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.

The contributions reveal that, for the Axis as well as the Allies, success in the signals war often depended upon close collaboration among alliance partners.
Download or read book Democratizing Cryptography written by Rebecca Slayton and published by Morgan & Claypool. This book was released on 2022-08-25 with total page 558 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the mid-1970s, Whitfield Diffie and Martin Hellman invented public key cryptography, an innovation that ultimately changed the world. Today public key cryptography provides the primary basis for secure communication over the internet, enabling online work, socializing, shopping, government services, and much more. While other books have documented the development of public key cryptography, this is the first to provide a comprehensive insiders’ perspective on the full impacts of public key cryptography, including six original chapters by nine distinguished scholars. The book begins with an original joint biography of the lives and careers of Diffie and Hellman, highlighting parallels and intersections, and contextualizing their work. Subsequent chapters show how public key cryptography helped establish an open cryptography community and made lasting impacts on computer and network security, theoretical computer science, mathematics, public policy, and society. The volume includes particularly influential articles by Diffie and Hellman, as well as newly transcribed interviews and Turing Award Lectures by both Diffie and Hellman. The contributed chapters provide new insights that are accessible to a wide range of readers, from computer science students and computer security professionals, to historians of technology and members of the general public. The chapters can be readily integrated into undergraduate and graduate courses on a range of topics, including computer security, theoretical computer science and mathematics, the history of computing, and science and technology policy.

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.

This book was released on 2015-03-24 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Bulk Collection of Signals Intelligence: Technical Options study is a result of an activity called for in Presidential Policy Directive 28 (PPD-28), issued by President Obama in January 2014, to evaluate U.S. signals intelligence practices. The directive instructed the Office of the Director of National Intelligence (ODNI) to produce a report within one year "assessing the feasibility of creating software that would allow the intelligence community more easily to conduct targeted information acquisition rather than bulk collection." ODNI asked the National Research Council (NRC)-the operating arm of the National Academy of Sciences and National Academy of Engineering-to conduct a study, which began in June 2014, to assist in preparing a response to the President. Over the ensuing months, a committee of experts appointed by the Research Council produced the report.

Available in PDF, EPUB and Kindle. Book excerpt: “The expertly researched biography of the man who created and led the British intelligence organization best known for cracking the Nazi’s codes.” —Midwest Book Review Some of the individuals who played key roles in the success of Bletchley Park in reading the secret communications of Britain’s enemies during the Second World War have become well-known figures. However, the man who created and led the organization based there, from its inception in 1919 until 1942, has, surprisingly, been overlooked—until now. In 1914 Alastair Denniston, who had been teaching French and German at Osborne Royal Navy College, was one of the first recruits into the Admiralty’s fledgling codebreaking section that became known as Room 40. There, a team drawn from a wide range of professions successfully decrypted intercepted German communications throughout the First World War. After the Armistice, Room 40 was merged with the British Army’s equivalent section—MI1—to form the Government Code and Cypher School (GC&CS). Initially based in London, from August 1939, GC&CS was largely located at Bletchley Park, with Alastair Denniston as its Operational Director. With the support and assistance of both the Denniston family and GCHQ, Joel Greenberg, author of Gordon Welchman: Bletchley Park’s Architect of Ultra Intelligence, has produced this absorbing story of Commander Alexander “Alastair” Guthrie Denniston OBE, CBE, CMG, RNVR, a man whose death in 1961 was ignored by major newspapers and the very British intelligence organization that was his legacy. “An enthralling account of Alastair Denniston and his contribution to modern electronic intelligence. This book follows from his excellent biography of another great of signals intelligence, Gordon Welshman.” —Fire Reviews
