The fields of cryptography and computational number theory have recently witnessed a rapid development, which was the subject of the CCNT workshop in Singapore in November 1999. Its aim was to stimulate further research in information and computer security as well as the design and implementation of number theoretic cryptosystems and other related areas. Another achievement of the meeting was the collaboration of mathematicians, computer scientists, practical cryptographers and engineers in academia, industry and government. The present volume comprises a selection of refereed papers originating from this event, presenting either a survey of some area or original and new results. They concern many different aspects of the field such as theory, techniques, applications and practical experience. It provides a state-of-the-art report on some number theoretical issues of significance to cryptography.

This book focuses on development of blockchain-based new-generation financial infrastructures, in which a systematic, complete theoretical framework is proposed to explore blockchain-based securities trading platform, central securities depository (CSD), securities settlement system (SSS), central counterparty (CCP), payment system (PS) and trade repository (TR). The blockchain-based new FMI has attracted much attention in the securities industry. At present, the cross-border depository receipt (DR) business faces a dilemma between efficiency and security. In this book, the author proposes a blockchain-based new DR solution, manifesting the potential for using blockchain technology in the FMI field. In addition, using Hashed Timelock Contract (HTLC) as the underlying technology in the DR scenario, specific process and operations are proposed for delivery versus payment (DvP), delivery versus delivery (DvD) or payment versus payment (PvP) and other exchange-of-value methods. This book further studies how to carry out opening positions, end-of-day settlement of margin, forced liquidation and settlement at maturity, for exchange-traded derivatives, such as futures and options, under the blockchain-based technological framework. Blockchain technology not only naturally fits into the decentralized or non-centralized characteristic of the OTC market but also can effectively address the pain points and difficulties of the OTC market. This book provides an in-depth analysis of existing specific issues in China's bond market, regional equity markets and asset management market, among other OTC markets, and proposes relevant blockchain-based solutions. Blockchain technology does not change the public policy objectives for FMI. The blockchain-based new FMIs are still subject to compliance, safety and efficiency requirements. This book provides a comprehensive assessment of the applicability of the Principles for Financial Market Infrastructures (PFMI) to them, in particular, analyzes their legal basis, off-chain governance and system security.

This book is devoted to efficient pairing computations and implementations, useful tools for cryptographers working on topics like identity-based cryptography and the simplification of existing protocols like signature schemes. As well as exploring the basic mathematical background of finite fields and elliptic curves, Guide to Pairing-Based Cryptography offers an overview of the most recent developments in optimizations for pairing implementation. Each chapter includes a presentation of the problem it discusses, the mathematical formulation, a discussion of implementation issues, solutions accompanied by code or pseudocode, several numerical results, and references to further reading and notes. Intended as a self-contained handbook, this book is an invaluable resource for computer scientists, applied mathematicians and security professionals interested in cryptography.

In this introductory textbook the author explains the key topics in cryptography. He takes a modern approach, where defining what is meant by "secure" is as important as creating something that achieves that goal, and security definitions are central to the discussion throughout. The author balances a largely non-rigorous style - many proofs are sketched only - with appropriate formality and depth. For example, he uses the terminology of groups and finite fields so that the reader can understand both the latest academic research and "real-world" documents such as application programming interface descriptions and cryptographic standards. The text employs colour to distinguish between public and private information, and all chapters include summaries and suggestions for further reading. This is a suitable textbook for advanced undergraduate and graduate students in computer science, mathematics and engineering, and for self-study by professionals in information security. While the appendix summarizes most of the basic algebra and notation required, it is assumed that the reader has a basic knowledge of discrete mathematics, probability, and elementary calculus.

Archiving has become an increasingly complex process. The challenge is no longer how to store the data but how to store it intelligently, in order to exploit it over time, while maintaining its integrity and authenticity. Digital technologies bring about major transformations, not only in terms of the types of documents that are transferred to and stored in archives, in the behaviors and practices of the humanities and social sciences (digital humanities), but also in terms of the volume of data and the technological capacity for managing and preserving archives (Big Data). Archives in The Digital Age focuses on the impact of these various digital transformations on archives, and examines how the right to memory and the information of future generations is confronted with the right to be forgotten; a digital prerogative that guarantees individuals their private lives and freedoms.

