Abstract

The invention belongs to the field of third-party IP core trustworthiness verification. In order to propose a new method for hardware Trojans, improve the detection efficiency of hardware Trojans, realize distributed detection and effectively solve the limitation problem of reference models in the actual testing process, and further promote IP Practical progress of nuclear security vulnerability detection. For this reason, the technical solution that the present invention adopts is, based on the hardware Trojan side channel analysis method of multiple IP cores, determine the mutual derivation relationship between multiple IP cores according to the side channel analysis technology, when the side channel information of one of the IP cores is consistent with the ideal If there is a discrepancy in the side channel information, it is determined that there is a hardware Trojan horse. The invention is mainly applied to the occasion of IP core trustworthiness.

Embodiment Construction

[0027] Aiming at the problem that the coverage rate of simulation verification is difficult to reach 100% and formal verification can only be limited to small-scale circuits, the present invention proposes a method for detecting hardware Trojans using the idea of ​​side channel analysis, and determines the method based on side channel analysis technology The mutual deduction relationship between multiple IP cores, when the side channel information of one of the IP cores is different from the ideal side channel information, it is determined that there is a hardware Trojan horse. This method is not limited by the type of hardware Trojan and the scale of the circuit. It distributes the deduction relationship between multiple IP cores and assists each other in detection, which greatly improves the detection efficiency of hardware Trojan. In addition, the existing detection technology can be transferred to further Improve its detection efficiency, and distributed detection can effec...
