Using science, math, innovation, and improvisation, Bletchley Park code breakers worked furiously to invent a machine to decipher what turned out to be the secrets of Nazi high command. It was called Colossus. What these code breakers didn't realize was that they had fashioned the world's first true computer. When the war ended, this incredible invention was dismantled and hidden away for almost 50 years. Paul Gannon has pieced together the tremendous story of what is now recognized as the greatest secret of Bletchley Park.

    His breaking of the German U-boat Enigma cipher in World War II ensured Allied-American control of the Atlantic. But Turing's vision went far beyond the desperate wartime struggle. Already in the 1930s he had defined the concept of the universal machine, which underpins the computer revolution. In 1945 he was a pioneer of electronic computer design. But Turing's true goal was the scientific understanding of the mind, brought out in the drama and wit of the famous "Turing test" for machine intelligence and in his prophecy for the twenty-first century.Drawn in to the cockpit of world events and the forefront of technological innovation, Alan Turing was also an innocent and unpretentious gay man trying to live in a society that criminalized him. In 1952 he revealed his homosexuality and was forced to participate in a humiliating treatment program, and was ever after regarded as a security risk. His suicide in 1954 remains one of the many enigmas in an astonishing life story.

    Army and Navy and the British government over the last five years. Now, Battle of Wits presents the history of the war that these documents reveal. From the battle of Midway until the last German code was broken in January 1945, this is an astonishing epic of a war that was won not simply by brute strength but also by reading the enemy's intentions. The revelations of Stephen Budiansky's dramatic history include how Britain tried to manipulate the American codebreakers and monopolize German Enigma code communications; the first detailed published explanations of how the Japanese codes were broken; and how the American codebreaking machines worked to crack the Japanese, the German, and even the Russian diplomatic codes. The compelling narrative shows the crucial effect codebreaking had on the battlefields by explaining the urgency of stopping the wolf pack U-boat attacks in the North Atlantic, the importance of halting Rommel's tanks in North Africa, and the necessity of ensuring that the Germans believed the Allies' audacious deception and cover plans for D-Day. Unveiled for the first time, the complete story of codebreaking in World War II has now been told.

    This was to be 'Station X', the Allies' top-secret centre for deciphering enemy codes.Their task was to break the ingenious Enigma cypher used for German high-level communications. The settings for the Enigma machine changed continually and each day the German operators had 159 million million million different possibilities. Yet against all the odds this gifted group achieved the impossible, coping with even greater difficulties to break Shark, the U-Boat Enigma, and Fish, the cypher system used by Hitler to talk to his generals.'Sation X' is also the story of the people involved from leading codebreakers such as Alan Turing, father of the modern computer, to the female operators who intercepted the messages. Through interviews with surviving members of Bletchley Park, Michael Smith has discovered what life was like there. In this chaotic and isolated environment they found time for drama performances, music recitals, orchestras and love affairs.Not only did these people shorten the war by several years - they were essential to victory in the Atlantic and North Africa and to the masterminding of the D-Day landings - 'Station X' was also the birth place of the world's first programmable computer and the successful Anglo-American intelligence partnership.

    It is a testament to the remarkable and mysterious work during World War II that made it a place worth saving. It is a book about campaigners, veterans, enthusiasts, computer geeks, technology, Twitter, trees and Stephen Fry stuck in a lift.And finally, it is a story about preserving the past for the generations of tomorrow.

    Turing’s openness about his homosexuality at a time when it was an imprisonable offense ultimately led to his untimely lo death at the age of only forty-one. In Alan Turing: Unlocking the Enigma, David Boyle reveals the mysteries behind the man and his remarkable career. Aged just 22, Turing was elected a fellow at King's College, Cambridge on the strength of a dissertation in which he proved the central limit theorem. By the age of 33, he had been awarded the OBE by King George VI for his wartime services: Turing was instrumental in cracking the Nazi Enigma machines at the top secret code breaking establishment at Bletchley Park during the Second World War.But his achievements were to be tragically overshadowed by the paranoia of the post-War years. Hounded for his supposedly subversive views and for his sexuality, Turing was prosecuted in 1952, and forced to accept the humiliation of hormone treatment to avoid a prison sentence. Just two years later, at the age of 41 he was dead. The verdict: cyanide poisoning.Was Turing’s death accidental as his mother always claimed? Or did persistent persecution drive him to take him own life?Alan Turing: Unlocking the Enigma seeks to find the man behind the science, illuminating the life of a person who is still a shadowy presence behind his brilliant achievements.

