The introduction of public key cryptography (PKC) was a critical advance in IT security. In contrast to symmetric key cryptography, it enables confidential communication between entities in open networks, in particular the Internet, without prior contact. Beyond this PKC also enables protection techniques that have no analogue in traditional cryptography, most importantly digital signatures which for example support Internet security by authenticating software downloads and updates. Although PKC does not require the confidential exchange of secret keys, proper management of the private and public keys used in PKC is still of vital importance: the private keys must remain private, and the public keys must be verifiably authentic. So understanding so-called public key infrastructures (PKIs) that manage key pairs is at least as important as studying the ingenious mathematical ideas underlying PKC.

In this book the authors explain the most important concepts underlying PKIs and discuss relevant standards, implementations, and applications. The book is structured into chapters on the motivation for PKI, certificates, trust models, private keys, revocation, validity models, certification service providers, certificate policies, certification paths, and practical aspects of PKI.

This is a suitable textbook for advanced undergraduate and graduate courses in computer science, mathematics, engineering, and related disciplines, complementing introductory courses on cryptography. The authors assume only basic computer science prerequisites, and they include exercises in all chapters and solutions in an appendix. They also include detailed pointers to relevant standards and implementation guidelines, so the book is also appropriate for self-study and reference by industrial and academic researchers and practitioners.

The claim that heritage practice in Asia is Eurocentric may be well-founded, but the view that local people in Asia need to be educated by heritage practitioners and governments to properly conserve their heritage distracts from the responsibility of educating oneself about the local-popular beliefs and practices which constitute the bedrock of most people's engagement with the material past. Written by an archaeologist who has long had one foot in the field of heritage practice and another in the academic camp of archaeology and heritage studies, Counterheritage is at once a forthright critique of current heritage practice in the Asian arena and a contribution to this project of self-education. Popular religion in Asia - including popular Buddhism and Islam, folk Catholicism, and Chinese deity cults - has a constituency that accounts for a majority of Asia's population, making its exclusion from heritage processes an issue of social justice, but more pragmatically it explains why many heritage conservation programs fail to gain local traction. This book describes how the tenets of popular religion affect building and renovation practices and describes how modernist attempts to suppress popular religion in Asia in the early and mid-twentieth century impacted religious 'heritage.' Author Denis Byrne argues that the campaign by archaeologists and heritage professionals against the private collecting and 'looting' of antiquities in Asia largely ignores the regimes of value which heritage discourse has helped erect and into which collectors and local diggers play. Focussing on the Philippines, Thailand, and Taiwan but also referencing China and other parts of Southeast Asia, richly detailed portraits are provided of the way people live with 'old things' and are affected by them. Narratives of the author's fieldwork are woven into arguments built upon an extensive and penetrating reading of the historical and anthropological literature. The critical stance embodied in the title 'counterheritage' is balanced by the optimism of the book's vision of a different practice of heritage, advocating a view of heritage objects as vibrant, agentic things enfolded in social practice rather than as inert and passive surfaces subject to conservation.

This book shows, for the first time, the indispensable role of the Burford Masons, a group of master masons from the historic quarries around Burford, Oxfordshire, in creating some of the foremost buildings of the 17th and early 18th centuries. The Burford Masons were involved in the construction of such outstanding buildings as St Paul's Cathedral, City churches, and Blenheim Palace, among many others. Whilst credit for many of these buildings generally rests with named architects, Sir Christopher Wren in particular, this book shows how reliant these designers were on their master craftsmen, sometimes involving them in the design process as their ideas evolved. The book further shows how the Burford Masons responded to the challenge of late payments, often of many years, becoming financiers in the process. It reveals how, as risk-taking businessmen, they effectively underpinned both public and private development financially, and how extraordinary success transformed their lives. The reader will learn about the vital part played in the early modern period by master craftsmen of the calibre of the Burford Masons, despite the emergence of the architect as lead designer, whose fame has hitherto overshadowed them. As a result, this book will be a compelling read for anyone interested in architectural, construction or social history.

Illustrated with over 100 color images, the case studies include detailed plans and photographs to show how these projects came about, the strategies used by each team to approach the design and construction process, and the obstacles they overcame to realize a successful outcome. The lessons and insights presented will be a valuable resource, whether you're an architect, architecture student, Habitat affiliate leader, or an affordable housing advocate.

The use of modern composite materials in construction offers the structural engineer and designer exciting opportunities for all types of buildings and structures. By far the most commonly used and longest established composite material is the combined use of steel and concrete in the form known in most parts of the world as 'composite construction'. Composite Construction takes a comprehensive look at recent developments in this fast growing area. With each chapter written by an acknowledged expert in the field, this book aims to link physical behaviour, engineering approximation, appropriately applied theoretical concepts and design approaches. Composite Construction is not simply a code commentary, nor does it deal with topics purely in terms of developing theory from first principles. Rather, the emphasis is strongly placed on providing both the practising engineer and the student with an understanding of physical behaviour, and the intelligent application of this knowledge in practice
