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.

Battle of Wits

The Complete Story of Codebreaking in World War II

A million pages of new World War II codebreaking records have been released by the U.S. 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. This is the story of the Allied codebreakers puzzling through the most difficult codebreaking problems that ever existed. At the same time, the compelling narrative shows the crucial effect codebreaking had on the battle-fields by explaining the urgency of stopping the wolf pack U-boat attacks in the North Atlantic, the burning desire in the United States to turn the tide of the war after Pearl Harbor, 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. Budiansky brings to life the unsung code-breaking heroes of this secret war: Joseph J. Rochefort, an intense and driven naval officer who ran the codebreaking operation in "The Dungeon", a dank basement at Pearl Harbor, that effectively won the Battle of Midway; Alan Turing, the eccentric father of the computerage, whose brilliant electromechanical calculators broke the German Enigma machine; and Ian Fleming, whose daredevil espionage schemes to recover codebooks resembled the plots of the 007 novels he later wrote. Among the villains, we meet the Nazi Admiral Donitz, who led the submarine wolf packs against Allied shipping in the North Atlantic with horrific casualty rates -- until the codebreakers stopped him. Budiansky, a Harvard-trained mathematician, demonstrates the mathematical insight and creativity of the cryptographers by showing step-by-step precisely how the codes were broken. This technology -- the flow of information, its encryption, and the computational methods of recovering it from the enemy -- had never before been so important to the outcome of a war. Informative diagrams, maps, appendices, and photographs show exactly how, why, and where the secret war was won. Unveiled for the first time, the complete story of codebreaking in World War II has now been told.

At the height of World War II in the Pacific, two secret organisations existed in Australia to break Japan's military codes. They were peopled by brilliant and idiosyncratic cryptographers, including some with achievements in mathematics and the Classics and others who had lived or grown up in Japan. These men patiently and carefully unravelled the codes in Japanese signals, ultimately playing a crucial role in the battles of Midway and the Coral Sea, as well as Macarthur's push into the Philippines. An intercept station in the Queensland bush brought about the end of Admiral Yamamoto. But this is more than a story of codes. It is an extraordinary exploration of a unique group of men and their intense personal rivalries and loathing, of white-anting and taking credit for others' achievements. It is also the story of a fierce inter-national and inter-service political battle for control of war-changing intelligence between a group of cryptographers based at the Monterey apartment block in Melbourne's Albert Park and General MacArthur's counter group that eventually established its headquarters in suburban Brisbane. What happened between these two groups would have consequences for intelligence services in the years to follow. Code Breakers brings this surprising and very secret world and the men who operated in it to rich life for the first time.

A sweeping, in-depth history of NSA, whose famous "cult of silence" has left the agency shrouded in mystery for decades The National Security Agency was born out of the legendary codebreaking programs of World War II that cracked the famed Enigma machine and other German and Japanese codes, thereby turning the tide of Allied victory. In the postwar years, as the United States developed a new enemy in the Soviet Union, our intelligence community found itself targeting not soldiers on the battlefield, but suspected spies, foreign leaders, and even American citizens. Throughout the second half of the twentieth century, NSA played a vital, often fraught and controversial role in the major events of the Cold War, from the Korean War to the Cuban Missile Crisis to Vietnam and beyond. 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. Featuring a series of appendixes that explain the technical details of Soviet codes and how they were broken, this is a rich and riveting history of the underbelly of the Cold War, and an essential and timely read for all who seek to understand the origins of the modern NSA.

"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."

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.
