Cryptology, the art and science of 'secret writing', provides ideal methods to solve the problems of transmitting information secretly and securely. The first half of this book studies and analyzes classical cryptosystems. The second half looks at the exciting new directions of public-key cryptology. The book is fun to read, and the author presents the material clearly and simply. Many exercises and references accompany each chapter.

The Encyclopedia of Cryptology addresses the basic theoretical concepts and provides a broad overview of the writing, sending, protection, and decrypting of codes and ciphers. This volume also includes biographical sketches, important events in the history of cryptography, and discussions of the practical applications of codes in everyday life.Illustrations, bibliographic references, and cross-references, plus two indexes complement the text.

This book introduces a wide range of up-to-date cryptological concepts along with the mathematical ideas that are behind them. The new and old are organized around a historical framework. A variety of mathematical topics that are germane to cryptology (e.g., modular arithmetic, Boolean functions, complexity theory, etc.) are developed, but they do not overshadow the main focus of the book. Chapter topics cover origins, examples, and ideas in cryptology; classical cryptographic techniques; symmetric computer-based cryptology; public-key cryptography; and present practice, issues, and the future. For individuals seeking an up-close and accurate idea of how current-day cryptographic methods work.

The author includes not only information about the most important advances in the field of cryptology of the past decade-such as the Data Encryption Standard (DES), public-key cryptology, and the RSA algorithm-but also the research results of the last three years: the Shamir, the Lagarias-Odlyzko, and the Brickell attacks on the Knapsack methods; the new Knapsack method using Galois fields by Chor and Rivest; and the recent analysis by Kaliski, Rivest, and Sherman of group-theoretic properties of the Data Encryption Standard (DES).

Foreword by William J. PerryMost of us experience the interactions of cryptography, communications, and computers as we go about our daily activities. While on our laptops, we conduct secure financial transactions and communicate about business and personal matters. But not long ago, only people with special security clearances working at secured communications centers had such access. This book looks at how this dramatic transition came about.J. V. Boone presents a historical overview of technological developments in cryptology and the closely associated fields of communications and computers. Having directed research at the National Security Agency (NSA) for years, he is well suited to tell the story. Boone identifies milestone accomplishments and activities in the three fields to provide an introduction to the talented people who have led developments and applications. He includes illustrations to give a feel for the equipment and systems, but his book's focus is on the essential ingredient for success in cryptology: brainpower. Everyone from high school students to policy developers in government and industry will be drawn to this concise history of the joint progress of cryptology, communications, and computers. Although he writes primarily from a military intelligence and command/control viewpoint, there are no involved explanations about how individual pieces of equipment function and no elaborate mathematical presentations. For those whose curiosity he has stimulated, he provides additional references.

One of the core technologies that protects cyberspace, cryptology is also intellectually stimulating and fun. This is the only book available that combines classical and contemporary methods of cryptology with a historical perspective. Encourages readers to explore their strengths and weaknesses as they experiment with various ciphers. Features seamless integration between the book's material and accompanying software package (CAP), which enables readers to experiment with the concepts discussed. Covers the practical use of a stream cipher. Uses Block Ciphers in a network, presenting another case where readers are introduced to the actual use of a cipher system. Offers charts at the end of each chapter that show how the new ciphers covered in that chapter fit into the entire classification scheme of cipher systems, helping readers understand the interrelationships which exist between ciphers. A useful and interesting reference for network security professionals.

For historians and many members of the informed public, the Japanese attack on Hawaii provoked “the never-ending story.” Multiple official investigations and private historical inquiries into the attack and its background have generated enormous stocks of information about both the American and Japanese sides. It may well be that we know as much about December 7, 1941, as we do about any event in the last century, the Kennedy assassination possibly excepted. However, even with this virtual mountain chain of data, information gaps still exist, and many important questions remain under discussion or debate. The discussions and debates are not simply the province of conspiracy buffs. Academics and other researchers interested in World War II have a serious stake in settling the issues of the U.S.-Japan conflict; definite answers to many of the controversies would either confirm or refute theories of the war’s origins and its meaning. This assemblage of documents, supplemented by the author’s clear guide to their meaning, places the reader, as it were, right in the middle of the behind-the-scenes events and helps the scholar and researcher to follow them closely.
