This book demonstrates the breadth and depth of IP protection through logic locking, considering both attacker/adversary and defender/designer perspectives. The authors draw a semi-chronological picture of the evolution of logic locking during the last decade, gathering and describing all the DO’s and DON’Ts in this approach. They describe simple-to-follow scenarios and guide readers to navigate/identify threat models and design/evaluation flow for further studies. Readers will gain a comprehensive understanding of all fundamentals of logic locking.

This is the first book dedicated to hands-on hardware security training. It includes a number of modules to demonstrate attacks on hardware devices and to assess the efficacy of the countermeasure techniques. This book aims to provide a holistic hands-on training to upper-level undergraduate engineering students, graduate students, security researchers, practitioners, and industry professionals, including design engineers, security engineers, system architects, and chief security officers. All the hands-on experiments presented in this book can be implemented on readily available Field Programmable Gate Array (FPGA) development boards, making it easy for academic and industry professionals to replicate the modules at low cost. This book enables readers to gain experiences on side-channel attacks, fault-injection attacks, optical probing attack, PUF, TRNGs, odometer, hardware Trojan insertion and detection, logic locking insertion and assessment, and more.

This book introduces readers to various threats faced during design and fabrication by today’s integrated circuits (ICs) and systems. The authors discuss key issues, including illegal manufacturing of ICs or “IC Overproduction,” insertion of malicious circuits, referred as “Hardware Trojans”, which cause in-field chip/system malfunction, and reverse engineering and piracy of hardware intellectual property (IP). The authors provide a timely discussion of these threats, along with techniques for IC protection based on hardware obfuscation, which makes reverse-engineering an IC design infeasible for adversaries and untrusted parties with any reasonable amount of resources. This exhaustive study includes a review of the hardware obfuscation methods developed at each level of abstraction (RTL, gate, and layout) for conventional IC manufacturing, new forms of obfuscation for emerging integration strategies (split manufacturing, 2.5D ICs, and 3D ICs), and on-chip infrastructure needed for secure exchange of obfuscation keys- arguably the most critical element of hardware obfuscation.
