Available in PDF, EPUB and Kindle. Book excerpt: Despite publicity given to the successes of British and American codebreakers during the Second World War, the study of signals intelligence is still complicated by governmental secrecy over even the most elderly peacetime sigint. This book, first published in 1986, lifts the veil on some of these historical secrets. Christopher Andrew and Keith Neilson cast new light on how Tsarist codebreakers penetrated British code and cypher systems. John Chapman’s study of German military codebreaking represents a major advance in our understanding of cryptanalysis during the Weimar Republic. The history of the Government Code and Cypher School – forerunner of today’s GCHQ – by its operational head, the late A.G. Denniston, provides both a general assessment of the achievements of British cryptanalysis between the wars and a tantalising glimpse of what historians may one day find in GCHQ’s forbidden archives. The distinguished cryptanalyst of Bletchley Park, the late Gordon Welchman, describes in detail how the Ultra programme defeated the German Enigma machine, while another Bletchley Park cryptographer, Christopher Morris, reminds us in his account of the valuable work on hand cyphers that wartime sigint consisted of much more than Ultra. Roger Austin’s study of surveillance under the Vichy regime shows the continuing importance of older and simpler methods of message interception such as letter-opening. Taken together, the articles establish sigint as an essential field of study for both the modern historian and the political scientist.

