On Obfuscating Programs with Tamper-proof Hardware
2011In recent years, theoretical cryptography community has focused on a fascinating research line of obfuscating programs (circuits). Loosely speaking, obfuscating a program P is to construct a new program which can preserve P's functionality, but its code is fully "unintelligent".

On the optimization of Software Obfuscation against Hardware Trojans in Microprocessors
2022 25th International Symposium on Design and Diagnostics of Electronic Circuits and Systems (DDECS), 2022The quest of low production cost and short time-tomarket, as well as the complexity of modern integrated circuits pushed towards a globalization of the supply chain of silicon devices. Such production paradigm raised a number of security threats among which Hardware Trojan Horses (HTHs), that became a serious issue not only for academy but also for ...

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 ...

An Orthogonal Algorithm for Key Management in Hardware Obfuscation
2019 Asian Hardware Oriented Security and Trust Symposium (AsianHOST), 2019The globalization of supply chain makes semiconductor chips susceptible to various security threats. Design obfuscation techniques have been widely investigated to thwart intellectual property (IP) piracy attacks. Key distribution among IP providers, system integration team, and end users remains as a challenging problem.

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.

Hardware obfuscation for IP protection
2020The horizontal business model adopted by the semiconductor industry has resulted in a manufacturing process that has integrated various foreign entities focusing on individual production steps. However, serious trust issues have emerged with the internationalization of the semiconductor supply chain, and the trust concerns grow further with the ...

Hardware-assisted code obfuscation
2014Software obfuscation is a longstanding and open research challenge in computer security. While theoretical results indicate that provably secure obfuscation in general is impossible to achieve, many application areas (e.g. malware, commercial software, etc.) show that software obfuscation is indeed employed in practice.

2018 IEEE 3rd International Verification and Security Workshop (IVSW), 2018
Due to the complexity of digital circuits manufacturing, nowadays most semi-conductor companies outsource part of the fabrication process, reducing both the production costs and the time- to- market. However, as untrusted parties are involved in the production-chain, new security risks arise, and the threat of Hardware Trojans is a serious concern for ...

A hardware obfuscation technique for manufacturing a secure 3D IC
2018 IEEE 61st International Midwest Symposium on Circuits and Systems (MWSCAS), 20183D Integrated Circuit (3D-IC) is an emerging technology that can address many challenging problems threatening the security of the chip by split manufacturing [1]. One of the disadvantages of split manufacturing is the uncertainty in the reliability of the last foundry that is responsible for the complete bonding of tiers.
