Book excerpt: December, 1932 In the bathroom of a Belgian hotel, a French spymaster photographs top-secret documents – the operating instructions of the cipher machine, Enigma. A few weeks later a mathematician in Warsaw begins to decipher the coded communications of the Third Reich and lays the foundations for the code-breaking operation at Bletchley Park. The co-operation between France, Britain and Poland is given the cover-name 'X, Y & Z'. December, 1942 It is the middle of World War Two. The Polish code-breakers have risked their lives to continue their work inside Vichy France, even as an uncertain future faces their homeland. Now they are on the run from the Gestapo. People who know the Enigma secret are not supposed to be in the combat zone, so MI6 devises a plan to exfiltrate them. If it goes wrong, if they are caught, the consequences could be catastrophic for the Allies. Based on original research and newly released documents, X, Y & Z is the exhilarating story of those who risked their lives to protect the greatest secret of World War Two.

Download or read book Solving the Enigma History of the Cryptanalytic Bombe written by Jennifer Wilcox and published by CreateSpace. This book was released on 2012-08-07 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the German military grew in the late 1920s, it began looking for a better way to secure its communications. It found the answer in a new cryptographic machine called "Enigma." The Germans believe the encryption generated by the machine to be unbreakable. With a theoretical number of ciphering possibilities of 3 x 10114 their belief was not unjustified. However, they never reached that theoretical level of security. Nor did they count on the cryptanalytic abilities of their adversaries. This publication provides a history of this cryptanalytic bombe.

Download or read book Seizing the Enigma written by David Kahn and published by Frontline Books. This book was released on 2012-02-02 with total page 513 pages. Available in PDF, EPUB and Kindle. Book excerpt: “An absorbing and thoroughly well documented account” of WWII naval intelligence and the Allied hunt for the Nazi code machine known as the Enigma (Warship). From the start of World War II to mid-1943, British and American naval forces fought a desperate battle against German submarine wolfpacks. And the Allies might have lost the struggle at sea without an astounding intelligence coup. Here, the author brings to life the race to break the German U-boat codes. As the Battle of the Atlantic raged, Hitler’s U-boats reigned. To combat the growing crisis, ingenious amateurs joined the nucleus of dedicated professionals at Bletchley Park to unlock the continually changing German naval codes. Their mission: to read the U-boat messages of Hitler’s cipher device, the Enigma. They first found success with the capture of U-110,—which yielded the Enigma machine itself and a trove of secret documents. Then the weather ship Lauenburg seized near the Arctic ice pack provided code settings for an entire month. Finally, two sailors rescued a German weather cipher that enabled the team at Bletchley to solve the Enigma after a year-long blackout. In “a highly recommended account with a wealth of materials” Seizing the Enigma tells the story of a determined corps of people who helped turn the tide of the war (Naval Historical Foundation).

Download or read book Alan Turing The Enigma written by Andrew Hodges and published by Princeton University Press. This book was released on 2014-11-10 with total page 768 pages. Available in PDF, EPUB and Kindle. Book excerpt: A NEW YORK TIMES BESTSELLER The official book behind the Academy Award-winning film The Imitation Game, starring Benedict Cumberbatch and Keira Knightley It is only a slight exaggeration to say that the British mathematician Alan Turing (1912-1954) saved the Allies from the Nazis, invented the computer and artificial intelligence, and anticipated gay liberation by decades--all before his suicide at age forty-one. This New York Times–bestselling biography of the founder of computer science, with a new preface by the author that addresses Turing's royal pardon in 2013, is the definitive account of an extraordinary mind and life. Capturing both the inner and outer drama of Turing’s life, Andrew Hodges tells how Turing’s revolutionary idea of 1936--the concept of a universal machine--laid the foundation for the modern computer and how Turing brought the idea to practical realization in 1945 with his electronic design. The book also tells how this work was directly related to Turing’s leading role in breaking the German Enigma ciphers during World War II, a scientific triumph that was critical to Allied victory in the Atlantic. At the same time, this is the tragic account of a man who, despite his wartime service, was eventually arrested, stripped of his security clearance, and forced to undergo a humiliating treatment program--all for trying to live honestly in a society that defined homosexuality as a crime. The inspiration for a major motion picture starring Benedict Cumberbatch and Keira Knightley, Alan Turing: The Enigma is a gripping story of mathematics, computers, cryptography, and homosexual persecution.

