A subtle change that leads to disastrous consequences—hardware Trojans undoubtedly pose one of the greatest security threats to the modern age. How to protect hardware against these malicious modifications? One potential solution hides within logic locking; a prominent hardware obfuscation technique. In this book, we take a step-by-step approach to understanding logic locking, from its fundamental mechanics, over the implementation in software, down to an in-depth analysis of security properties in the age of machine learning. This book can be used as a reference for beginners and experts alike who wish to dive into the world of logic locking, thereby having a holistic view of the entire infrastructure required to design, evaluate, and deploy modern locking policies.

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.

With the popularity of hardware security research, several edited monograms have been published, which aim at summarizing the research in a particular field. Typically, each book chapter is a recompilation of one or more research papers, and the focus is on summarizing the state-of-the-art research. Different from the edited monograms, the chapters in this book are not re-compilations of research papers. The book follows a pedagogical approach. Each chapter has been planned to emphasize the fundamental principles behind the logic locking algorithms and relate concepts to each other using a systematization of knowledge approach. Furthermore, the authors of this book have contributed to this field significantly through numerous fundamental papers.

With the globalization of the semiconductor industry and increased reliance on intellectual property (IP) blocks in integrated circuit (IC) design; malicious modifications, IP theft, and cloning have started to pose a significant economic and security threat. To mitigate this risk, logic locking (LL) techniques have been proposed to obscure the chip functionality and increase the difficulty to insert a trigger-based change via a hardware trojan. This is accomplished through the introduction of localized key gates, which corrupt the IC's function unless the correct key is supplied. The effectiveness of any LL technique, however, depends on the target design, the extent of locking, and where the locking elements are placed. Current attacks on LL focus primarily on Boolean satisfiability problem (SAT) solvers, which require the use of a fully operational chip (oracle) and rely solely on the input and output data through functional testing. To the authors' best knowledge, no current attacks exploit the design's underlying structure, vast amount of repetition, or circuit reuse. In this work, we propose a systematic method, borrowed from the network analysis domain, to analyze and exploit the local and global structure of circuits. The methods presented in this work demonstrates that LL minimally effects the underlying structure, allowing for circuit identification and key bit prediction without the need of an oracle. Moreover, this work also presents a framework in which to capture the security level of LL based on the amount of information leakage through our analysis techniques. Additionally, the framework can be expanded to incorporate other attack methods to create an overall security assessment of any implemented LL. To this end, the analyses and theory introduced in this work demonstrate the need for new comprehensive LL techniques, and proposes the method in which to validate their security.

"As the technology node size for integrated circuit (IC) designs decreases, the cost of building and maintaining an IC foundry rapidly increases. Companies unable to afford local manufacturing have become reliant on outsourcing the physical manufacturing process. This introduces confidentiality, integrity, and authenticity security vulnerabilities into the IC design lifecycle. Even companies that manufacture in-house and use field-programmable gate array (FPGA) chips may require third-party system integrators to assemble the final product. When said product is sent to a third-party foundry or system integrator, the embodied IC/FPGA circuitry is susceptible to IP theft, Trojan insertion, and reverse engineering (RE) attacks. To address this, we realize a novel approach to sequential logic locking, FSMLock, that conceals a finite state machine's (FSM) output and next-state logic through classical encryption. The FSM is abstracted as the configuration data for a lookup table (LUT), encrypted with a chip-specific (individual) internal key, and stored in the newly mandated non-volatile memory (NVM). The configuration data is then decrypted in blocks and loaded into the in-scope random access memory (RAM) when required. Doing so locks the sequential FSM logic and conceals its functionality from third-party foundries and system integrators, system design engineers with access to the post-locked hardware description language (HDL) files, and end-users with production units. FSMLock has applications in reconfigurable hardware, such as FPGAs, even when no third-party access is initially required. In older and low-cost FPGA devices with externally stored bitstream configurations, the absence of trusted bitstream encryption/authentication means that if the bitstream is recovered from the external memory device, an adversary can reconstruct and modify the original design functionality. FSMLock can improve the security of such FPGA chips by storing targeted FSM logic in encrypted NVM. Therefore, a breach of the bitstream contents and the NVM's individual internal key would be required to compromise the security of the targeted sequential circuitry. Further, if a key preprocessor utilizing a physically unclonable function (PUF) is included to discriminate the boundary level (chip) key from the internal key, the confidentiality of the locked circuit is assured, even considering the disclosure of a chip key with its paired encrypted NVM configuration. For the scope of this thesis, we sought to develop an automated software toolset capable of translating pre-partitioned FSMs into encrypted memory configurations. When the configuration is combined with the provided HDL entity responsible for run-time decryption and scope control, a locked HDL model of the FSM, i.e., the FSMLock primitive, is formed."--Abstract.

This book documents some of the most recent advances on the physical layer of the Internet of Things (IoT), including sensors, circuits, and systems. The application area selected for illustrating these advances is that of autonomous, wearable systems for real-time medical diagnosis. The book is unique in that it adopts a holistic view of such systems and includes not only the sensor and processing subsystems, but also the power, communication, and security subsystems. Particular attention is paid to the integration of these IoT subsystems as well as the prototyping platforms needed for achieving such integration. Other unique features include the discussion of energy-harvesting subsystems to achieve full energy autonomy and the consideration of hardware security as a requirement for the integrity of the IoT physical layer. One unifying thread of the various designs considered in this book is that they have all been fabricated and tested in an advanced, low-power CMOS process, namely GLOBALFOUNDRIES 65nm CMOS LPe.