Download or read book Code Warriors written by Stephen Budiansky and published by Knopf. This book was released on 2016 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Bletchley Park and D Day written by David Kenyon and published by Yale University Press. This book was released on 2019-07-16 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: The untold story of Bletchley Park's key role in the success of the Normandy campaign Since the secret of Bletchley Park was revealed in the 1970s, the work of its codebreakers has become one of the most famous stories of the Second World War. But cracking the Nazis' codes was only the start of the process. Thousands of secret intelligence workers were then involved in making crucial information available to the Allied leaders and commanders who desperately needed it. Using previously classified documents, David Kenyon casts the work of Bletchley Park in a new light, as not just a codebreaking establishment, but as a fully developed intelligence agency. He shows how preparations for the war's turning point--the Normandy Landings in 1944--had started at Bletchley years earlier, in 1942, with the careful collation of information extracted from enemy signals traffic. This account reveals the true character of Bletchley's vital contribution to success in Normandy, and ultimately, Allied victory.
Download or read book Hitler s Codebreakers written by John Jackson and published by Booktowerpublishing. This book was released on 2013-04-25 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Have you ever wondered how successful Hitler's codebreakers were at breaking Allied codes during World War 2? The wartime story of codebreaking has almost exclusively centred around Allied successes, particularly that of Bletchley Park breaking the Enigma code. However, the Germans in particular were extremely active in codebreaking and had their successes. But it was not until after the war that the extent or otherwise of their triumphs could be gauged. With the war in Europe at an end, in April-May 1945 British and American codebreaking teams hunted for their German counterparts to find out just how good they had been. There were lessons to be learned for the post-war period for Western military intelligence. This publication is a summary of the European Axis Signal Intelligence in World War II as revealed by 'TICOM' Investigations and by other Prisoner of War Interrogations and Captured Material, Principally German and completed in May 1946. This is available on the National Security Agency website. TICOM - Target Intelligence Committee - was a shadowy Anglo-American organisation set up in October 1944 whose cover name disguised its real purpose - the seeking out in the immediate aftermath of the war of German Sigint staff for interrogation. This edited volume extracts key data from the 1000 pages of the original documents to create a fascinating and technical insight into German cryptography. The book is a technical summary of the TICOM documents using the words of those who collected the data. The complex data was written for military analysis so the Allies could assess Hitler's codebreaking operation during the war. It becomes clear that Hitler's team understood that the Enigma cipher machine had weaknesses and that they had various ingenious machines either developed or under development as the war drew to a close. Lack of resources - and running out of time - put paid to any major operational deployment of this machinery, but underlines the fact that German ingenuity came close to a situation where they would have made Bletchley Park's task almost impossible. Includes a report on the interrogation of 5 leading Germans in Nuremburg, September 1945 regarding signals intelligence. They are: General Jodl, Grand Admiral Donitz, General Field Marshall Keitel, Herr von Ribbentrop and Field Marshall Goering.
Download or read book Secrets of Signals Intelligence During the Cold War and Beyond written by Matthew M. Aid and published by Psychology Press. This book was released on 2001 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years the importance of Signals Intelligence (Sigint) has become more prominent, especially the capabilities and possibilities of reading and deciphering diplomatic, military and commercial communications of other nations. This growing awareness of the importance of intelligence applies not only to the activities of the big services but also to those smaller nations like The Netherlands. For this reason The Netherlands Intelligence Association (NISA) was recently established in which academics and (former and still active) members of The Netherlands intelligence community work together in order to promote research into the history of Dutch intelligence communities.--
Download or read book Secret Messages written by David J. Alvarez and published by . This book was released on 2000 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: To defeat your enemies you must know them well. In wartime, however, enemy codemakers make that task much more difficult. If you cannot break their codes and read their messages, you may discover too late the enemy's intentions. That's why codebreakers were considered such a crucial weapon during World War II. In Secret Messages, David Alvarez provides the first comprehensive analysis of the impact of decoded radio messages (signals intelligence) upon American foreign policy and strategy from 1930 to 1945. He presents the most complete account to date of the U.S. Army's top-secret Signal Intelligence Service (SIS): its creation, its struggles, its rapid wartime growth, and its contributions to the war effort. Alvarez reveals the inner workings of the SIS (precursor of today's NSA) and the codebreaking process and explains how SIS intercepted, deciphered, and analyzed encoded messages. From its headquarters at Arlington Hall outside Washington, D.C., SIS grew from a staff of four novice codebreakers to more than 10,000 people stationed around the globe, secretly monitoring the communications of not only the Axis powers but dozens of other governments as well and producing a flood of intelligence. Some of the SIS programs were so clandestine that even the White House—unaware of the agency's existence until 1937—was kept uninformed of them, such as the 1943 creation of a super-secret program to break Soviet codes and ciphers. In addition, Alvarez brings to light such previously classified operations as the interception of Vatican communications and a comprehensive program to decrypt the communications of our wartime allies. He also dispels many of the myths about the SIS's influence on American foreign policy, showing that the impact of special intelligence in the diplomatic sphere was limited by the indifference of the White House, constraints within the program itself, and rivalries with other agencies (like the FBI). Drawing upon military and intelligence archives, interviews with retired and active cryptanalysts, and over a million pages of cryptologic documents declassified in 1996, Alvarez illuminates this dark corner of intelligence history and expands our understanding of its role in and contributions to the American effort in World War II.
Download or read book The Secret Code Breakers of Central Bureau written by David Dufty and published by . This book was released on 2023-02-28 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Central Bureau - Australia's own large and sophisticated intelligence network, built from scratch. It was this group of mathematicians, code-breakers, and radio experts who intercepted the travel plans of the architect of the Pearl Harbor attack, Admiral Yamamoto, leading to his ambush and death. Australian signals intelligence also played a vital role in the battles of the Coral Sea, Milne Bay, Hollandia, and many others. General Douglas MacArthur, the supreme commander of the local Allied forces, went so far as to insist that the men of Central Bureau accompany him on his counter-attack in the Pacific. After the war, the US sought to give these non-combatants the highest awards possible - honours that were suppressed by the Australian government in their need for secrecy. A groundbreaking work of military history, The Secret Code-breakers of Central Bureau gives these talented and dedicated individuals their due at last. It is a rich account of the shadowy side of military strength and of the men and women whose work was, in the words of the US navy, of 'immeasurable importance in the successfulmprosecution' of the Pacific War. 'Who knew? This enthralling study tells a deeply human story. The men and women who gave our troops a significant edge in the fight against the Japanese are the genuine heroes in this engaging and exciting book.' -Michael McKernan, author of The Strength of a Nation and When This Thing Happened 'This is history and military strategy written at its most engaging.' -Waikato Times 'A delightfully and thoroughly engaging story of the emergence of the Australian contribution to the signals and radio interception intelligence ... Dufty's writing style is light and easy to read, reminiscent of other contemporary historical narratives that tell a series of stories, most notably the emphasis of the human story associated with these experiences.' -Rhys Ball, NZ International Review

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: 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.

Book excerpt: 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.
