    This textbook presents a fascinating review of cryptography and cryptanalysis, from the earliest known cryptographic systems of 2,500 years ago up to modern computer-based systems.The text relates the earliest use of the monoalphabetic cipher in the ancient world, the development of the ¿unbreakable¿ Vigenère cipher, and an account of how cryptology entered the arsenal of military intelligence during the American Revolutionary War. Moving on to the American Civil War, the book explains the solution of the Vigenère ciphers used by the Confederates and the use of telegraph codes, before investigating the development of cipher machines throughout World War I and II, including development of the first digital computer, Colossus. The exposition then explores cryptology in the computer age, from public-key cryptography and web security to criminal cyber-attacks and cyber-warfare. The role of cryptography in the Internet of Things is also discussed, along with the potential impact of quantum computing.Topics and features: Presents a history of cryptology from ancient Rome to the present day, with a focus on cryptology in the 20th and 21st centuries Provides engaging examples illustrating use of cryptographic algorithms in different historical periods Reviews algorithms and devices used to create secret messages, and the various methods for breaking such messages Describes notable contributions to cryptology by Herbert Yardley, William and Elizebeth Smith Friedman, Lester Hill, Agnes Meyer Driscoll, and Claude Shannon Examines unsolved mysteries in cryptology, such as the Voynich Manuscript, the Beale Ciphers, the Kryptos sculpture, and the Zodiac killer ciphersThis engaging work is ideal as both a primary text for courses on the history of cryptology, and as a supplementary text for advanced undergraduate courses on cryptology and computer security. No prior background in mathematics is assumed, beyond what would be encountered in an introductory course on discrete mathematics.

    In May 1917, William and Elizebeth Friedman were asked by the U.S. Army to begin training officers in cryptanalysis and to decrypt intercepted German diplomatic and military communications. In June 1917, Herbert Yardley convinced the new head of the Army¿s Military Intelligence Division to create a code and cipher section for the Army with himself as its head. These two seminal events were the beginning of modern American cryptology, the growth of which culminated 35 years later with the creation of the National Security Agency. Each running their own cryptologic agencies in the 1920s, the Friedman-Yardley relationship was shattered after Yardley published a tell-all book about his time in military intelligence. Yet in the end, the work they all started in 1917 led directly to the modern American intelligence community. As they got older, they became increasingly irrelevant in the burgeoning American cryptologic fraternity. Topics and features:* Examines the lives of three remarkable and pioneering cryptologists* Offers fascinating insights into spies, codes and ciphers, rumrunners, poker, and military history* Sheds new light on interesting parts of the cryptologists¿ careers¿especially Elizebeth Friedman, whose work during World War II has just begun to be explored* Recounts several good stories, i.e., What if the Friedmans had gone to work for Herbert Yardley in his new Cipher Bureau in 1919? What if Yardley had moved back to Washington to work for William Friedman a decade later? This enjoyable book has wide appeal for: general readers interested in the evolution of American cryptology, American historians (particularly of World War I, the inter-war period, and World War II signals intelligence), and historians of¿and general readers interested in¿American military intelligence. It also can be used as an auxiliary text or recommended reading in introductory or survey courses in history or on the related topics.

    For over 2,000 years, the desire to communicate securely and secretly has resulted in the creation of numerous and increasingly complicated systems to protect one's messages. Yet for every system there is a cryptanalyst creating a new technique to break that system.
