The magnificent, unrivaled history of codes and ciphers -- how they're made, how they're broken, and the many and fascinating roles they've played since the dawn of civilization in war, business, diplomacy, and espionage -- updated with a new chapter on computer cryptography and the Ultra secret. Man has created codes to keep secrets and has broken codes to learn those secrets since the time of the Pharaohs. For 4,000 years, fierce battles have been waged between codemakers and codebreakers, and the story of these battles is civilization's secret history, the hidden account of how wars were won and lost, diplomatic intrigues foiled, business secrets stolen, governments ruined, computers hacked. From the XYZ Affair to the Dreyfus Affair, from the Gallic War to the Persian Gulf, from Druidic runes and the kaballah to outer space, from the Zimmermann telegram to Enigma to the Manhattan Project, codebreaking has shaped the course of human events to an extent beyond any easy reckoning. Once a government monopoly, cryptology today touches everybody. It secures the Internet, keeps e-mail private, maintains the integrity of cash machine transactions, and scrambles TV signals on unpaid-for channels. David Kahn's The Codebreakers takes the measure of what codes and codebreaking have meant in human history in a single comprehensive account, astonishing in its scope and enthralling in its execution. Hailed upon first publication as a book likely to become the definitive work of its kind, The Codebreakers has more than lived up to that prediction: it remains unsurpassed. With a brilliant new chapter that makes use of previously classified documents to bring the book thoroughly up to date, and to explore the myriad ways computer codes and their hackers are changing all of our lives, The Codebreakers is the skeleton key to a thousand thrilling true stories of intrigue, mystery, and adventure. It is a masterpiece of the historian's art.

Alongside the open conflict of World War II there were other, hidden wars - the wars of communication, in which success depended on a flow of concealed and closely guarded information.Smuggled written messages, secretly transmitted wireless signals, or months of eavesdropping on radio traffic meant operatives could discover in advance what the enemy intended to do. This information was passed on to those who commanded the armies, the fleets and the bomber formations, as well as to the other secret agents throughout the world who were desperately trying to infiltrate enemy lines. Vital information that turned the tide of battle in North African desert and on the Pacific Ocean proved to have been obtained by the time-consuming and unglamorous work of cryptanalysts who deciphered the enemy's coded messages, and coded those for the Allies.From the stuffy huts of Bletchley Park to the battles in the Mediterranean, the French and Dutch Resistance movements and the unkempt radio operatives in Burma, the rarely-seen, outstanding stories collected here reveal the true extent of the 'secret war'.The ongoing need for secrecy for decades after the war meant that the outstanding achievements of wartime cryptanalysts could not be properly recognised.With vivid first-hand accounts and illuminating historical research, VOICES OF THE CODEBREAKERS reveals and finally celebrates the extraordinary accomplishments of these ordinary men and women.

Zivon Marin was one of Russia's top cryptographers until the October Revolution tore apart his world. Forced to flee to England after speaking out against Lenin, Zivon is driven by a growing anger and determined to offer his services to the Brits. But never far from his mind is his brother, whom Zivon fears died in the train crash that separated them.

With exclusive interviews, a Signal Corps veteran tells the full story of how cryptography helped defeat the Axis powers, at Bletchley Park and beyond. For years, the story of the World War II codebreakers was kept a crucial state secret. Even Winston Churchill, himself a great advocate of Britain’s cryptologic program, purposefully minimized their achievements in his history books. Now, though, after decades have passed, the true scope of the British and American cryptographers’ role in the war has come to light. It was a role key to the Allied victory. From the Battle of Britain to the Pacific front to the panzer divisions in Africa, superior cryptography gave the Allies a decisive advantage over the Axis generals. Military intelligence made a significant difference in battle after battle. In Codebreakers’ Victory, veteran cryptographer Hervie Haufler takes readers behind the scenes in this fascinating underground world of ciphers and decoders. This broad view represents the first comprehensive account of codebreaking during World War II. Haufler pulls together years of research, exclusive access to top secret files, and personal interviews to craft a captivating must-read for anyone interested in the behind-the-front intellect and perseverance that went into beating the Nazis and Japan.

The British codebreakers at Bletchley Park are now believed to have shortened the duration of the Second World War by up to two years. During the dark days of 1941, as Britain stood almost alone against the the Nazis, this remarkable achievement seemed impossible. This extraordinary book, originally published as Action This Day, includes descriptions by some of Britain s foremost historians of the work of Bletchley Park, from the breaking ofEnigma and other wartime codes to the invention of modern computing, and its influence on Cold War codebreaking. Crucially, it features personal reminiscences and very human stories of wartime codebreaking from former Bletchley Park codebreakers themselves. This edition includes new material from one of those who was there, making The Bletchley Park Codebreakers compulsive reading.

This unique reference presents 59 biographies of people who were key to the sea services being reasonably prepared to fight the Japanese Empire when the Second World War broke out, and whose advanced work proved crucial. These intelligence pioneers invented techniques, procedures, and equipment from scratch, not only allowing the United States to hold its own in the Pacific despite the loss of most of its Fleet at Pearl Harbor, but also laying the foundation of today’s intelligence methods and agencies.

Here is the ultimate inside history of twentieth-century intelligence gathering and covert activity. Unrivalled in its scope and as readable as any spy novel, A Century of Spies travels from tsarist Russia and the earliest days of the British Secret Service to the crises and uncertainties of today's post-Cold War world, offering an unsurpassed overview of the role of modern intelligence in every part of the globe. From spies and secret agents to the latest high-tech wizardry in signals and imagery surveillance, it provides fascinating, in-depth coverage of important operations of United States, British, Russian, Israeli, Chinese, German, and French intelligence services, and much more. All the key elements of modern intelligence activity are here. An expert whose books have received high marks from the intelligence and military communities, Jeffrey Richelson covers the crucial role of spy technology from the days of Marconi and the Wright Brothers to today's dazzling array of Space Age satellites, aircraft, and ground stations. He provides vivid portraits of spymasters, spies, and defectors--including Sidney Reilly, Herbert Yardley, Kim Philby, James Angleton, Markus Wolf, Reinhard Gehlen, Vitaly Yurchenko, Jonathan Pollard, and many others. Richelson paints a colorful portrait of World War I's spies and sabateurs, and illuminates the secret maneuvering that helped determine the outcome of the war on land, at sea, and on the diplomatic front; he investigates the enormous importance of intelligence operations in both the European and Pacific theaters in World War II, from the work of Allied and Nazi agents to the "black magic" of U.S. and British code breakers; and he gives us a complete overview of intelligence during the length of the Cold War, from superpower espionage and spy scandals to covert action and secret wars. A final chapter probes the still-evolving role of intelligence work in the new world of disorder and ethnic conflict, from the high-tech wonders of the Gulf War to the surprising involvement of the French government in industrial espionage. Comprehensive, authoritative, and addictively readable, A Century of Spies is filled with new information on a variety of subjects--from the activities of the American Black Chamber in the 1920s to intelligence collection during the Cuban missile crisis to Soviet intelligence and covert action operations. It is an essential volume for anyone interested in military history, espionage and adventure, and world affairs.
