Codes

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.
