This book reveals the historical context and the evolution of the technically complex Allied Signals Intelligence (Sigint) activity against Japan from 1920 to 1945. It traces the all-important genesis and development of the cryptanalytic techniques used to break the main Japanese Navy code (JN-25) and the Japanese Army’s Water Transport Code during WWII. This is the first book to describe, explain and analyze the code breaking techniques developed and used to provide this intelligence, thus closing the sole remaining gap in the published accounts of the Pacific War. The authors also explore the organization of cryptographic teams and issues of security, censorship, and leaks. Correcting gaps in previous research, this book illustrates how Sigint remained crucial to Allied planning throughout the war. It helped direct the advance to the Philippines from New Guinea, the sea battles and the submarine onslaught on merchant shipping. Written by well-known authorities on the history of cryptography and mathematics, Code Breaking in the Pacific is designed for cryptologists, mathematicians and researchers working in communications security. Advanced-level students interested in cryptology, the history of the Pacific War, mathematics or the history of computing will also find this book a valuable resource.

On his 81st birthday, without explanation, Karen Fisher-Alaniz's father placed two weathered notebooks on her lap. Inside were more than 400 pages of letters he'd written to his parents during WWII. She began reading them, and the more she read, the more she discovered about the man she never knew. They began to meet for lunch every week, for her to ask him questions, and him to provide the answers. It was through this process that she discovered the secret role he played in WWII. Karen's father was part of a small and elite group of men who were trained to copy and break top-secret Japanese code transmitted in Katakana. Through this journey, with painful memories now at the forefront of his thoughts, Karen's father began to suffer, making their meetings as much about healing as discovery. Thus began an unintended journey-one taken by a father and daughter who thought they knew each other-as they became newly bound in ways that transcended age and time.

'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

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.
