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.

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

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.

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.

A definitive book on digital signatures, written by experts from RSA Security/ The authors discuss the four main goals of security detail: confidentiality, authentication, integrity and non-repudiation.
