Codes: The Guide to Secrecy From Ancient to Modern Times

This book explores the depth and breadth of the field of cryptology. It begins by tracing the development of cryptology from inception to modern-day practice. The remainder of the book explores the modern aspects and applications of cryptography, covering symmetric- and public-key cryptography, cryptographic protocols, key management, message authentication, e-mail and Internet security, and advanced applications. Nearly 200 diagrams, examples, figures, and tables along with abundant references and exercises complement the discussion. It is designed such that the non-professional reader may learn all aspects of secrecy yet it is still suitable as a textbook for a course on a variety of secrecy-related topics.