This book covers the relationship of recent technologies (such as Blockchain, IoT, and 5G) with the cloud computing as well as fog computing, and mobile edge computing. The relationship will not be limited to only architecture proposal, trends, and technical advancements. However, the book also explores the possibility of predictive analytics in cloud computing with respect to Blockchain, IoT, and 5G. The recent advancements in the internet-supported distributed computing i.e. cloud computing, has made it possible to process the bulk amount of data in a parallel and distributed. This has made it a lucrative technology to process the data generated from technologies such as Blockchain, IoT, and 5G. However, there are several issues a Cloud Service Provider (CSP) encounters, such as Blockchain security in cloud, IoT elasticity and scalability management in cloud, Service Level Agreement (SLA) compliances for 5G, Resource management, Load balancing, and Fault-tolerance. This edited book will discuss the aforementioned issues in connection with Blockchain, IoT, and 5G. Moreover, the book discusses how the cloud computing is not sufficient and one needs to use fog computing, and edge computing to efficiently process the data generated from IoT, and 5G. Moreover, the book shows how smart city, smart healthcare system, and smart communities are few of the most relevant IoT applications where fog computing plays a significant role. The book discusses the limitation of fog computing and the need for the edge computing to further reduce the network latency to process streaming data from IoT devices. The book also explores power of predictive analytics of Blockchain, IoT, and 5G data in cloud computing with its sister technologies. Since, the amount of resources increases day-by day, artificial intelligence (AI) tools are becoming more popular due to their capability which can be used in solving wide variety of issues, such as minimize the energy consumption of physical servers, optimize the service cost, improve the quality of experience, increase the service availability, efficiently handle the huge data flow, manages the large number of IoT devices, etc.

Cryptography has been employed in war and diplomacy from the time of Julius Caesar. In our Internet age, cryptography's most widespread application may be for commerce, from protecting the security of electronic transfers to guarding communication from industrial espionage. This accessible introduction for undergraduates explains the cryptographic protocols for achieving privacy of communication and the use of digital signatures for certifying the validity, integrity, and origin of a message, document, or program. Rather than offering a how-to on configuring web browsers and e-mail programs, the author provides a guide to the principles and elementary mathematics underlying modern cryptography, giving readers a look under the hood for security techniques and the reasons they are thought to be secure.

Enterprise Level Security 2: Advanced Topics in an Uncertain World follows on from the authors' first book on Enterprise Level Security (ELS), which covered the basic concepts of ELS and the discoveries made during the first eight years of its development. This book follows on from this to give a discussion of advanced topics and solutions, derived from 16 years of research, pilots, and operational trials in putting an enterprise system together. The chapters cover specific advanced topics derived from painful mistakes and numerous revisions of processes. This book covers many of the topics omitted from the first book including multi-factor authentication, cloud key management, enterprise change management, entity veracity, homomorphic computing, device management, mobile ad hoc, big data, mediation, and several other topics. The ELS model of enterprise security is endorsed by the Secretary of the Air Force for Air Force computing systems and is a candidate for DoD systems under the Joint Information Environment Program. The book is intended for enterprise IT architecture developers, application developers, and IT security professionals. This is a unique approach to end-to-end security and fills a niche in the market.

In 1775, Paul Revere, the folk hero of the American Revolution, galloped wildly on horseback through small towns to warn American colonists that the British were coming. In today's Internet age, how do we warn vast numbers of computers about impending cyber attacks?

Rapid and widespread dissemination of security updates throughout the Internet would be invaluable for many purposes, including sending early-warning signals, distributing new virus signatures, updating certificate revocation lists, dispatching event information for intrusion detection systems, etc. However, notifying a large number of machines securely, quickly, and with high assurance is very challenging. Such a system must compete with the propagation of threats, handle complexities in large-scale environments, address interruption attacks toward dissemination, and also secure itself.

Disseminating Security Updates at Internet Scale describes a new system, "Revere," that addresses these problems. "Revere" builds large-scale, self-organizing and resilient overlay networks on top of the Internet to push security updates from dissemination centers to individual nodes. "Revere" also sets up repository servers for individual nodes to pull missed security updates. This book further discusses how to protect this push-and-pull dissemination procedure and how to secure "Revere" overlay networks, considering possible attacks and countermeasures. Disseminating Security Updates at Internet Scale presents experimental measurements of a prototype implementation of "Revere" gathered using a large-scale oriented approach. These measurements suggest that "Revere" can deliver security updates at the required scale, speed and resiliency for a reasonable cost.

Disseminating Security Updates at Internet Scale is designed to meet the needs of researchers and practitioners in industry and graduate students in computer science. This book will also be helpful to those trying to design peer systems at large scale when security is a concern, since many of the issues faced by these designs are also faced by "Revere." The "Revere" solutions may not always be appropriate for other peer systems with very different goals, but the analysis of the problems and possible solutions discussed here will be helpful in designing a customized approach for such systems.

IT Governance is finally getting the Board's and top management's attention. The value that IT needs to return and the associated risks that need to be managed, have become so important in many industries that enterprise survival depends on it. Information integrity is a significant part of the IT Governance challenge. Among other things, this conference will explore how Information Integrity contributes to the overall control and governance frameworks that enterprises need to put in place for IT to deliver business value and for corporate officers to be comfortable about the IT risks the enterprise faces. The goals for this international working conference are to find answers to the following questions: * what precisely do business managers need in order to have confidence in the integrity of their information systems and their data; * what is the status quo of research and development in this area; * where are the gaps between business needs on the one hand and research I development on the other; what needs to be done to bridge these gaps. The contributions have been divided in the following sections: * Refereed papers. These are papers that have been selected through a blind refereeing process by an international programme committee. * Invited papers. Well known experts present practice and research papers upon invitation by the programme committee. * Tutorial. Two papers describe the background, status quo and future development of CobiT as well as a case of an implementation of Co biT.
