  • 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.

  • Wireless Medical Sensor Networks for IoT-based eHealth
  • Internet of Things (IoT) enabled technology is evolving healthcare from conventional hubbased systems to more personalized eHealth systems, enabling faster and safer preventive care, lower overall cost, improved patient-centric practice and enhanced sustainability. Efficient IoT-enabled eHealth systems can be realized by providing highly customized access to rich medical information and efficient clinical decisions to each individual with unobtrusive monitoring. Wireless medical sensor networks (WMSNs) are at the heart of this concept, and their development is a key issue if such a concept is to achieve its potential. This book addresses the major challenges in realizing WMSNs in forthcoming IoT-based eHealth systems. Challenges vary from cost and energy efficiency to security and service quality, and to tackle such challenges WMSNs must meet certain expectations and requirements such as size constraints, manufacturing costs and resistance to environmental factors existing at deployment locations. Reflecting this the book focuses on both design and implementation aspects Topics covered include the impact of medical sensor networks in smart-cities; an evaluation of mobile patient monitoring technologies; overview of wireless sensor devices in medical applications; cyber security issues in WMSNs and eHealth; smart hospital rooms and automated systems; medical sensor capabilities in smart cloud networks; swarm intelligence based medical diagnosis systems; and smart systems and device for the blind.

  • Advanced Dielectric Materials for Electrostatic Capacitors
  • Capacitors are passive electrical components that store energy in an electric field. Applications include electric power conditioning, signal processing, motor starting, and energy storage. The maximum charge a capacitor can hold largely depends on the dielectric material inside. That material is the enabler for the performance. Ongoing development in fields such as high-power electronics, renewable energy, hybrid electric vehicles and electric aircraft, is posing an urgent need for more advanced electrostatic capacitor technology. This book for researchers in industry and academia provides an overview of key dielectric materials for capacitor technology. It covers preparation and characterization of state-of-the art dielectric materials including ceramics, polymers and polymer nanocomposites, for the most popular applications including energy storage, microwave communication and multi-layer ceramic capacitors. The book begins with an introduction to electrostatic capacitor technology, then goes on to cover the following topics: techniques for capacitor dielectrics characterization; dielectric polymers and dielectric metamaterials for high energy capacitors; polymer/nanofiller composites; high-temperature polymer-based dielectrics for electrostatic energy storage; design and simulations of capacitor dielectrics by phase-field computations; rational design on polymer dielectrics; inorganic dielectrics for high-energy-density capacitors; ceramic dielectrics for microwave communication; ceramic dielectrics for MLCCs; and finally two chapters on future prospects for polymers and ceramics.

  • 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.
