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
