Electronic commerce is here to stay. No matter how big the dot-com crisis was or how far the e-entrepreneurs' shares fell in the market, the fact remains that there is still confidence in electronic trading. At least it would appear that investors are confident in e-companies again. However, not only trust of venture capitalists is of importance -- consumers also have to have faith in on-line business. After all, without consumers there is no e-business. Interacting lawyers, technicians and economists are needed to create a trustworthy electronic commerce environment. To achieve this environment, thorough and inter-disciplinary research is required and that is exactly what this book is about. Researchers of the project Enabling Electronic Commerce from the Dutch universities of Tilburg and Eindhoven have chosen a number of e-topics to elaborate on trust from their point of view. This volume makes clear that the various disciplines can and will play a role in developing conditions for trust and thus contribute to a successful electronic market.
A mathematically oriented overview of the field of cryptology. The book discusses conventional cryptosystems from Caesar to DES, with emphasis on the theory of shift register sequences.--
The protection of sensitive information against unauthorized access or fraudulent changes has been of prime concern throughout the centuries. Modern communication techniques, using computers connected through networks, make all data even more vulnerable for these threats. Also, new issues have come up that were not relevant before, e. g. how to add a (digital) signature to an electronic document in such a way that the signer can not deny later on that the document was signed by him/her. Cryptology addresses the above issues. It is at the foundation of all information security. The techniques employed to this end have become increasingly mathematical of nature. This book serves as an introduction to modern cryptographic methods. After a brief survey of classical cryptosystems, it concentrates on three main areas. First of all, stream ciphers and block ciphers are discussed. These systems have extremely fast implementations, but sender and receiver have to share a secret key. Public key cryptosystems (the second main area) make it possible to protect data without a prearranged key. Their security is based on intractable mathematical problems, like the factorization of large numbers. The remaining chapters cover a variety of topics, such as zero-knowledge proofs, secret sharing schemes and authentication codes. Two appendices explain all mathematical prerequisites in great detail. One is on elementary number theory (Euclid's Algorithm, the Chinese Remainder Theorem, quadratic residues, inversion formulas, and continued fractions). The other appendix gives a thorough introduction to finite fields and their algebraic structure.

This comprehensive encyclopedia provides easy access to information on all aspects of cryptography and security. With an A–Z format of over 460 entries, 100+ international experts provide an accessible reference for those seeking entry into any aspect of the broad fields of cryptography and information security. Most entries in this preeminent work include useful literature references, providing more than 2500 references in total. Topics for the encyclopedia were selected by a distinguished advisory board consisting of 18 of the world’s leading scholars and practitioners. Main subject areas include: Authentication and identification.- Block ciphers and stream ciphers.- Computational issues.- Copy protection.- Cryptanalysis and security.- Cryptographic protocols.- Electronic payment and digital certificates.- Elliptic curve cryptography.- Factorization algorithms and primality tests.- Hash functions and MACs.- Historical systems.- Identity-based cryptography.- Implementation aspects for smart cards and standards.- Key management.- Multiparty computations like voting schemes.- Public key cryptography.- Quantum cryptography.- Secret sharing schemes.- Sequences.- Web security. The style of the entries in the Encyclopedia of Cryptography and Security is expository and tutorial rather than detailed and technical, making the book a practical resource for information security experts as well as professionals in other fields who need to access this vital information but who may not have time to work their way through an entire text on their topic of interest. The underlying concepts in information security can be difficult to understand and may even be counter-intuitive. The Encyclopedia of Cryptography and Security will become the premier reference work on this complex subject.
This collection of contributions is offered to Jack van Lint on the occasion of his sixtieth birthday and appears simultaneously in the series Topics in Discrete Mathematics and as a special double volume of Discrete Mathematics (Volumes 106/107). It is hoped that the papers selected, all written by experts in their own fields, represent the many interesting areas that together constitute the discipline of Discrete Mathematics. It is in this sphere that van Lint has become the acknowledged master and this expansive volume serves to demonstrate the enormous significance he has had on the development of Discrete Mathematics during the last 30 years.
