On the Construction of Composite Finite Fields for Hardware Obfuscation
IEEE Transactions on Computers, 2019Hardware obfuscation is a technique that modifies the circuit to hide the functionality. Obfuscations through algorithmic modifications add protection in addition to circuit-level techniques, and their effects on the data paths can be analyzed and controlled at the architectural level.

Hardware Obfuscation Techniques on FPGA-Based Systems
2020 IEEE East-West Design & Test Symposium (EWDTS), 2020There is a great variety of hardware Trojan detection and prevention approaches. However, state of art approaches cannot provide a full guarantee that an integrated circuit or complex electronic system is free of hardware Trojan. We introduced a reference monitor obfuscation approach on the base of formal transformations of structural system models ...

A Practical Logic Obfuscation Technique for Hardware Security
IEEE Transactions on Very Large Scale Integration (VLSI) Systems, 2016A number of studies of hardware security aim to thwart piracy, overbuilding, and reverse engineering (RE) by obfuscating and/or camouflaging. However, these techniques incur high overheads, and integrated circuit (IC) camouflaging cannot provide any protection for the gate-level netlist of the third party intellectual property (IP) core or the single ...

VLSI Test and Hardware Security Background for Hardware Obfuscation
2017This chapter discusses the fundamental concepts of design and testing and their role in hardware obfuscation. It outlines the traditional design flow of integrated circuits and assesses the vulnerabilities associated with the verification techniques and testing structures that can expose the design details and help reverse-engineer the functionality. A

Circuit Design Obfuscation for Hardware Security
2018Nowadays, chip design and chip fabrication are normally conducted separately by independent companies. Most integrated circuit (IC) design companies are now adopting a fab-less model: they outsource the chip fabrication to offshore foundries while concentrating their effort and resource on the chip design.
