Synopsis

This textbook forms an introduction to codes, cryptography and information theory as it has developed since Shannon's original papers. The first part of the book develops the fundamental ideas of information theory, efficient encoding of messages, and error-correcting codes. In later chapters, the author discusses mathematical models of natural languages and the classic Shannon model of cryptography, before surveying computational complexity and the modern cryptographic methods such as public-key cryptography, password systems and authentication techniques. The book is based on courses given to undergraduate mathematicians and computer scientists at the University of Oxford and contains exercises and solutions.

Review

' This excellent book can be strongly recommended... it is so well written that it could be read solely for interest and enjoyment.' Times Higher Educ. Supplement

'This authoritative book has a well structured approach. ...essential reading for the engineer concerned with safe-guarding as well as communicating information.' IEE Review

' an exciting introduction to codes and cryptography,but also manages to provide clear introductory accounts to a number of vitally important and closely related mathematical topics the most significant of which is computational complexity...It is surprising that a book can contain such a high rate of information per page and still be readable...This excellent book can be strongly recommended to anyone with the appropriate mathematical background.'Times Higher Education Supplement
