A system-level chip security design method based on untrusted ip core

Abstract

The present invention relates to a system-level chip security design method based on an untrustworthy IP core. First, high-order synthesis technology is used to complete the security design of RTL; then the RTL file of the chip is converted into a gate-level netlist through a series of logic synthesis; and then Analyze the logical structure of the gate-level netlist and extract standard netlist features; divide the collected standard netlist feature samples of gate-level circuits into training data sets and test data sets, and use the training data sets to train the gradient boosting algorithm, and get A hardware Trojan classifier based on gradient boosting; finally, through the cross-validation method, the test data set is input into the trained gradient boosting Trojan classifier, and the hardware Trojan horse prediction result based on this model is obtained. The present invention designs a SoC security design framework with strong adaptability, high reusability, wide expansibility, fast and intelligent from the source of IP supply chain.

Description

technical field [0001] The invention relates to the field of integrated circuit information security, in particular to a system-level chip security design method based on an untrustworthy IP core. Background technique [0002] With the development of wireless communication, sensor technology, embedded system and microelectronic technology, the issue of integrated circuit information security is facing unprecedented challenges. [0003] At present, under the trend of globalization of the semiconductor supply chain, the integrated circuit industry needs to use third-party Intellectual Property (3PIP) IP cores designed / manufactured in different countries or regions to complete the System-on-Chip (System-on-Chip, 3PIP) IP core. : SoC) production. The traditional strategy of treating the underlying hardware as a safe and reliable security protection has failed, and untrusted suppliers can directly or indirectly implant malicious circuits into various stages of IC production. Do...

But the disadvantage is that the mixed use of multiple IP cores will increase additional technical overhead, and the design of Trojan horse isolation and detection also increases production costs, and this method fails to consider information leakage Trojan horse detection

[0007] Due to the wide application of integrated circuits in agricultural and industrial environments, most of the existing trusted design methods do not support multiple types of hardware Trojan horse protection. The strategy will lead to a longer manufacturing cycle, which cannot meet the current tight IC market demand
