Douglas R. Stinson's Cryptography: Theory and Practice is a mathematically intensive examination of cryptography, including ciphers, the Data Encryption Standard (DES), public key cryptography, one-way hash functions, and digital signatures. Stinson's explication of "zero-sum proofs"--a process by which one person lets another person know that he or she has a password without actually revealing any information--is especially good. If you are new to the math behind cryptography but want to tackle it, the author covers all of the required background to understand the real mathematics here. Cryptography includes extensive exercises with each chapter and makes an ideal introduction for any math-literate person willing to get acquainted with this material.

Alan Turing, pioneer of computing and World War II code breaker, was one of the most important and influential thinkers of the twentieth century. In this book, Turing's work... is made easily accessible for the first time...This volume contains the work of a genius who, in his all too short life, made significant contributions in important areas benefiting us today.

Cryptography is an outstanding book that covers all the major areas of cryptography in a readable, mathematically precise form. Several chapters deal with especially active areas of research and give the reader a quick introduction and overview of the basic results in the area. Cryptography provides the mathematical theory that is necessary in order to understand how the various systems work. Most algorithms are presented in the form of pseudocode, together with examples and informal discussion of the underlying ideas. The book gives careful and comprehensive treatment of all the essential core areas of cryptography. Also, several chapters present recent topics that have not received thorough treatment in previous textbooks. Such topics include authentication codes, secret sharing schemes, identification schemes, and key distribution. Amazon.

People love secrets. Ever since the first word was written, humans have sent coded messages to each other. In The Code Book, Simon Singh, author of the bestselling Fermat's Enigma, offers a peek into the world of cryptography and codes, from ancient texts through computer encryption. Singh's compelling history is woven through with stories of how codes and ciphers have played a vital role in warfare, politics, and royal intrigue. The major theme of The Code Book is what Singh calls "the ongoing evolutionary battle between codemakers and codebreakers," never more clear than in the chapters devoted to World War II. Cryptography came of age during that conflict, as secret communications became critical to both sides' success.
Confronted with the prospect of defeat, the Allied cryptanalysts had worked night and day to penetrate German ciphers. It would appear that fear was the main driving force, and that adversity is one of the foundations of successful codebreaking.

This really is a terrific book if you're at all interested in learning how to secure information. It's very well-written in a clear, *concise* manner. Two great introductory chapters lay out the fundamentals of cryptography and OpenPGP in plain English. There's nice coverage on terminology, the differences between OpenPGP/PGP/GPG, and the basics of using them.

Since the appearance of the authors' first volume on elliptic curve cryptography in 1999 there has been tremendous progress in the field. In some topics, particularly point counting, the progress has been spectacular. Other topics such as the Weil and Tate pairings have been applied in new and important ways to cryptographic protocols that hold great promise.

The content industries consider Digital Rights Management (DRM) to contend with unauthorized downloading of copyrighted material, a practice that costs artists and distributors massively in lost revenue. Based on two conferences that brought together high-profile specialists in this area - scientists, lawyers, academics, and business practitioners - this book presents a broad, well-balanced, and objective approach that covers the entire DRM spectrum. Reflecting the interdisciplinary nature of the field, the book is structured using three different perspectives that cover the technical, legal, and business issues.

Whether you need to quickly come up to speed on the state of the art in digital watermarking or want to explore the latest research in this area, such as 3-D geometry watermarking, this timely reference gives you the hands-on knowledge you need for your work. This book covers the full range of media -- still images, audio data, video, 3-D geometry data, formatted text, music scores, and program code -- that you can protect with digital watermarking.

Grade 9 UpAA thorough introduction to the history of cryptology that explains the fundamental concepts of this science. Newton provides concise, easy-to-read definitions of terms, topics, and personalities pertinent to the history of encoded messages. Entries are arranged alphabetically and often include cross-references and suggestions for further reading. Black-and-white illustrations, photographs, and charts assist in the comprehension of terms. While there are many books aimed at certain aspects of this topic, none of them do as good a job of presenting a comprehensive yet accessible overview of secret-message writing throughout ancient and modern times.

In today's unsafe and increasingly wired world cryptology plays a vital role in protecting communication channels, databases, and software from unwanted intruders. This revised and extended third edition of the classic reference work on cryptology now contains many new technical and biographical details. The first part treats secret codes and their uses - cryptography. The second part deals with the process of covertly decrypting a secret code - cryptanalysis, where particular advice on assessing methods is given.

Number theory and algebra play an increasingly significant role in computing and communications, as evidenced by the striking applications of these subjects to such fields as cryptography and coding theory. This introductory book emphasises algorithms and applications, such as cryptography and error correcting codes, and is accessible to a broad audience. The mathematical prerequisites are minimal: nothing beyond material in a typical undergraduate course in calculus is presumed, other than some experience in doing proofs - everything else is developed from scratch. Thus the book can serve several purposes. It can be used as a reference and for self-study by readers who want to learn the mathematical foundations of modern cryptography. It is also ideal as a textbook for introductory courses in number theory and algebra, especially those geared towards computer science students.
