Description

technical field [0001] The invention belongs to the field of trustworthiness of integrated circuits, and in particular relates to a hardware Trojan horse detection method based on local area circuit cross-reference. Background technique [0002] With the continuous advancement of integrated circuit manufacturing technology and computer-aided design technology, integrated circuits have gradually become a powerful driving force to promote the progress of the information society. Strategic, basic and leading industries for social development. Due to the advanced nature and complexity of integrated circuits, the complete supply chain of integrated circuits spreads all over the world, and its design and manufacturing process requires the participation of units from different countries and regions, including some attackers or competitors with ulterior motives. Once these security risks penetrate, they can implant hardware Trojan horses in the design and manufacturing process to a...

Problems solved by technology

However, the design and manufacturing process of integrated circuits are gradually separated, and a large number of third-party IP cores are reused in the design process. In addition, the manufacturing process is often completed by the cooperation of third-party manufacturers. The design and manufacturing process is not completely reliable, so its Design data and layout data are not completely reliable

However, reverse analysis can verify and even obtain the golden model of the integrated circuit, but it is necessary to remove the chip package and grind the metal layer of the chip to reconstruct the original layout of the circuit, and the test cost is too expensive

In addition, even if the golden model of reverse analysis is obtained, there are random factors in the manufacturing process of integrated circuits, that is, there are process deviations between integrated circuits, and this deviation is random, and the differences between integrated circuits are difficult to effectively predict, so The golden model constructed from design data or layout data cannot effectively match the actual data

With the continuous advancement of hardware Trojan design technology, its side channel effects are getting weaker and weaker. Its side channel effects are easily overwhelmed by process deviations. Even with an effective golden model, it is difficult to identify small-area hardware Trojans
