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.

Hardware Obfuscation Methods for Hardware Trojan Prevention and Detection
2017The globalized semiconductor supply chain make integrated circuits (ICs) potentially suffer from diverse security threats. Among different hardware attacks, Trojan horse insertion has emerged as a major security concern. To mitigate the hardware Trojan insertion happened in the late stage of IC supply chain, researchers recognize that hardware ...

Hardware assisted control flow obfuscation for embedded processors
Proceedings of the 2004 international conference on Compilers, architecture, and synthesis for embedded systems, 2004With more applications being deployed on embedded platforms, software protection becomes increasingly important. This problem is crucial on embedded systems like financial transaction terminals, pay-TV access-control decoders, where adversaries may easily gain full physical accesses to the systems and critical algorithms must be protected from being ...

Hardware Obfuscation: Techniques and Open Challenges
2017While hardware obfuscation has been used in industry for many years, very few scientific papers discuss layout-level obfuscation. The main aim of this paper is to start a discussion about hardware obfuscation in the academic community and point out open research problems. In particular, we introduce a very flexible layout-level obfuscation tool that we

A General and Efficient Obfuscation for Programs with Tamper-Proof Hardware
2011Obfuscating programs is a fascinating area of cryptography. The known general method of obfuscating programs with tamperproof hardware is to first transform a program P to the corresponding ensemble of circuits and then apply the known obfuscation for circuits, e.g. the one by Goyal et al. in TCC'10, to obfuscate some circuit in the ensemble.
