Doppelganger Obfuscation — Exploring theDefensive and Offensive Aspects of Hardware Camouflaging

Transactions on Cryptographic Hardware and Embedded Systems, 2020
Hardware obfuscation is widely used in practice to counteract reverse engineering. In recent years, low-level obfuscation via camouflaged gates has been increasingly discussed in the scientific community and industry.

Scalable Hardware Trojan Diagnosis [PDF]

IEEE Transactions on Very Large Scale Integration (VLSI) Systems, 2012
Hardware Trojans (HTs) pose a significant threat to the modern and pending integrated circuit (IC). Due to the diversity of HTs and intrinsic process variation (PV) in IC design, detecting and locating HTs is challenging. Several approaches have been proposed to address the problem, but they are either incapable of detecting various types of HTs or ...

System-level protection and hardware Trojan detection using weighted voting

Journal of Advanced Research, 2014
The problem of hardware Trojans is becoming more serious especially with the widespread of fabless design houses and design reuse. Hardware Trojans can be embedded on chip during manufacturing or in third party intellectual property cores (IPs) during ...

Identification of Hardware Trojans triggering signals

, 2013
International audienceHardware Trojans are malicious alterations to a circuit. These modifications can be inserted either during the design phase or during the fabrication process. Due to the diversity of Hardware Trojans (HTs), detecting and/or locating
