Frequently enabled by digitalization, great transformations are taking place in socio-technical systems such as energy, telecommunications, and mobility. These transformations indicate widespread shifts in societal infrastructure systems, rearranging relations between governments, industries, NGOs, and consumers. In this context, the question of trust in systems – as introduced by sociologists Luhmann, Coleman and Giddens – acquires new urgency, as yet uncommented upon in trust research, or socio-technical systems debates. Focusing on the energy sector, Patrick Sumpf analyzes the meanings of system and trust to develop a framework for both theoretical and empirical research, which is synthesized into an “Architecture of Trust” in systems.

Learn to analyze and measure risk by exploring the nature of trust and its application to cybersecurity Trust in Computer Systems and the Cloud delivers an insightful and practical new take on what it means to trust in the context of computer and network security and the impact on the emerging field of Confidential Computing. Author Mike Bursell’s experience, ranging from Chief Security Architect at Red Hat to CEO at a Confidential Computing start-up grounds the reader in fundamental concepts of trust and related ideas before discussing the more sophisticated applications of these concepts to various areas in computing. The book demonstrates in the importance of understanding and quantifying risk and draws on the social and computer sciences to explain hardware and software security, complex systems, and open source communities. It takes a detailed look at the impact of Confidential Computing on security, trust and risk and also describes the emerging concept of trust domains, which provide an alternative to standard layered security. Foundational definitions of trust from sociology and other social sciences, how they evolved, and what modern concepts of trust mean to computer professionals A comprehensive examination of the importance of systems, from open-source communities to HSMs, TPMs, and Confidential Computing with TEEs. A thorough exploration of trust domains, including explorations of communities of practice, the centralization of control and policies, and monitoring Perfect for security architects at the CISSP level or higher, Trust in Computer Systems and the Cloud is also an indispensable addition to the libraries of system architects, security system engineers, and master’s students in software architecture and security.

This book constitutes the refereed proceedings of the 4th International Conference on Trust and Trustworthy Computing, TRUST 2011, held in Pittsburgh, PA, USA in June 2011. The 23 revised full papers presented were carefully reviewed and selected for inclusion in the book. The papers are organized in technical sessions on cloud and virtualization, physically unclonable functions, mobile device security, socio-economic aspects of trust, hardware trust, access control, privacy, trust aspects of routing, and cryptophysical protocols.

'An excellent collection of texts that can be recommended both to researchers and to others interested in cooperative risk management... Siegrist, Earle, Gutscher and their contributors have produced a well-written and finely edited book that improves the understandings of the relationships between trust, risk and uncertainty in cooperative risk management.'-Journal of Risk Research 'Given the importance of trust as a factor in risk communication studies, this book offers both communication scholars and their students an excellent conceptual resource.'-Science Communication '[A]n excellent introduction into the great variety of trust studies'-Journal of Human and Ecological Risk Assessment 'Everyone knows that trust is important in managing environmental and technological risks, yet there is little agreement on the nature of trust and how to study it. Siegrist, Earle and Gutscher convinced leading American and European scholars to write twelve original essays to try to make sense of the origins and consequences of the uncertainty and scepticism common in the public mind. Although the authors use different methods, conceptual frameworks, models and theories, they all write with fervour (perhaps reflecting the importance of the topic), but maintain the highest standards of scholarship. The chapters complement each other so that the value of this book is greater than the sum of the individual chapters. Indispensable to anyone concerned with trust in cooperative risk management.'-Robert E. O'Connor, National Science Foundation Trust is an important factor in risk management, affecting judgements of risk and benefit, technology acceptance and other forms of cooperation. In this book, the world's leading risk researchers explore all aspects of trust as it relates to risk management and communication. The authors draw on a wide variety of disciplinary approaches and empirical case studies on topics such as mobile phone technology, food accidents and crises, wetland management, smallpox vaccination, management of US forests and the disposal of the Brent Spar oil drilling platform. Insightful analyses are provided for researchers and students of environmental and social science and professionals engaged in risk management and communication in both public and private sectors. Michael Siegrist is Lecturer and Senior Researcher at the University of Zurich and ETH Zurich, Switzerland. Timothy C. Earle is a Research Associate at Western Washington University, Bellingham, US. Heinz Gutscher is Professor of Social Psychology at the University of Zurich, Switzerland.

This book constitutes the refereed proceedings of the Third International Conference on Autonomic and Trusted Computing, ATC 2006, held in Wuhan, China in September 2006. The 57 revised full papers presented together with two keynotes were carefully reviewed and selected from 208 submissions. The papers are organized in topical sections.
