The German military used the Geheimschreiber device to encode strategic communications. In 1940 Swedish mathematician Arne Beurling broke the code. Beckman (formerly the head of the cryptanalysis department of the Swedish signal intelligence agency) presents a narrative history of that achievement and other aspects of the Swedish code program that frequently strays into mathematical explanations of the cryptographic issues surrounding the story. Originally published in Swedish as Svenska kryptobedrifter. Annotation copyrighted by Book News, Inc., Portland, OR

Despite publicity given to the successes of British and American codebreakers during the Second World War, the study of signals intelligence is still complicated by governmental secrecy over even the most elderly peacetime sigint. This book, first published in 1986, lifts the veil on some of these historical secrets. Christopher Andrew and Keith Neilson cast new light on how Tsarist codebreakers penetrated British code and cypher systems. John Chapman’s study of German military codebreaking represents a major advance in our understanding of cryptanalysis during the Weimar Republic. The history of the Government Code and Cypher School – forerunner of today’s GCHQ – by its operational head, the late A.G. Denniston, provides both a general assessment of the achievements of British cryptanalysis between the wars and a tantalising glimpse of what historians may one day find in GCHQ’s forbidden archives. The distinguished cryptanalyst of Bletchley Park, the late Gordon Welchman, describes in detail how the Ultra programme defeated the German Enigma machine, while another Bletchley Park cryptographer, Christopher Morris, reminds us in his account of the valuable work on hand cyphers that wartime sigint consisted of much more than Ultra. Roger Austin’s study of surveillance under the Vichy regime shows the continuing importance of older and simpler methods of message interception such as letter-opening. Taken together, the articles establish sigint as an essential field of study for both the modern historian and the political scientist.

The award-winning New York Times bestseller about the American women who secretly served as codebreakers during World War II--a "prodigiously researched and engrossing" (New York Times) book that "shines a light on a hidden chapter of American history" (Denver Post). Recruited by the U.S. Army and Navy from small towns and elite colleges, more than ten thousand women served as codebreakers during World War II. While their brothers and boyfriends took up arms, these women moved to Washington and learned the meticulous work of code-breaking. Their efforts shortened the war, saved countless lives, and gave them access to careers previously denied to them. A strict vow of secrecy nearly erased their efforts from history; now, through dazzling research and interviews with surviving code girls, bestselling author Liza Mundy brings to life this riveting and vital story of American courage, service, and scientific accomplishment.

INTERNATIONAL BESTSELLER Go behind the scenes of Bletchley Park, where everyday men and women risked everything for Queen and Country. A remarkable look at day-to-day life of the codebreakers whose clandestine efforts helped win World War II Bletchley Park looked like any other sprawling country estate. In reality, however, it was the top-secret headquarters of Britain’s Government Code and Cypher School—and the site where Germany’s legendary Enigma code was finally cracked. There, the nation’s most brilliant mathematical minds—including Alan Turing, whose discoveries at Bletchley would fuel the birth of modern computing—toiled alongside debutantes, factory workers, and students on projects of international importance. Until now, little has been revealed about ordinary life at this extraordinary facility. Drawing on remarkable first-hand interviews, The Secret Lives of Codebreakers reveals the entertainments, pastimes, and furtive romances that helped ease the incredible pressures faced by these covert operatives as they worked to turn the tide of World War II.

The highly eccentric Alfred Dillwyn Knox, known simply as 'Dilly', was one of the leading figures in the British codebreaking successes of the two world wars. During the first, he was the chief codebreaker in the Admiralty, breaking the German Navy's main flag code, before going on to crack the German Enigma ciphers during the Second World War at Bletchley Park. Here, he enjoyed the triumphant culmination of his life's work: a reconstruction of the Enigma machine used by the Abwehr, the German Secret Service. This kept the British fully aware of what the German commanders knew about Allied plans, allowing MI5 and MI6 to use captured German spies to feed false information back to the Nazi spymasters. Mavis Batey was one of 'Dilly's girls', the young female codebreakers who helped him to break the various Enigma ciphers. She was called upon to advise Kate Winslet, star of the film Enigma, on what it was like to be one of the few female codebreakers at Bletchley Park. This gripping new edition of Batey's critically acclaimed book reveals the vital part Dilly played in the deception operation that ensured the success of the D-Day landings, altering the course of the Second World War.

The extraordinary wartime exploits of the British codebreakers based at Bletchley Park continue to fascinate and amaze. In The Emperor's Codes Michael Smith tells the story of how Japan's wartime codes were broken, and the consequences for the Second World War. He describes how the Japanese ciphers were broken and the effect on the lives of the codebreakers themselves. Using material from recently declassified British files, privileged access to Australian secret official histories and interviews with British, American and Australian codebreakers, this is the first full account of the critical role played by Bletchley Park and its main outposts around the world.
