Focusing on both private- and public-key cryptographic algorithms, this book describes algorithmic methods with cryptographically relevant examples. After introducing modern cryptography and elementary number theory and algebra, it covers linear algebra, sieving, brute force, algorithms based on the birthday paradox, Hadamard-Fourier-Walsh transforms, lattice reduction, and Grobner bases. The author also presents advanced applications, such as LFSR-based stream ciphers, lattice methods for cryptanalysis, elliptic curves, and index calculus methods. He includes some hints and solutions to...

There is a significant need for a comprehensive book addressing the operational and day-to-day security management requirements. IM, used in enterprise networks can easily be reconfigured and allow for potentially nonstop exposure; they require the level of security be scrutinized carefully. This includes inherent security flaws in various network architectures that result in additional risks to otherwise secure converged networks. A few books cover components of the architecture, design, theory, issues, challenges, and recommended policies for IM security, but none of them address IM...

Transactional Information Systems is the long-awaited, comprehensive work from leading scientists in the transaction processing field. Weikum and Vossen begin with a broad look at the role of transactional technology in today's economic and scientific endeavors, then delve into critical issues faced by all practitioners, presenting today's most effective techniques for controlling concurrent access by multiple clients, recovering from system failures, and coordinating distributed transactions. The authors emphasize formal models that are easily applied across fields, that promise to...

Protect your digital resources This book addresses critical issues of preservation, giving you everything you need to effectively protect your resources-from dealing with obsolescence, to responsibilities, methods of preservation, cost, and metadata formats. It also gives examples of numerous national and international institutions that provide frameworks for digital libraries and archives. A long-overdue text for anyone involved in the preservation of digital information, this book is critical in understanding today's methods and practices, intellectual discourse, and preservation...

Significantly updated and expanded, this second edition offers a far more comprehensive and sophisticated treatment of the subject area than can be found in other sources. It revisits the subject of cataloging and analyzes it in the context of today's digital environment, providing a fascinating examination of the components that are crucial for successful and effective subject retrieval in online public access catalogs. From language issues to problems of indexing and classification, this book guides you through the theoretical and practical frameworks of information storage and retrieval...

Cryptography, the science of secret writing, is the biggest, baddest security tool in the application programmer's arsenal. Cryptography provides three services that are crucial in secure programming. These include a cryptographic cipher that protects the secrecy of your data; cryptographic certificates, which prove identity (authentication); and digital signatures, which ensure your data has not been damaged or tampered with.This book covers cryptographic programming in Java. Java 1.1 and Java 1.2 provide extensive support for cryptography with an elegant architecture, the Java...