    This country house was home to Britain's most brilliant mathematical brains, like Alan Turing, and the scene of immense advances in technology—indeed, the birth of modern computing. The military codes deciphered there were instrumental in turning both the Battle of the Atlantic and the war in North Africa. But, though plenty has been written about the scientists and the codebreaking, fictional and non-fiction—from Robert Harris and Ian McEwan to Andrew Hodges' biography of Turing—what of the thousands of men and women who lived and worked there during the war? The first history for the general reader of life at Bletchley Park, this is also an amazing compendium of memories from people now in their eighties of skating on the frozen lake in the grounds (a depressed Angus Wilson, the novelist, once threw himself in), of a youthful Roy Jenkins—useless at codebreaking, of the high jinks at nearby accommodation hostels, and of the implacable secrecy that meant girlfriend and boyfriend working in adjacent huts knew nothing about each other's work.

    Britain's Secret Intelligence Service (MI6) was born a century ago amid fears of the rising power of other countries, especially Germany. The next 40 years saw MI6 taking an increasingly important & largely hidden role in shaping history. This revelatory account draws on a wealth of archival materials never before seen by outsiders to unveil the inner workings of the world's 1st spy agency. MI6's early days were haphazard but it was quickly forged into an effective organization during WWI. During the war years, MI6 also formed ties with the USA--harbingers of a relationship that would become vital to both. These early years also saw the development of techniques that would become plot devices in books & films--forgery, invisible ink, disguises, concealing mechanisms etc. The interwar years were nominally peaceful, but Britain perceived numerous threats, all of which MI6 was expected to keep tabs on. The outbreak of WWII again caught MI6 off balance, & high-profile blunders (& the memoirs of MI6 operatives like Graham Greene) created an impression of ineffectiveness. At the same time the service was pioneering cryptography at Bletchley Park, breaking the Enigma code & devising the methods & equipment inspiring Ian Fleming's novels. The aftermath of WWII was as dramatic as the war itself had been, because 1945-49 saw not only the end of the British Empire but also the emergence of a new sort of conflict--the Cold War. We witness MI6 wrestling with these epic changes as it tightens its bonds with the newly christened CIA, changes that would dictate the shape of the service & the world for decades.

    Purpose? To deceive the Nazis into thinking the Allies were planning to attack Europe by way of Greece or Sardinia, rather than Sicily, as the Nazis had assumed & the Allies ultimately chose. Charles Cholmondeley of MI5 & the British naval intelligence officer Ewen Montagu were very different. Cholmondeley was a dreamer seeking adventure. Montagu was an aristocratic, detail-oriented barrister. A perfect team, they created an ingenious plan: equip a corpse with secret (but false) papers concerning the invasion, then drop it off the coast of Spain where German spies would hopefully take the bait. The idea was approved by British intelligence officials, including Ian Fleming (007's creator). Winston Churchill believed it might ring true to the Axis & help bring victory.Filled with spies, double agents, rogues, heroes & a corpse, the story of Operation Mincemeat reads like an international thriller. Unveiling never-before-released material, Macintyre goes into the minds of intelligence officers, their moles & spies, & the German Abwehr agents who suffered the “twin frailties of wishfulness & yesmanship.” He weaves together the eccentric personalities of Cholmondeley & Montagu & their improbable feats into an adventure that saved thousands & paved the way for the conquest of Sicily.

    He was twenty-two. Soon recognized as a cryptographer of genius, he became head of communications at the Special Operations Executive (SOE), where he revolutionized the codemaking techniques of the Allies and trained some of the most famous agents dropped into occupied Europe, including "the White Rabbit" and Violette Szabo. As a top codemaker, Marks had a unique perspective on one of the most fascinating and, until now, little-known aspects of the Second World War. Writing with the narrative flair and vivid characterization of his famous screenplays, Marks gives free rein to his keen sense of the absurd and his wry wit, resulting in a thrilling and poignant memoir that celebrates individual courage and endeavor, without losing sight of the human cost and horror of war.

    Here, unsuspected by the Germans, the famous Enigma codes were broken, almost continuously throughout the war. Welchman was a leading figure at Bletchley Park; his brilliant mathematical mind, and imaginative attack on apparently insuperable problems, were of inestimable value in shaping the course of the war and hastening victory. No other book has explained so thoroughly how the job was done, and how so often a flash of genius, an inspired insight, or even a stroke of luck, tipped the balance from failure to success, against all the odds.Gordon Welchman, a talented mathematician, was educated at Marlborough, and Trinity College, Cambridge. He had taken up a post as a fellow of Sidney Sussex College when the war started, and he was an obvious recruit for the expanding codebreaking operations at Bletchley Park. He was awarded the OBE for his war work. After the war he emigrated to the USA, and continued to work on computers and their applications to security and communications. He died in 1985."A publishing history is given on page 252, in Appendix III: First published by McGraw-Hill Book Co. Inc. in 1982, with a British edition appearing in the same year under the Allen Lane imprint. A paperback edition was published by Penguin Books in 1984.

