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.

STATION X tells the true story, as it has never been told before, of the amazing achievements of the codebreakers working at Bletchley Park in the Second World War.In 1939, several hundred people - students, professors, international chess players, junior military officers, actresses and debutantes - reported to a Victorian mansion in Buckinghamshire: Bletchley Park. This was to be 'Station X', the Allies' top-secret centre for deciphering enemy codes. Their task was to break the ingenious Enigma code 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 guards.

While battalions hunkered down in the mud of western France, anti-aircraft guns took aim at zeppelins floating over the capital, and Atlantic convoys tried desperately to evade German U-boats, another, more secret battle was underway. Down gloomy Whitehall corridors a team of eccentric and pioneering codebreakers were fighting for information that would give them a decisive advantage over the enemy. The new technologies of wireless and telegraph were vital for governments and the military, but vulnerable to interception. Cracking the codes used to protect them quickly became a crucial part of the war effort, and London Room 40, led by the charismatic and cunning ‘Blinker’ Hall, was at the centre of this push for intelligence. Not content to wait for enemy communications to come to him, Hall was soon running agents in other countries, particularly in neutral USA where German saboteurs were intent on damaging the essential flow of munitions to Britain. The stories of Bletchley Park and the spies of the Second World War are well known, but it was Room 40 and their colleagues across the intelligence services that started it all. From the docks of New York City to shady Cairo hotels, this is the gripping and fast-paced story of spies, codebreakers and saboteurs.

Die Fantasie der Menschen beim Schmuggeln geheimer Daten ist nahezu grenzenlos: Ein im Schuhabsatz versteckter Mikrofilm, das Tarnen einer Spionagenachricht als Zigarrenbestellung, das Schreiben mit Geheimtinte, das Verbergen von Daten in harmlosen Bildern und Zinken- Codes – dies sind nur einige von unzähligen Beispielen für versteckte Botschaften. Fachleute bezeichnen dieses Verbergen und Schmuggeln von Nachrichten als "Steganografie". Die Steganografie hat eine faszinierende Geschichte. Bevor die Verschlüsselungstechnik Ende des 19. Jahrhunderts deutliche Fortschritte machte, war das Verstecken einer Nachricht oft wirkungsvoller als das Verschlüsseln. Auch heute noch wendet nahezu jeder Mensch steganografische Techniken an – meist ohne es zu wissen. Nach dem großen Erfolg der ersten Auflage erzählt Klaus Schmeh in seiner überarbeiteten Neuausgabe die faszinierende Geschichte dieser versteckten Botschaften, die von den alten Griechen und ihren Wachstafeln über Geheimoperationen im Kalten Krieg bis zu den Computerhackern der Gegenwart reicht. Er nimmt den Leser mit auf eine furiose Reise durch eine Kulturgeschichte voller Intrigen, Verbrechen und Kriege, in der jedoch auch die Falschspielerei oder der Betrug in der Klassenarbeit eine wichtige Rolle spielen. Die Telepolis-Bücher basieren auf dem Themenkreis des Online-Magazins Telepolis. Die Reihe schaut wie das Online-Magazin über den Tellerrand eingefahrener Abgrenzungen hinaus und erörtert Phänomene der digitalen Kultur und der Wissensgesellschaft. Telepolis finden Sie unter

When the German cruiser Magdeburg ran aground off the Estonian coast in August 1914, little did the British Admiralty realise that what was onboard the ill-fated vessel would hand them a decisive advantage in the battle for North Sea supremacy, and subsequently lead to the birth of the Government Communications Headquarters. Onboard the Magdeburg was a collection of clandestine codebooks and maps, containing coded squares, which offered invaluable clues as to the whereabouts of the German High Seas Fleet. Before long, the codebooks used by German warships, U-Boats and naval zeppelins, and the ciphers used by the Germans to communicate with their naval attachés and embassies, had also fallen into the Admiralty's possession. Having been gifted with such priceless information, Admiral Oliver, the Director of Naval Intelligence, assembled a team comprising the most talented British cryptologists who, by the end of the war, had deciphered over 15,000 German communications. Operating out of their humble base in Room 40 of the Admiralty Headquarters, and led by Alfred Ewing, who constructed ciphers as a hobby, the team played an integral role in the naval engagements during the war, most notably in detecting major German sorties in the North Sea that led to the battles of Dogger Bank and Jutland. This book will profile those who worked within the smoky, claustrophobic confines of Room 40, their sometimes trying relations with one another, as well as analyse the vital parts each member played throughout the conflict. Critically, their knowledge of the infamous Zimmerman Telegram, the U-Boat menace and the tragic and controversial sinking of the Lusitania, placed them, sometimes reluctantly, at the vanguard of all British naval strategy. Several of those in Room 40 would later go on to break the Enigma codes at Bletchley Park during World War 2, however, the contributions made by these modest few during our nation's darkest episode were just as crucial and cannot be underestimated in their importance...

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.

Alan Turing, Enigma ist die Biographie des legendären britischen Mathematikers, Logikers, Kryptoanalytikers und Computerkonstrukteurs Alan Mathison Turing (1912-1954). Turing war einer der bedeutendsten Mathematiker dieses Jahrhunderts und eine höchst exzentrische Persönlichkeit. Er gilt seit seiner 1937 erschienenen Arbeit "On Computable Numbers", in der er das Prinzip des abstrakten Universalrechners entwickelte, als der Erfinder des Computers. Er legte auch die Grundlagen für das heute "Künstliche Intelligenz" genannte Forschungsgebiet. Turings zentrale Frage "Kann eine Maschine denken?" war das Motiv seiner Arbeit und wird die Schlüsselfrage des Umgangs mit dem Computer werden. Die bis 1975 geheimgehaltene Tätigkeit Turings für den britischen Geheimdienst, die zur Entschlüsselung des deutschen Funkverkehrs führte, trug entscheidend zum Verlauf und Ausgang des Zweiten Weltkriegs bei.

The complete story of how the German Enigma codes were broken. Perfect for fans of THE IMITATION GAME, the new film on Alan Turing's Enigma code, starring Benedict Cumberbatch. Breaking the German Enigma codes was not only about brilliant mathematicians and professors at Bletchley Park. There is another aspect of the story which it is only now possible to tell. It takes in the exploits of spies, naval officers and ordinary British seamen who risked, and in some cases lost, their lives snatching the vital Enigma codebooks from under the noses of Nazi officials and from sinking German ships and submarines. This book tells the whole Enigma story: its original invention and use by German forces and how it was the Poles who first cracked - and passed on to the British - the key to the German airforce Enigma. The more complicated German Navy Enigma appeared to them to be unbreakable.

A melting pot of Oxbridge dons, maverick oddballs and more regular citizens worked night and day at Station X, as Bletchley Park was known, to derive intelligence information from German coded messages. Bear in mind that an Enigma machine had a possible 159 million million million different settings and the magnitude of the challenge becomes apparent. That they succeeded, despite military scepticism, supplying information that led to the sinking of the Bismarck, Montgomery’s victory in North Africa and the D-Day landings, is testament to an indomitable spirit that wrenched British intelligence into the modern age, as the Second World War segued into the Cold War. Michael Smith constructs his absorbing narrative around the reminiscences of those who worked and played at Bletchley Park, and their stories add a very human colour to their cerebral activity. The code breakers of Station X did not win the war but they undoubtedly shortened it, and the lives saved on both sides stand as their greatest achievement.