Download or read book German Cipher Machines of World War II written by David Mowry and published by CreateSpace. This book was released on 2012-08-07 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Along with breaking the Japanese diplomatic cryptosystem, usually referred to as "PURPLE," probably the greatest example of Allied cryptanalytic success in World War II was breaking of the German Enigma machine. This cryptodevice was used by all of the German armed forces as the primary cryptosystem for all units below Army level or the equivalent. As D-Day approached, other German cryptodevices, the SZ-42 and the various T-52 machines, assumed great importance since they were used by the higher commands of the German armed forces. Many references to these German machines in the histories fail to provide information on what they looked like or how they worked. Another group of cryptodevices, those invented by Fritz Menzer for the Abwehr (Counterintelligence), have received little or no notice in the literature and are unknown to the public. This brochure is an attempt to remedy both lacks.

Download or read book Lorenz written by Jerry Roberts and published by The History Press. This book was released on 2017-03-02 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: The breaking of the Enigma machine is one of the most heroic stories of the Second World War and highlights the crucial work of the codebreakers of Bletchley Park, which prevented Britain's certain defeat in 1941. But there was another German cipher machine, used by Hitler himself to convey messages to his top generals in the field. A machine more complex and secure than Enigma. A machine that could never be broken. For sixty years, no one knew about Lorenz or 'Tunny', or the determined group of men who finally broke the code and thus changed the course of the war. Many of them went to their deaths without anyone knowing of their achievements. Here, for the first time, senior codebreaker Captain Jerry Roberts tells the complete story of this extraordinary feat of intellect and of his struggle to get his wartime colleagues the recognition they deserve. The work carried out at Bletchley Park during the war to partially automate the process of breaking Lorenz, which had previously been done entirely by hand, was groundbreaking and is recognised as having kick-started the modern computer age.

Download or read book The Grand Alliance written by Winston S. Churchill and published by RosettaBooks. This book was released on 2010-06-30 with total page 827 pages. Available in PDF, EPUB and Kindle. Book excerpt: The British, Soviets, and Americans unite in this chapter of the six-volume WWII history by the legendary prime minister and Nobel Prize recipient. The Grand Alliance describes the end of an extraordinary period in British military history, in which Britain stood alone against Germany. Two crucial events brought an end to Britain’s isolation. First was Hitler’s decision to attack the Soviet Union, opening up a battle front in the East and forcing Stalin to look to the British for support. The second was the bombing of Pearl Harbor. US support had long been crucial to the British war effort, and here, Winston Churchill documents his efforts to draw the Americans to aid, including correspondence with President Roosevelt. This book is part of the six-volume account of World War II told from the unique viewpoint of a British prime minister who led his nation in the fight against tyranny. In addition to the correspondence with FDR, the series is enriched with extensive primary sources. We are presented with not only Churchill’s retrospective analysis of the war, but also memos, letters, orders, speeches, and telegrams, day-by-day accounts of reactions as the drama intensifies. Throughout these volumes, we listen as strategies and counterstrategies unfold in response to Hitler’s conquest of Europe, planned invasion of England, and assault on Russia, in a mesmerizing account of the crucial decisions made as the fate of the world hangs in the balance. “A masterly piece of historical writing . . . complete with humor and wit.” —The New Yorker

Available in PDF, EPUB and Kindle. Book excerpt: From cell phones to Web portals, advances in information and communications technology have thrust society into an information age that is far-reaching, fast-moving, increasingly complex, and yet essential to modern life. Now, renowned scholar and author David Luenberger has produced Information Science, a text that distills and explains the most important concepts and insights at the core of this ongoing revolution. The book represents the material used in a widely acclaimed course offered at Stanford University. Drawing concepts from each of the constituent subfields that collectively comprise information science, Luenberger builds his book around the five "E's" of information: Entropy, Economics, Encryption, Extraction, and Emission. Each area directly impacts modern information products, services, and technology--everything from word processors to digital cash, database systems to decision making, marketing strategy to spread spectrum communication. To study these principles is to learn how English text, music, and pictures can be compressed, how it is possible to construct a digital signature that cannot simply be copied, how beautiful photographs can be sent from distant planets with a tiny battery, how communication networks expand, and how producers of information products can make a profit under difficult market conditions. The book contains vivid examples, illustrations, exercises, and points of historic interest, all of which bring to life the analytic methods presented: Presents a unified approach to the field of information science Emphasizes basic principles Includes a wide range of examples and applications Helps students develop important new skills Suggests exercises with solutions in an instructor's manual