     Alan Turing had a radical and ingenious mind. He is considered one of the fathers of artificial intelligence, and his theories on this matter range from purely mechanical to almost spiritual. During World War II, his decryption of the Nazis’ Enigma codes proved vital for the Allied victory over the Axis powers. Turing’s fingerprints are everywhere, and yet his own country for quite some time failed to acknowledge it. It wasn’t until 2009 that the then prime minister of the United Kingdom, Gordon Brown, issued an official, posthumous apology to Alan Turing for “the appalling way he was treated.” To many, this was an admission that was far too long in coming. Inside you will read about... ✓ The Death of His First Love ✓ Turing Machines ✓ Breaking the Nazis’ Enigma Codes ✓ Conviction and Chemical Castration ✓ The Poison Apple And much more! As the chronicling of this book demonstrates, Alan Turing’s life was by no means easy; there were hardships, trials, and tribulations that would shake him to his core. But despite the tragic way his life ended by way of a poison apple, the spark ignited by Alan Turing’s short life is still something exceedingly brilliant to behold.

    The cause of their failure was a complete mystery.Five months later, a seemingly unrelated event occurred. A computer security firm in Belarus was called in to troubleshoot some computers in Iran that were caught in a reboot loop—crashing and rebooting repeatedly. At first, technicians with the firm believed the malicious code they found on the machines was a simple, routine piece of malware. But as they and other experts around the world investigated, they discovered a virus of unparalleled complexity and mysterious provenance and intent. They had, they soon learned, stumbled upon the world’s first digital weapon.Stuxnet, as it came to be known, was unlike any other virus or worm built before: It was the first attack that reached beyond the computers it targeted to physically destroy the equipment those computers controlled. It was an ingenious attack, jointly engineered by the United States and Israel, that worked exactly as planned, until the rebooting machines gave it all away. And the discovery of Stuxnet was just the beginning: Once the digital weapon was uncovered and deciphered, it provided clues to other tools lurking in the wild. Soon, security experts found and exposed not one but three highly sophisticated digital spy tools that came from the same labs that created Stuxnet. The discoveries gave the world its first look at the scope and sophistication of nation-state surveillance and warfare in the digital age.Kim Zetter, a senior reporter at Wired, has covered hackers and computer security since 1999 and is one of the top journalists in the world on this beat. She was among the first reporters to cover Stuxnet after its discovery and has authored many of the most comprehensive articles about it. In COUNTDOWN TO ZERO DAY: Stuxnet and the Launch of the World’s First Digital Weapon, Zetter expands on this work to show how the code was designed and unleashed and how its use opened a Pandora’s Box, ushering in an age of digital warfare in which any country’s infrastructure—power grids, nuclear plants, oil pipelines, dams—is vulnerable to the same kind of attack with potentially devastating results. A sophisticated digital strike on portions of the power grid, for example, could plunge half the U.S. into darkness for weeks or longer, having a domino effect on all other critical infrastructures dependent on electricity.

    Banks, telecommunications companies, and critical government networks (including the British Parliament and the French and German military) were infected. No one had ever seen anything like it. By January 2009 the worm lay hidden in at least eight million computers and the botnet of linked computers that it had created was big enough that an attack might crash the world. This is the gripping tale of the group of hackers, researches, millionaire Internet entrepreneurs, and computer security experts who united to defend the Internet from the Conficker worm: the story of the first digital world war.

    A few weeks later a mathematician in Warsaw begins to decipher the coded communications of the Third Reich and lay 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 II. The Polish code-breakers are in France on the run from the Gestapo. People who know the Enigma secret are not supposed to be in the combat zone for fear of capture so MI6 devises a plan to exfiltrate them. If it goes wrong, if they are caught, they could give away the greatest secret of the war. X, Y & Z describes how French, British and Polish secret services came together to unravel the Enigma machine. It tells of how, under the very noses of the Germans, Enigma code-breaking continued in Vichy France. And how code-breakers from Poland continued their work for Her Majesty’s Secret Service, watching the USSR’s first steps of the Cold War. The people of X, Y and Z were eccentric, colorful and caught up in world events that they could watch not control. This is their story…
