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 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.

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.

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.

Every president has had a unique and complicated relationship with the intelligence community. While some have been coolly distant, even adversarial, others have found their intelligence agencies to be among the most valuable instruments of policy and power. Since John F. Kennedy's presidency, this relationship has been distilled into a personalized daily report: a short summary of what the intelligence apparatus considers the most crucial information for the president to know that day about global threats and opportunities. This top–secret document is known as the President's Daily Brief, or, within national security circles, simply “the Book.” Presidents have spent anywhere from a few moments (Richard Nixon) to a healthy part of their day (George W. Bush) consumed by its contents; some (Bill Clinton and George H. W. Bush) consider it far and away the most important document they saw on a regular basis while commander in chief. The details of most PDBs are highly classified, and will remain so for many years. But the process by which the intelligence community develops and presents the Book is a fascinating look into the operation of power at the highest levels. David Priess, a former intelligence officer and daily briefer, has interviewed every living president and vice president as well as more than one hundred others intimately involved with the production and delivery of the president's book of secrets. He offers an unprecedented window into the decision making of every president from Kennedy to Obama, with many character–rich stories revealed here for the first time.

A mathematical tour of some of the greatest unsolved ciphers of all time In 1953, a man was found dead from cyanide poisoning near the Philadelphia airport with a picture of a Nazi aircraft in his wallet. Taped to his abdomen was an enciphered message. In 1912, a book dealer named Wilfrid Voynich came into possession of an illuminated cipher manuscript once belonging to Emperor Rudolf II, who was obsessed with alchemy and the occult. Wartime codebreakers tried—and failed—to unlock the book's secrets, and it remains an enigma to this day. In this lively and entertaining book, Craig Bauer examines these and other vexing ciphers yet to be cracked. Some may reveal the identity of a spy or serial killer, provide the location of buried treasure, or expose a secret society—while others may be elaborate hoaxes. Unsolved! begins by explaining the basics of cryptology, and then explores the history behind an array of unsolved ciphers. It looks at ancient ciphers, ciphers created by artists and composers, ciphers left by killers and victims, Cold War ciphers, and many others. Some are infamous, like the ciphers in the Zodiac letters, while others were created purely as intellectual challenges by figures such as Nobel Prize–winning physicist Richard P. Feynman. Bauer lays out the evidence surrounding each cipher, describes the efforts of geniuses and eccentrics—in some cases both—to decipher it, and invites readers to try their hand at puzzles that have stymied so many others. Unsolved! takes readers from the ancient world to the digital age, providing an amazing tour of many of history's greatest unsolved ciphers.
