 Protesters called it an act of war when the U.S. Coast Guard sank a Canadian-flagged vessel in the Gulf of Mexico in 1929. It took a cool-headed codebreaker solving a “trunk-full” of smugglers’ encrypted messages to get Uncle Sam out of the mess: Elizebeth Smith Friedman’s groundbreaking work helped prove the boat was owned by American gangsters. This book traces the career of a legendary U.S. law enforcement agent, from her work for the Allies during World War I through Prohibition, when she faced danger from mobsters while testifying in high profile trials. Friedman founded the cryptanalysis unit that provided evidence against American rum runners and Chinese drug smugglers. During World War II, her decryptions brought a Japanese spy to justice and her Coast Guard unit solved the Enigma ciphers of German spies. Friedman’s “all source intelligence” model is still used by law enforcement and counterterrorism agencies against 21st century threats.

This accessible textbook presents a fascinating review of cryptography and cryptanalysis across history. The text relates the earliest use of the monoalphabetic cipher in the ancient world, the development of the “unbreakable” Vigenère cipher, and an account of how cryptology entered the arsenal of military intelligence during the American Revolutionary War. Moving on to the American Civil War, the book explains how the Union solved the Vigenère ciphers used by the Confederates, before investigating the development of cipher machines throughout World War I and II. This is then followed by an exploration of cryptology in the computer age, from public-key cryptography and web security, to criminal cyber-attacks and cyber-warfare. Looking to the future, the role of cryptography in the Internet of Things is also discussed, along with the potential impact of quantum computing. Topics and features: presents a history of cryptology from ancient Rome to the present day, with a focus on cryptology in the 20th and 21st centuries; reviews the different types of cryptographic algorithms used to create secret messages, and the various methods for breaking such secret messages; provides engaging examples throughout the book illustrating the use of cryptographic algorithms in different historical periods; describes the notable contributions to cryptology of Herbert Yardley, William and Elizebeth Smith Friedman, Lester Hill, Agnes Meyer Driscoll, and Claude Shannon; concludes with a review of tantalizing unsolved mysteries in cryptology, such as the Voynich Manuscript, the Beale Ciphers, and the Kryptos sculpture. This engaging work is ideal as both a primary text for courses on the history of cryptology, and as a supplementary text for advanced undergraduate courses on computer security. No prior background in mathematics is assumed, beyond what would be encountered in an introductory course on discrete mathematics.

This book is part of the Army historical community's commemoration of the fiftieth anniversary of World War II. American victory in that conflict was brought about not only by the valor of our fighting men and the immensity of our productive capacity, but also by the availability of superb military intelligence. Much of this intelligence came from the ability of our armed forces to intercept and decipher the most secret communications of their adversaries. For many years security considerations prevented any public mention of these successes in the official histories. Now much of the story can be told. To preserve the memory of the Army's role in this intelligence war, the U. S. Army Center of Military History has joined with the History Office, U. S. Army Intelligence and Security Command (INSCOM), to publish this collection of documents on Army signals intelligence in World War II. INSCOM carries on the heritage of the Army's World War II Signal Security Agency, which by breaking the Japanese diplomatic ciphers and military codes helped speed the way of our forces to victory. The book is intended both for an Army audience and for the general public - including those World War II veterans who participated in the signals intelligence war and who for so many years were constrained to keep their contributions secret. The security barriers have now been lifted, and the Army is proud to acknowledge those contributions. Harold W. NelsonCharles F.

