Hardware Trojan horse detection system based on puf

Abstract

The invention relates to a hardware Trojan horse detection system based on puf. The system adds the puf into a plurality of modules of an integrated chip (IC) in an original IC design file, sends the IC design file with the puf to a factory for production, performs data acquisition on an IC sample produced by the factory according to the IC design file with the puf under a test mode, analyzes the acquired data through a data analysis module and outputs a judgment result; and a user judges whether the original IC design in an original data storage module is modified according to original data judged by a data judgment module and judges whether to put the original data into production. The hardware Trojan horse detection system has the advantages that the shortcomings that the conventional detection method is complicated, high in test cost and long in time period, and the original design or the original IC is needed are overcome; whether hardware Trojan horses are contained can be stably and effectively detected; naturally, the fact that the Trojan horses are very difficult to trigger is not considered; the Trojan horses are detected physically; and therefore, most hardware Trojan horses can be detected.

Description

technical field [0001] The invention relates to the technical field of hardware security, in particular to a puf-based hardware Trojan horse detection system. Background technique [0002] IC products are widely used in various industries. Various IC development kits not only bring convenience to designers, but also bury hidden dangers for designing circuits. The IC industry chain is not completely trustworthy. At any link before production, the original design may be added with malicious functions in the unused chip space, or the original design may be maliciously modified, that is, a hardware Trojan horse may be implanted. Once such a circuit is mass-produced and put into use, it may bring huge losses to the national society. Therefore, how to effectively detect whether there is a hardware Trojan has become an extremely urgent problem. [0003] The existing hardware Trojan detection methods can be roughly divided into four categories: [0004] 1. Physical inspection: t...
