Codes and Ciphers: Julius Caesar, the Enigma, and the Internet by R.F. Churchhou

Description: Codes and Ciphers by R.F. Churchhouse The design of code and cipher systems has undergone major changes in modern times, not least due to the advent of e-commerce. This book will appeal to anyone interested in codes and ciphers as used by private individuals, spies, governments and industry throughout history. FORMAT Hardcover LANGUAGE English CONDITION Brand New Publisher Description The design of code and cipher systems has undergone major changes in modern times. Powerful personal computers have resulted in an explosion of e-banking, e-commerce and e-mail, and as a consequence the encryption of communications to ensure security has become a matter of public interest and importance. This book describes and analyses many cipher systems ranging from the earliest and elementary to the most recent and sophisticated, such as RSA and DES, as well as wartime machines such as the ENIGMA and Hagelin, and ciphers used by spies. Security issues and possible methods of attack are discussed and illustrated by examples. The design of many systems involves advanced mathematical concepts and this is explained in detail in a major appendix. This book will appeal to anyone interested in codes and ciphers as used by private individuals, spies, governments and industry throughout history and right up to the present day. Author Biography Robert Churchhouse is Emeritus Professor of Computing Mathematics at Cardiff University and has lectured widely on mathematics and cryptanalysis at more than 50 Universities and Institutes throughout the the world. He is also the co-author of books on computers in mathematics, computers in literary and linguistic research, and numerical analysis. Table of Contents Preface; 1. Introduction; 2.
