Résumé
Outsourcing the fabrication process to low-cost locations has become a major trend in the Integrated Circuits (ICs) industry in the last decade. This trend raises the question about untrusted foundries in which an adversary can tamper with the circuit by inserting a malicious behavior in the ICs, referred to as Hardware Trojans (HTs). The serious impact of HTs in security applications and global economy brings extreme importance to detection as well as prevention techniques. In this paper, we introduce the idea of hardware modified dual modular redundancy (MODMOR): a prevention technique that aims at making the insertion of a stealthy HT more difficult, and at detecting it at run-time.
