Journal ArticleDOI
HARPOON: An Obfuscation-Based SoC Design Methodology for Hardware Protection
TL;DR: Simulation results for a set of ISCAS-89 benchmark circuits and the advanced-encryption-standard IP core show that high levels of security can be achieved at less than 5% area and power overhead under delay constraint.
Book ChapterDOI
MERO: A Statistical Approach for Hardware Trojan Detection
TL;DR: A test pattern generation technique based on multiple excitation of rare logic conditions at internal nodes that maximizes the probability of inserted Trojans getting triggered and detected by logic testing, while drastically reducing the number of vectors compared to a weighted random pattern based test generation.
Proceedings ArticleDOI
Hardware Trojan: Threats and emerging solutions
TL;DR: The threat posed by hardware Trojans and the methods of deterring them are analyzed, a Trojan taxonomy, models of Trojan operations and a review of the state-of-the-art Trojan prevention and detection techniques are presented.
Journal ArticleDOI
Hardware Trojan Detection by Multiple-Parameter Side-Channel Analysis
Seetharam Narasimhan,Dongdong Du,Rajat Subhra Chakraborty,Somnath Paul,Francis Wolff,Christos A. Papachristou,Kaushik Roy,Swarup Bhunia +7 more
TL;DR: A novel noninvasive, multiple-parameter side-channel analysisbased Trojan detection approach that uses the intrinsic relationship between dynamic current and maximum operating frequency of a circuit to isolate the effect of a Trojan circuit from process noise.
Proceedings ArticleDOI
Security against hardware Trojan through a novel application of design obfuscation
TL;DR: Simulation results for a set of benchmark circuits show that the proposed obfuscation scheme is capable of achieving high levels of security at modest design overhead and makes some inserted Trojans benign by making them activate only in the obfuscated mode.
