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. From the Hardcover edition.

A Washington Post Notable Book In March 1941, after a year of devastating U-boat attacks, the British War Cabinet turned to an intensely private, bohemian physicist named Patrick Blackett to turn the tide of the naval campaign. Though he is little remembered today, Blackett did as much as anyone to defeat Nazi Germany, by revolutionizing the Allied anti-submarine effort through the disciplined, systematic implementation of simple mathematics and probability theory. This is the story of how British and American civilian intellectuals helped change the nature of twentieth-century warfare, by convincing disbelieving military brass to trust the new field of operational research.

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.

A NEW YORK TIMES BESTSELLER The thrilling, true-life account of the FBI’s hunt for the ingenious traitor Brian Regan—known as the Spy Who Couldn’t Spell. Before Edward Snowden’s infamous data breach, the largest theft of government secrets was committed by an ingenious traitor whose intricate espionage scheme and complex system of coded messages were made even more baffling by his dyslexia. His name is Brian Regan, but he came to be known as The Spy Who Couldn’t Spell. In December of 2000, FBI Special Agent Steven Carr of the bureau’s Washington, D.C., office received a package from FBI New York: a series of coded letters from an anonymous sender to the Libyan consulate, offering to sell classified United States intelligence. The offer, and the threat, were all too real. A self-proclaimed CIA analyst with top secret clearance had information about U.S. reconnaissance satellites, air defense systems, weapons depots, munitions factories, and underground bunkers throughout the Middle East. Rooting out the traitor would not be easy, but certain clues suggested a government agent with a military background, a family, and a dire need for money. Leading a diligent team of investigators and code breakers, Carr spent years hunting down a dangerous spy and his cache of stolen secrets. In this fast-paced true-life spy thriller, Yudhijit Bhattacharjee reveals how the FBI unraveled Regan’s strange web of codes to build a case against a man who nearly collapsed America's military security.

During the Cold War, the political leadership of the Soviet Union avidly sought intelligence about its main adversary, the United States. Although effective on an operational level, Soviet leaders and their intelligence chiefs fell short when it came to analyzing intelligence. Soviet leaders were often not receptive to intelligence that conflicted with their existing beliefs, and analysts were reluctant to put forward assessments that challenged ideological orthodoxy. There were, however, important changes over time. Ultimately the views of an enlightened Soviet leader, Gorbachev, trumped the ideological blinders of his predecessors and the intelligence service’s dedication to an endless duel with their ideologically spawned “main adversary," making it possible to end the Cold War. Raymond Garthoff draws on over five decades of personal contact with Soviet diplomats, intelligence officers, military leaders, and scholars during his remarkable career as an analyst, senior diplomat, and historian. He also builds on previous scholarship and examines documents from Soviet and Western archives. Soviet Leaders and Intelligence offers an informed and highly readable assessment of how the Soviets understood—and misunderstood—the intentions and objectives of their Cold War adversary.
