Description: Codes and Cryptography by Dominic WelshISBN: 0-19-853287-3 This text unifies the concepts of information, codes, and cryptography as first studied by Shannon in his seminal papers on communication and secrecy systems. The book has been the basis of a very popular course in Communication Theory which the author has given over several years to undergraduate mathematicians and computer scientists at Oxford. The first five chapters of the book cover the fundamental ideas of information theory, compact encoding of messages, and an introduction to the theory of error-correcting codes. After a discussion of mathematical models of English and other natural languages there is an introduction to the classical Shannon model of cryptography. This is followed by a brief discussion of the one-time pad, shift registers, and a survey of those aspects of computational complexity needed for an understanding of modern cryptographic methods and their applications to the recent advances in public-key cryptography, password systems, and authentication techniques. Because the aim of the text is to make this exciting branch of modern applied mathematics available to readers with a wide variety of interests and backgrounds, the mathematical prerequisites have been kept to an absolute minimum. Despite this, because of the subject's very recent development the reader is led quickly to the frontiers of present-day research. In addition to an extensive bibliography, there are many exercises (easy) and problems together with solutions. Book Condition: The book is in good condition, with some wear and tear on the cover. The top right corner of the cover is slightly bent and there are minor indentations on the bottom edge of the front cover. The inside pages are in excellent condition, with no markings on the inside pages. The binding is in excellent condition. Part of the proceeds from the sale of this book go to charity.
