Embodiment Construction

[0031] Attached below figure 1 , to further describe in detail the specific steps for realizing the present invention.

[0032] Step 1, sectorize the IC netlist.

[0033] Select 1 integrated circuit (Integrated Circuit, IC) netlist without Trojan horse and 2 integrated circuit netlists with Trojan horse, start with each main output end of the integrated circuit netlist, and gate along the main output end The connection between the circuits is reversely searched, and it stops when it reaches the main input terminal corresponding to the main output terminal, and all the gate circuits found and the connection between them are divided into a sector, and the integrated circuit netlist is finally divided The number of sectors is the same as the number of main output terminals of the integrated circuit netlist.

[0034] The path with the longest path delay in each sector is selected as the critical path.

[0035] Combine below figure 2 Further describe the sector division.

Abstract

The invention discloses an integrated circuit hardware Trojan horse detection method based on multi-parameter bypass analysis. The method comprises the following specific steps: (1) carrying out sector division on an integrated circuit netlist; (2) generating a multi-parameter bypass feature vector; (3) obtaining a Bayesian classifier; (4) detecting the integrated circuit to be detected; (5) judging the prediction label. Through sector division and generation of the multi-parameter bypass feature vector, the accuracy of integrated circuit hardware Trojan horse detection is improved, and Trojanhorse positioning is realized.
