Reusing Logic Masking to Facilitate Hardware Trojan Detection

Abstract

Hardware Trojan (HT) and Integrated Circuit (IC)/ Intellectual Property (IP) piracy are important threats which may happen in untrusted fabrication foundries. Modifying structurally the ICs/IPs design to counter the HT threats has been proposed, and it is known as Design-For-Hardware-Trust (DFHT). DFHT methods are used in order to facilitate HT detection methods. In addition, logic masking methods modify the IPs/ICs design to harden them against the IP/IC piracy. These methods modify a circuit such that it does not work correctly without applying the correct key. In this paper, we propose DFHT methods leveraging logic masking approach.
