Integer Algorithms in Cryptology and Information Assurance is a collection of the author's own innovative approaches in algorithms and protocols for secret and reliable communication. It concentrates on the "what" and "how" behind implementing the proposed cryptographic algorithms rather than on formal proofs of "why" these algorithms work.The book consists of five parts (in 28 chapters) and describes the author's research results in:This text contains innovative cryptographic algorithms; computationally efficient algorithms for information assurance; new methods to solve the classical problem of integer factorization, which plays a key role in cryptanalysis; and numerous illustrative examples and tables that facilitate the understanding of the proposed algorithms.The fundamental ideas contained within are not based on temporary advances in technology, which might become obsolete in several years. The problems addressed in the book have their own intrinsic computational complexities, and the ideas and methods described in the book will remain important for years to come.

Multi-application smart cards have yet to realise their enormous potential, partly because few people understand the technology, market, and behavioural issues involved. Here, Mike Hendry sets out to fill this knowledge gap with a comprehensive and accessible guide. Following a review of the state-of-the-art in smart card technology, the book describes the business requirements of each smart-card-using sector, and the systems required to support multiple applications. Implementation aspects, including security, are treated in detail and numerous international case studies cover identity, telecoms, banking and transportation applications. Lessons are drawn from these studies to help deliver more successful projects in the future. Invaluable for users and integrators specifying, evaluating and integrating multi-application systems, the book will also be useful to terminal, card and system designers; network, IT and security managers; and software specialists.

Are you serious about network security? Then check out SSH, the Secure Shell, which provides key-based authentication and transparent encryption for your network connections. It's reliable, robust, and reasonably easy to use, and both free and commercial implementations are widely available for most operating systems. While it doesn't solve every privacy and security problem, SSH eliminates several of them very effectively.

Everything you want to know about SSH is in our second edition of "SSH, The Secure Shell: The Definitive Guide," This updated book thoroughly covers the latest SSH-2 protocol for system administrators and end users interested in using this increasingly popular TCP/IP-based solution.

How does it work? Whenever data is sent to the network, SSH automatically encrypts it. When data reaches its intended recipient, SSH decrypts it. The result is "transparent" encryption-users can work normally, unaware that their communications are already encrypted. SSH supports secure file transfer between computers, secure remote logins, and a unique "tunneling" capability that adds encryption to otherwise insecure network applications. With SSH, users can freely navigate the Internet, and system administrators can secure their networks or perform remote administration.

Written for a wide, technical audience, "SSH, The Secure Shell: The Definitive Guide" covers several implementations of SSH for different operating systems and computing environments. Whether you're an individual running Linux machines at home, a corporate network administrator with thousands of users, or a PC/Mac owner who just wants a secure way to telnet or transfer files between machines, ourindispensable guide has you covered. It starts with simple installation and use of SSH, and works its way to in-depth case studies on large, sensitive computer networks.

No matter where or how you're shipping information, "SSH, The Secure Shell: The Definitive Guide" will show you how to do it securely.

How to solve security issues and problems arising in distributed systems.

Security is one of the leading concerns in developing dependable distributed systems of today, since the integration of different components in a distributed manner creates new security problems and issues. Service oriented architectures, the Web, grid computing and virtualization - form the backbone of today's distributed systems. A lens to security issues in distributed systems is best provided via deeper exploration of security concerns and solutions in these technologies.

"Distributed Systems Security" provides a holistic insight into current security issues, processes, and solutions, and maps out future directions in the context of today's distributed systems. This insight is elucidated by modeling of modern day distributed systems using a four-tier logical model -host layer, infrastructure layer, application layer, and service layer (bottom to top). The authors provide an in-depth coverage of security threats and issues across these tiers. Additionally the authors describe the approaches required for efficient security engineering, alongside exploring how existing solutions can be leveraged or enhanced to proactively meet the dynamic needs of security for the next-generation distributed systems. The practical issues thereof are reinforced via practical case studies.

The Cryptographers' Track (CT-RSA) is a research conference within the RSA conference, the largest, regularly staged computer security event. CT-RSA 2004 was the fourth year of the Cryptographers' Track, and it is now an established venue for presenting practical research results related to cryptography and data security. The conference received 77 submissions, and the program committee sel- ted 28 of these for presentation. The program committee worked very hard to evaluate the papers with respect to quality, originality, and relevance to cryp- graphy. Each paper was reviewed by at least three program committee members. Extended abstracts of the revised versions of these papers are in these proc- dings. The program also included two invited lectures by Dan Boneh and Silvio Micali. I am extremely grateful to the program committee members for their en- mous investment of time and e?ort in the di?cult and delicate process of review and selection. Many of them attended the program committee meeting during the Crypto 2003 conference at the University of California, Santa Barbara.

Die Kommunikation ber das Internet ist quasi ffentlich: Dritte k nnen Nachrichten mitlesen, abfangen oder f lschen. Genauso kann ein Sender einer Nachricht behaupten, diese nie gesendet zu haben, und ein Empf nger kann behaupten, eine Nachricht nie erhalten zu haben. Abhilfe schafft die Kryptografie. Sie erm glicht nicht nur die Verschl sselung von Nachrichten, sondern auch digitale Unterschriften, die Authentifizierung und die Anonymisierung von Kommunikationspartnern. Das hier vorliegende Buch ist eine Einf hrung in die Kryptografie f r Studierende - von der symmetrischen ber die asymmetrische Verschl sselung bis hin zu Hash-Funktionen. Umfassend, keinesfalls oberfl chlich, aber ohne Vorwissen verst ndlich.
