Tackling Hardware Trojans via Hardware-based Methodologies
Résumé
Hardware Trojans (HTs) represent significant challenges to the security and reliability of modern microprocessorbased systems. This manuscript introduces two complementary approaches to enhance hardware security. First, programmable Hardware Security Modules are proposed to detect Hardware Trojan Horses by monitoring instruction-fetch activities, identifying malicious interferences, and preventing software-exploitable Hardware Trojan Horse activations. Second, a methodology based on side-channel analysis is proposed to verify the integrity of FPGA bitstreams, allowing the identification of tampered configurations through the extraction and classification of both high-and low-level features.
