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.

View: 7619

The Mathematics of Secrets takes readers on a fascinating tour of the mathematics behind cryptography—the science of sending secret messages. Most books about cryptography are organized historically, or around how codes and ciphers have been used, such as in government and military intelligence or bank transactions. Joshua Holden instead shows how mathematical principles underpin the ways that different codes and ciphers operate. Holden focuses on both code making and code breaking and he discusses the majority of ancient and modern ciphers currently known. Holden begins by looking at substitution ciphers, built by substituting one letter or block of letters for another. Explaining one of the simplest and historically well-known ciphers, the Caesar cipher, Holden establishes the key mathematical idea behind the cipher and discusses how to introduce flexibility and additional notation. Holden goes on to explore polyalphabetic substitution ciphers, transposition ciphers, including one developed by the Spartans, connections between ciphers and computer encryption, stream ciphers, and ciphers involving exponentiation. He also examines public-key ciphers, where the methods used to encrypt messages are public knowledge, and yet, intended recipients are still the only ones who are able to read the message. He concludes with a look at the future of ciphers and where cryptography might be headed. Only basic mathematics up to high school algebra is needed to understand and enjoy the book. With a plethora of historical anecdotes and real-world examples, The Mathematics of Secrets reveals the mathematics working stealthily in the science of coded messages.

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.

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.

NATIONAL BESTSELLER NPR Best Book of 2017 “Not all superheroes wear capes, and Elizebeth Smith Friedman should be the subject of a future Wonder Woman movie.” — The New York Times Joining the ranks of Hidden Figures and In the Garden of Beasts, the incredible true story of the greatest codebreaking duo that ever lived, an American woman and her husband who invented the modern science of cryptology together and used it to confront the evils of their time, solving puzzles that unmasked Nazi spies and helped win World War II. In 1916, at the height of World War I, brilliant Shakespeare expert Elizebeth Smith went to work for an eccentric tycoon on his estate outside Chicago. The tycoon had close ties to the U.S. government, and he soon asked Elizebeth to apply her language skills to an exciting new venture: code-breaking. There she met the man who would become her husband, groundbreaking cryptologist William Friedman. Though she and Friedman are in many ways the "Adam and Eve" of the NSA, Elizebeth’s story, incredibly, has never been told. In The Woman Who Smashed Codes, Jason Fagone chronicles the life of this extraordinary woman, who played an integral role in our nation’s history for forty years. After World War I, Smith used her talents to catch gangsters and smugglers during Prohibition, then accepted a covert mission to discover and expose Nazi spy rings that were spreading like wildfire across South America, advancing ever closer to the United States. As World War II raged, Elizebeth fought a highly classified battle of wits against Hitler’s Reich, cracking multiple versions of the Enigma machine used by German spies. Meanwhile, inside an Army vault in Washington, William worked furiously to break Purple, the Japanese version of Enigma—and eventually succeeded, at a terrible cost to his personal life. Fagone unveils America’s code-breaking history through the prism of Smith’s life, bringing into focus the unforgettable events and colorful personalities that would help shape modern intelligence. Blending the lively pace and compelling detail that are the hallmarks of Erik Larson’s bestsellers with the atmosphere and intensity of The Imitation Game, The Woman Who Smashed Codes is page-turning popular history at its finest.

For almost four desperate years, from 1939 to mid-1943, the British and American navies fought a savage, losing battle against German submarine wolfpacks. The Allies might never have turned the tide without an intelligence coup. The race to break the German U-boat codes is one of the greatest untold stories of World War II. Kahn expertly brings this tale to life in this newly-updated edition of his classic book. Soon after war broke out, HitlerÕs U-boats began to sever Allied lifelines. In the gray wasteland of the North Atlantic, submarines prowled; at night, the sky lit up with the flames of exploding tankers. To meet the growing crisis, ingenious amateurs joined the nucleus of dedicated professionals at Bletchley Park. As the Battle of the Atlantic raged, they raced to unlock the continually changing German naval codes. Their mission: to read the U-boat messages of HitlerÕs cipher device, the Enigma. Critical to their success was a series of raids at sea. U-110, captured intact in the mid-Atlantic, yielded the Enigma machine itself and also a trove of secret documents. The weather ship Lauenburg seized near the Arctic ice pack provided codesettings for an entire month. In the Mediterranean, two sailors rescued a German weather cipher than enabled the team at Bletchley to solve the Enigma after a year-long blackout.

In this gripping, previously untold story from World War II, Michael Smith examines how code breakers cracked Japan’s secret codes and won the war in the Pacific. He also takes the reader step by step through the process, explaining exactly how the code breakers went about their daunting task—made even more difficult by the vast linguistic differences between Japanese and English. The Emperor’s Codes moves across the world from Bletchley Park to Pearl Harbor, from Singapore to Colombo, and from Mombasa to Melbourne. It tells the stories of John Tiltman, the British soldier turned code breaker who made many of the early breaks in Japanese diplomatic and military codes; Commander Joe Rochedort, the leading expert on Japanese in U.S. naval intelligence; Eric Nave, the Australian sailor who pioneered breakthroughs in deciphering Japanese naval codes; and Oshima Hiroshi, the hard-drinking Japanese ambassador to Berlin whose candid, often verbose reports to Tokyo of his conversations with Hitler and other high-ranking Nazis were a major source of intelligence in the war against Germany. Without the dedication demonstrated by these relatively unsung heroes, the outcome of World War II might have been very different.

Winner of an Outstanding Academic Title Award from CHOICE Magazine Most available cryptology books primarily focus on either mathematics or history. Breaking this mold, Secret History: The Story of Cryptology gives a thorough yet accessible treatment of both the mathematics and history of cryptology. Requiring minimal mathematical prerequisites, the book presents the mathematics in sufficient detail and weaves the history throughout the chapters. In addition to the fascinating historical and political sides of cryptology, the author—a former Scholar-in-Residence at the U.S. National Security Agency (NSA) Center for Cryptologic History—includes interesting instances of codes and ciphers in crime, literature, music, and art. Following a mainly chronological development of concepts, the book focuses on classical cryptology in the first part. It covers Greek and Viking cryptography, the Vigenère cipher, the one-time pad, transposition ciphers, Jefferson’s cipher wheel, the Playfair cipher, ADFGX, matrix encryption, World War II cipher systems (including a detailed examination of Enigma), and many other classical methods introduced before World War II. The second part of the book examines modern cryptology. The author looks at the work of Claude Shannon and the origin and current status of the NSA, including some of its Suite B algorithms such as elliptic curve cryptography and the Advanced Encryption Standard. He also details the controversy that surrounded the Data Encryption Standard and the early years of public key cryptography. The book not only provides the how-to of the Diffie-Hellman key exchange and RSA algorithm, but also covers many attacks on the latter. Additionally, it discusses Elgamal, digital signatures, PGP, and stream ciphers and explores future directions such as quantum cryptography and DNA computing. With numerous real-world examples and extensive references, this book skillfully balances the historical aspects of cryptology with its mathematical details. It provides readers with a sound foundation in this dynamic field.
