This volume explains the technology behind digital signatures and key infrastructures (PKI). These are the standards that make it absolutely safe to buy, sell, sign documents and exchange sensitive financial data on the Internet.

Explore business and technical implications Understand established regulatory standards Deploy and manage digital signatures Enable business with digital signatures Digital documents are increasingly commonplace in today's business world, and forward-thinking organizations are deploying digital signatures as a crucial part of their part of their strategy. Businesses are discovering a genuine market demand for digital signatures in support of organizational goals. This book is your guide to the new business environment. It outlines the benefits of embracing digital signature techniques and demystifies the relevant technologies. Advance your organization's digital strategy Provide strong non-repudiation Offer "what you see is what you sign" Ensure enhanced security Provide user convenience and mobility

Using case law from multiple jurisdictions, Stephen Mason examines the nature and legal bearing of electronic signatures.

As a beginning graduate student, I recall being frustrated by a general lack of acces sible sources from which I could learn about (theoretical) cryptography. I remember wondering: why aren’t there more books presenting the basics of cryptography at an introductory level? Jumping ahead almost a decade later, as a faculty member my graduate students now ask me: what is the best resource for learning about (various topics in) cryptography? This monograph is intended to serve as an answer to these 1 questions — at least with regard to digital signature schemes. Given the above motivation, this book has been written with a beginninggraduate student in mind: a student who is potentially interested in doing research in the ?eld of cryptography, and who has taken an introductory course on the subject, but is not sure where to turn next. Though intended primarily for that audience, I hope that advanced graduate students and researchers will ?nd the book useful as well. In addition to covering various constructions of digital signature schemes in a uni?ed framework, this text also serves as a compendium of various “folklore” results that are, perhaps, not as well known as they should be. This book could also serve as a textbook for a graduate seminar on advanced cryptography; in such a class, I expect the entire book could be covered at a leisurely pace in one semester with perhaps some time left over for excursions into related topics.

"Web Security, Privacy & Commerce" cuts through the hype and the front page stories. It tells readers what the real risks are and explains how to minimize them. Whether a casual (but concerned) Web surfer or a system administrator responsible for the security of a critical Web server, this book will tells users what they need to know.

Digital certificates, a new form of electronic ID, is a new security technology that establishes a digital identity for a person or a company and guarantees the authenticity of information delivered over the Web or via email. This title explores all of the critical aspects of digital certificates in detail and provides basic information on cryptography. The CD-ROM contains a complete system for controlling access to information on the Internet based on digital certificate technology.

How sonically distinctive digital “signatures”—including reverb, glitches, and autotuning—affect the aesthetics of popular music, analyzed in works by Prince, Lady Gaga, and others. Is digital production killing the soul of music? Is Auto-Tune the nadir of creative expression? Digital technology has changed not only how music is produced, distributed, and consumed but also—equally important but not often considered—how music sounds. In this book, Ragnhild Brøvig and Anne Danielsen examine the impact of digitization on the aesthetics of popular music. They investigate sonically distinctive “digital signatures”—musical moments when the use of digital technology is revealed to the listener. The particular signatures of digital mediation they examine include digital reverb and delay, MIDI and sampling, digital silence, the virtual cut-and-paste tool, digital glitches, microrhythmic manipulation, and autotuning—all of which they analyze in specific works by popular artists. Combining technical and historical knowledge of music production with musical analyses, aesthetic interpretations, and theoretical discussions, Brøvig and Danielsen offer unique insights into how digitization has changed the sound of popular music and the listener's experience of it. For example, they show how digital reverb and delay have allowed experimentation with spatiality by analyzing Kate Bush's “Get Out of My House”; they examine the contrast between digital silence and the low-tech noises of tape hiss or vinyl crackle in Portishead's “Stranger”; and they describe the development of Auto-Tune—at first a tool for pitch correction—into an artistic effect, citing work by various hip-hop artists, Bon Iver, and Lady Gaga.

The EUROCRYPT ’96 conference was sponsored by the International Asso- ation for Cryptologic Research (IACR)l, in cooperation with the University of Saragossa. It took place at the Palacio de Congresos in Saragossa, Spain, during May 12-16, 1996. This was the fifteenth annual EUROCRYPT conference (this name has been used since the third conference held in 1984), each of which has been held in a different city in Europe. For the second time, proceedings were available at the conference. JosC Pastor Franco, the General Chair, was resp- sible for local organization and registration. His contribution to the snccess of the conference is gratefully acknowledged. The Program Committee considered 126 submitted papers and selected 34 for presentation. Each paper was sent to all members of the Program Committee and was assigned to at least three of them for careful evaluation. There were also two invited talks. James L. Massey, this year’s IACR Distinguished Ltcturer, gave a lecture entitled “The difficulty with difficulty”. Massey is the third to receive this honor, the first two being Gustavus Simmons and Adi Shamir. Shafi Goldwasser gave an invited talk entitled “Multi party secure protocols: past and present”. These proceedings contain revised versions of the 34 contributed talks. While the papers were carefully selected, they have not been refereed like submissions to a refereed journal. The authors bear full responsibility for the contents of their papers. Some authors may write final versions of their papers for publication in a refereed journal.

CRYPTO is a conference devoted to all aspects of cryptologic research. It is held each year at the University of California at Santa Barbara. Annual meetings on this topic also take place in Europe and are regularly published in this Lecture Notes series under the name of EUROCRYPT. This volume presents the proceedings of the ninth CRYPTO meeting. The papers are organized into sections with the following themes: Why is cryptography harder than it looks?, pseudo-randomness and sequences, cryptanalysis and implementation, signature and authentication, threshold schemes and key management, key distribution and network security, fast computation, odds and ends, zero-knowledge and oblivious transfer, multiparty computation.

Currently, most organizations are dependent on IS/ICT in order to support their business strategies. IS/ICT can promote the implementation of strategies and enhancers of optimization of the various aspects of the business. In market enterprises and social organizations, digital economy and ICTs are important tools that can empower social entrepreneurship initiatives to develop, fund, and implement new and innovative solutions to social, cultural, and environmental problems. The Handbook of Research on Multidisciplinary Approaches to Entrepreneurship, Innovation, and ICTs is an essential reference source that discusses the digitalization techniques of the modern workforce as well as important tools empowering social entrepreneurship initiatives. Featuring research on topics such as agile business analysis, multicultural workforce, and human resource management, this book is ideally designed for business managers, entrepreneurs, IT consultants, researchers, industry professionals, human resource consultants, academicians, and students.
