Hardware Trojan horse detection system based on puf

TLDR: In this paper, the authors proposed a hardware Trojan horse detection system based on puf, which adds puf into a plurality of modules of an integrated chip (IC) in an original IC design file, sends the IC design files with puf to a factory for production, performs data acquisition on an IC sample produced by the factory according to the IC file with the puf under a test mode, analyzes the acquired data through a data analysis module and outputs a judgment result.

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.
