Published in association with The Turing Trust, this incredible collection of puzzles allows you to put your codebreaking skills to the test - if you can solve every puzzle in the book you might once have been recruited to join the ranks of Alan Turing and the Bletchley Park codebreakers! Alan Turing is often called the father of modern computing. During the Second World War, he worked at Bletchley Park where top-secret work was carried out to decipher the military codes. Turing played a pivotal role in cracking their intercepted coded messages and helping the Allies win the war. This collection contains an incredible range of different puzzle types and so presents a wonderfully entertaining challenge for any puzzle lover. The puzzles are arranged into five levels of difficulty which become progressively harder, so you can start with the (relatively) easy ones and build up to the truly expert level tests. There is even a hint section to help you on your way. Includes: - Anagrams - Logic puzzles - Homonym tests - Number encryption The Turing Trust was set up in 2009 by Alan Turing's closest family and is proud to be able to commemorate his remarkable contribution to the early years of computing and to contribute to the future of computer science by supporting people in rural African communities to become computer literate. The foreword to the book is written Sir Dermot Turing, Alan Turing's nephew and a trustee of The Turing Trust.

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.

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.

In Code Warriors, Stephen Budiansky--a longtime expert in cryptology--tells the fascinating story of how NSA came to be, from its roots in World War II through the fall of the Berlin Wall. Along the way, he guides us through the fascinating challenges faced by cryptanalysts, and how they broke some of the most complicated codes of the twentieth century. With access to new documents, Budiansky shows where the agency succeeded and failed during the Cold War, but his account also offers crucial perspective for assessing NSA today in the wake of the Edward Snowden revelations. Budiansky shows how NSA's obsession with recording every bit of data and decoding every signal is far from a new development; throughout its history the depth and breadth of the agency's reach has resulted in both remarkable successes and destructive failures.
