In 1974 Frederick W. Winterbotham's book The Ultra Secret disclosed the Allied success in breaking the German high command ciphers in World War II, and a new form of history began—the study of intelligence and its impact on military operations and international politics. This guide documents and annotates over 800 sources that have appeared in the past 20 years. It examines and evaluates primary and secondary sources dealing with the role of ULTRA and MAGIC in the Pearl Harbor attack, the battles of the Atlantic, Coral Sea, and Midway, and the campaigns in the Mediterranean, Northwest Europe, the Middle East, and the Pacific, as well as in the realm of espionage and special operations. It also covers sources on the Sigint and cryptanalytic programs of the Axis and neutral powers.

Here is the ultimate inside history of twentieth-century intelligence gathering and covert activity. Unrivalled in its scope and as readable as any spy novel, A Century of Spies travels from tsarist Russia and the earliest days of the British Secret Service to the crises and uncertainties of today's post-Cold War world, offering an unsurpassed overview of the role of modern intelligence in every part of the globe. From spies and secret agents to the latest high-tech wizardry in signals and imagery surveillance, it provides fascinating, in-depth coverage of important operations of United States, British, Russian, Israeli, Chinese, German, and French intelligence services, and much more. All the key elements of modern intelligence activity are here. An expert whose books have received high marks from the intelligence and military communities, Jeffrey Richelson covers the crucial role of spy technology from the days of Marconi and the Wright Brothers to today's dazzling array of Space Age satellites, aircraft, and ground stations. He provides vivid portraits of spymasters, spies, and defectors--including Sidney Reilly, Herbert Yardley, Kim Philby, James Angleton, Markus Wolf, Reinhard Gehlen, Vitaly Yurchenko, Jonathan Pollard, and many others. Richelson paints a colorful portrait of World War I's spies and sabateurs, and illuminates the secret maneuvering that helped determine the outcome of the war on land, at sea, and on the diplomatic front; he investigates the enormous importance of intelligence operations in both the European and Pacific theaters in World War II, from the work of Allied and Nazi agents to the "black magic" of U.S. and British code breakers; and he gives us a complete overview of intelligence during the length of the Cold War, from superpower espionage and spy scandals to covert action and secret wars. A final chapter probes the still-evolving role of intelligence work in the new world of disorder and ethnic conflict, from the high-tech wonders of the Gulf War to the surprising involvement of the French government in industrial espionage. Comprehensive, authoritative, and addictively readable, A Century of Spies is filled with new information on a variety of subjects--from the activities of the American Black Chamber in the 1920s to intelligence collection during the Cuban missile crisis to Soviet intelligence and covert action operations. It is an essential volume for anyone interested in military history, espionage and adventure, and world affairs.

This Festschrift volume is published in honor of David Kahn and is the outcome of a Fest held in Luxembourg in 2010 on the occasion of David Kahn’s 80th birthday. The title of this books leans on the title of a serious history of cryptology named “The Codebreakers”, written by David Kahn and published in 1967. This book contains 35 talks dealing with cryptography as a whole. They are organized in topical section named: history; technology – past, present, future; efficient cryptographic implementations; treachery and perfidy; information security; cryptanalysis; side-channel attacks; randomness embedded system security; public-key cryptography; and models and protocols.

"The cumulative effect is overwhelming. Eleanor Roosevelt was right: Hoover’s FBI was an American gestapo." —Newsweek Shocking, grim, frightening, Curt Gentry’s masterful portrait of America’s top policeman is a unique political biography. From more than 300 interviews and over 100,000 pages of previously classified documents, Gentry reveals exactly how a paranoid director created the fraudulent myth of an invincible, incorruptible FBI. For almost fifty years, Hoover held virtually unchecked public power, manipulating every president from Franklin D. Roosevelt to Richard Nixon. He kept extensive blackmail files and used illegal wiretaps and hidden microphones to destroy anyone who opposed him. The book reveals how Hoover helped create McCarthyism, blackmailed the Kennedy brothers, and influenced the Supreme Court; how he retarded the civil rights movement and forged connections with mobsters; as well as insight into the Watergate scandal and what part he played in the investigations of President John F. Kennedy and Martin Luther King Jr.

Explaining the mathematics of cryptography The Mathematics of Secrets takes readers on a fascinating tour of the mathematics behind cryptography—the science of sending secret messages. Using a wide range of historical anecdotes and real-world examples, Joshua Holden shows how mathematical principles underpin the ways that different codes and ciphers work. He focuses on both code making and code breaking and discusses most of the ancient and modern ciphers that are currently known. He begins by looking at substitution ciphers, and then discusses how to introduce flexibility and additional notation. Holden goes on to explore polyalphabetic substitution ciphers, transposition ciphers, connections between ciphers and computer encryption, stream ciphers, public-key ciphers, and ciphers involving exponentiation. He concludes by looking at the future of ciphers and where cryptography might be headed. The Mathematics of Secrets reveals the mathematics working stealthily in the science of coded messages.
