  • Frontiers in Hardware Security and Trust; Theory, design and practice
  • Frontiers in Hardware Security and Trust provides a comprehensive review of emerging ecurity threats and privacy protection issues, and the versatile state-of-the-art hardwarebased security countermeasures and applications proposed by the hardware security community. The footprint and power constraints imposed on internet-of-things end-points, smart sensors, mobile and ad hoc network devices make traditional and software based cryptographic solutions that require a general-purpose processor increasingly unfeasible. The fact that security is not the primary functionality of these devices means that only a small portion of their limited processing power and storage is available for security, driving the need for alternative security solutions. Hardware security - including hardware obfuscation, hardware security primitives, side-channel attacks and so on - is therefore becoming an increasingly active research area in both academia and industry. This book discusses the fundamentals of reversible logics, hardware obfuscations, SAT resistant logic obfuscation, and design-for-security. Novel security primitives such as state-of-the-art true random number generators are also explored. Modern micro-architectural attacks enabled with the superscalar microprocessors and its countermeasures are analysed to shed light on how existing architectures can be fortified or made more robust against attack. The introduction of hardware security into cognitive radio networks, 5G networks and machine learning, which are widely considered to be the most promising major contributors to next wave of technological growth, are also discussed. The book serves as an advanced reference for researchers on current hardware security problems, challenges and solutions.

  • Lightning-Induced Effects in Electrical and Telecommunication Systems
  • Power and telecommunications systems are growing increasingly complex. This increases their vulnerability to lightning-related effects. Due to the high requirements for the reliability of power and telecommunications systems and the associated sensitive equipment, protection against lightning is of paramount importance. Lightning-induced effects are to be quantified in order to assess the risks and design adequate protection. This can be done with the traditional approach, which is based on the transmission-line theory and an electromagnetic-field-to-conductor coupling model, as well as with the advanced numerical techniques, such as the finite difference time-domain (FDTD) method. Interest in the FDTD method is steadily growing because of the availability of software and increased computer capabilities. This book provides an introduction to the FDTD method and its applications to studies of lightning-induced effects in power and telecommunication systems. It also contains background information on lightning, lightning models, and lightning electromagnetics. This book is essential reading for electrical engineers and researchers, who are interested in lightning surge protection studies, as well as for senior undergraduate and graduate students specializing in electrical engineering.

  • Cross-Layer Reliability of Computing Systems
  • Reliability has always been a major concern in designing computing systems. However, the increasing complexity of such systems has led to a situation where efforts for assuring reliability have become extremely costly, both for the design of solutions for the mitigation of possible faults, and for the reliability assessment of such techniques. Cross-layer reliability is fast becoming the preferred solution. In a cross-layer resilient system, physical and circuit level techniques can mitigate low-level faults. Hardware redundancy can be used to manage errors at the hardware architecture layer. Eventually, software implemented error detection and correction mechanisms can manage those errors that escaped the lower layers of the stack. This book presents state-of-the-art solutions for increasing the resilience of computing systems, both at single levels of abstraction and multi-layers. The book begins by addressing design techniques to improve the resilience of computing systems, covering the logic layer, the architectural layer and the software layer. The second part of the book focuses on cross-layer resilience, including coverage of physical stress, reliability assessment approaches, fault injection at the ISA level, analytical modelling for cross-later resiliency, and stochastic methods. Cross-Layer Reliability of Computing Systems is a valuable resource for researchers, postgraduate students and professional computer architects focusing on the dependability of computing systems.

  • Transforming the Grid Towards Fully Renewable Energy
  • The need for a deep decarbonization of the energy sector and the associated opportunities are now increasingly recognized, with fossil fuel projects simultaneously becoming more risky business propositions. With large-scale wind and solar generation now being the cheapest options in many parts of the world, a deeply renewable electricity sector is predestined to become the main driver of this transition. Yet, misconceptions abound. In part, this can be traced back to the complexity of the electricity sector and the processes involved in its transformation, located at the intersection between grid design and operation, markets and regulations. This book is intended to provide some clarity in this matter, by taking the reader from the conceptual foundations of a deeply decarbonized electricity sector in part 1 to new strategies for the renewable energy transition in part 3. Insights into essential building blocks are provided in part 2 where the role of transmission, distributed generation, smart grids, demand response, storage, and forecasting are covered in some detail. The synthesis part 3 explores the connections between the mobility and electricity sectors, the design of renewable economies, and possible roadmaps for a world-wide transition to a deeply decarbonized economy. While striving to be technically rigorous, this book is also meant as an entertaining and inspiring read for researchers and advanced students, experts with the electric power industry, and decision makers in politics, industry and finance.
