In his first book since the bestselling Fermat's Enigma, Simon Singh offers the first sweeping history of encryption, tracing its evolution and revealing the dramatic effects codes have had on wars, nations, and individual lives. From Mary, Queen of Scots, trapped by her own code, to the Navajo Code Talkers who helped the Allies win World War II, to the incredible (and incredibly simple) logisitical breakthrough that made Internet commerce secure, The Code Book tells the story of the most powerful intellectual weapon ever known: secrecy. Throughout the text are clear technical and mathematical explanations, and portraits of the remarkable personalities who wrote and broke the world's most difficult codes. Accessible, compelling, and remarkably far-reaching, this book will forever alter your view of history and what drives it. It will also make you wonder how private that e-mail you just sent really is.

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.

Alan Turing, Enigma ist die Biographie des legendAren britischen Mathematikers, Logikers, Kryptoanalytikers und Computerkonstrukteurs Alan Mathison Turing (1912-1954). Turing war einer der bedeutendsten Mathematiker dieses Jahrhunderts und eine hAchst exzentrische PersAnlichkeit. 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 fA1/4r das heute "KA1/4nstliche Intelligenz" genannte Forschungsgebiet. Turings zentrale Frage "Kann eine Maschine denken?" war das Motiv seiner Arbeit und wird die SchlA1/4sselfrage des Umgangs mit dem Computer werden. Die bis 1975 geheimgehaltene TAtigkeit Turings fA1/4r den britischen Geheimdienst, die zur EntschlA1/4sselung des deutschen Funkverkehrs fA1/4hrte, trug entscheidend zum Verlauf und Ausgang des Zweiten Weltkriegs bei.

What would our world today be like without inventions like tarmac, aspirin, liquid crystals, and barbed wire? This guide shows how patents and the inventions they describe have shaped the 21st century. It gives us insights into the inventions, big and small, that have had huge impacts, many unexpected, on multiple spheres of our lives, from popular culture and entertainment, to global health, to transportation, to the waging of war. It features patent documents that date from the mid-19th century to the present. Patent documents describe inventions and represent an accurate and rich source of information about the history and current state of modern technology, as patents are examined and their accuracy can be challenged. The subject matter covers many technical areas. Patents discussed include, for example, Morse code, the diode, triode, transistors, television, frozen foods, ring-pull for soft drink cans, board games such as Monopoly, gene editing, metamaterials, MRI, computerised tomography, insulin, and monoclonal antibodies such as Herceptin. The text is illustrated with drawings adapted from the original patent documents. Patent numbers are included to allow interested readers to trace the documents. Inventions described in the patents are placed in historical perspective. For example, the book discusses the role of the cavity magnetron and radar in World War II, and the influence of the diode on the development of broadcasting at the beginning of the 20th century.

'No wonder that Churchill described this effort as "Britain's secret weapon," a weapon far more effective than the buzz bombs and the rockets that Wernher von Braun designed for a German victory, a weapon absolutely decisive, in the judgement of many, in winning the war for the Allies.' Peter Hilton, mathematician and codebreaker, 1923-2010, about the team at Bletchley Park The Story of Codebreaking begins with the hieroglyphics of Ancient Egypt and weaves its way stealthily through history to the present day, where computer code is fundamental to all of our online activities. It is a tale of ordinary people rising to the challenge of extraordinary circumstances and shows how, through a combination of intelligence, grit, hard work and (occasionally) sheer good fortune, codebreakers have often saved lives and sometimes even changed the course of history. Find out how Mary Queen of Scots smuggled cryptic messages to her accomplices when she was plotting against her cousin Elizabeth I, or discover the methods used by codebreakers during World Wars I and II, most significantly those who cracked Enigma and intercepted Japanese naval messages prior to Pearl Harbor. The sheer doggedness of those who unravelled the Enigma code is thought to have shortened World War II by almost two years. To break a code, you have to put yourself in the mind of your enemy in order to probe the strengths and weaknesses of their systems. It's a game of bluff and doublebluff. The Story of Codebreaking describes undercover operations, power struggles, secret alliances, and brilliant feats of teamwork. Those who invent codes and those who break them are remarkable, indefatigable characters. This is their story. Topics include: Ancient ciphers and the art of encoding Early spies, subterfuge and skytales The making and breaking of Enigma Japanese naval codes in World War II Cold War cryptography
