a third-partyIP core is designed and integrated on the integrated circuit chip layout with the Trojan probe optimal coordinates; a security monitoring kernel is established to monitor the working state of IP corein real time; the abnormal behavior is identified by a support vector machine classification algorithm and the IP core with the Trojan is detected. The invention can detect and locate the IP core containing the Trojan in real time, and can find the Trojan behavior triggered under the low probability condition.
