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 ...

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.

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.

HOP: Hardware makes Obfuscation Practical
Proceedings 2017 Network and Distributed System Security Symposium, 2017Program obfuscation is a central primitive in cryptography, and has important real-world applications in protecting software from IP theft. However, well known results from the cryptographic literature have shown that software only virtual black box (VBB) obfuscation of general programs is impossible.

A Perceptron-Inspired Technique for Hardware Obfuscation
2018 19th International Workshop on Microprocessor and SOC Test and Verification (MTV), 2018Outsourcing the manufacture of integrated circuits (IC) boosts efficiency in terms of production timeline and minimizing expenditures. However, it results in security challenges, as there is uncertainty in the reliability of the foundry that is responsible for the IC fabrication.

Hardware Obfuscation Using Strong PUFs
2018 IEEE Computer Society Annual Symposium on VLSI (ISVLSI), 2018IC piracy is a significant security threat, where malicious manufacturers can produce unauthorized extra chips and/or steal the information of a design through reverse engineering attempts. As a countermeasure, hardware obfuscation schemes usually withhold a part of the design (which thereafter constitutes the "key") by replacing it with configurable ...

Hardware Obfuscation Using Different Obfuscation Cell Structures for PLDs
2017In recent years, hardware obfuscation is one of the prominent anti-tamper solutions that are highly used against various hardware security threats such as piracy, cloning, reverse engineering, chip overbuilding, and hardware Trojans. Logic obfuscation is implemented either in the design description (for soft/firm/hard codes) or structure (for the chip)

Hardware-Software Co-Design Based Obfuscation of Hardware Accelerators
2019 IEEE Computer Society Annual Symposium on VLSI (ISVLSI), 2019Existing logic obfuscation approaches aim to protect hardware design IPs from SAT attack by increasing query count and output corruptibility of a locked netlist. In this paper, we demonstrate the ineffectiveness of such techniques to obfuscate hardware accelerator platforms.