The book takes place in the poorest country in South America. In fact, in considering the Western Hemisphere, it ranks next to last, with only Haiti being poorer, yet it is a country rich in national resources. The book covers one of the most tenuous times in Bolivian history. While it is the story of a missionary family, the book provides unusual insight to the rapid change occurring at so many levels in the country. The book points to the 1952 revolution as the starting point of a vastly significant process of social and political transformation that has bought Bolivia to its present status. Bolivia has a history of political change occurring not at the ballot box but most frequently by a military coup. The ’52 revolution was like the jump start to a battery which, in this case, triggered the political awakening of the majority of indigenous communities long held in a semifeudal condition. The book draws out the many external influences which played a role in defining the outcome of the transition. Bolivia’s natural resources were a tempting prize from the early colonial period when gold and silver were the attractions for Spain. During World War II, the metals tin, zinc, and tungsten were important to the United States. More recently, for the time period covered by the book, it was the petroleum and forest products. The external influences were more than economic. The book covered the range from former Nazis to Cuban communists. The thread running through the book is about the life of a missionary family. It is the story of a young couple with three children who left the comfort and security of the US Midwest farming communities to serve Christ as missionaries to Bolivia. However, the book does much more. It reveals how these Americans adjust into what is a semi-hostile environment struggling to cast off its colonial past where 80 percent of the population was kept from participating in society by literacy voting laws. The book draws on sources as diverse as academic studies done as degree work by former missionaries, to declassed information from the State Department files. Events, both local and global, had their impact. Such political currents as those represented by Nazi Klaus Barbie and communist Che Guevara occurred in Bolivia. On the world scene, it ranged from Peron in Argentina to the assassination of President Kennedy in the U.S. While the book is about a missionary family, it so contextualizes them into the social, economic, and political situation in Bolivia, one comes away with a deeper appreciation for and understanding of those who dedicate their lives to the well-being of the world’s poorest and most marginalized.

The major guiding principle in the life of Tom Slick was a relentless search for adventure and exploration of the unknown, sparked by his immense curiosity about everything and his willingness to embrace and investigate new ideas. He was a larger-than-life Texas oilman, entrepreneur, and explorer. He climbed mountains in the Himalayas in search of the legendary Yeti. He developed new breeds of cattle. He discovered major oil fields. He founded several research institutes in San Antonio, including the Texas Biomedical Research Institute, Southwest Research Institute, and the Mind Science Foundation. He even wrote and published on the topic of world peace in the 1950s; the Tom Slick World Peace Lectures at the University of Texas’ LBJ Library and the endowed Tom Slick Professorship of World Peace were established after his death in 1962. In this revised and expanded edition of her previously published biography, Catherine Nixon Cooke, niece of Tom Slick, has mined personal letters, family papers, archives of the institutes founded by her uncle, and other resources to expand what we know of this enigmatic, energetic adventurer. In addition to relating his better-known exploits and pursuits, Cooke delves for the first time into Slick’s shadowy connections with the world of international espionage, including clues that Slick may have been involved in certain operations and interests of the OSS and its successor organization, the CIA. Illustrated throughout with rare historic photographs, In Search of Tom Slick: Explorer and Visionary will introduce a new readership to this influential yet little known figure in modern history.

The volume at hand, Dr. George F. Howe's American Signals Intelligence in Northwest Africa and Western Europe is important professional reading for those interested in cryptologic history or in World War II. Dr. Howe's book deals primarily with organizational matters for providing SIGINT support in combat. Thus, the reader will not find stories of high-level cryptanalysis underlying big decisions by famous leaders. In my estimation, by concentrating on the less flashy aspects of wartime support in favor of the background work, Dr. Howe has again added a dimension of great worth to our knowledge of SIGINT and of the war. The study of World War II SIGINT has concentrated, by and large, on ULTRA, the exploitation of high-grade cryptographic systems used by Germany and Japan, and the use of ULTRA material by senior wartime decision makers. This effort unquestionably is important for understanding the decisions and events of that terrible era, but the overwhelming focus on this aspect has resulted in a slightly skewed understanding. The production of ULTRA and its effective use depended on a strong and well-organized structure working in conjunction with now-legendary cryptanalysts. Since the distribution of ULTRA was limited to a small number of officers and civilian leaders, the bulk of SIGINT support to the warfighter cam from tactical SIGINT units working at or near the front lines. This is an important subject for understanding what happened in World War II and for studying the principles of SIGINT organization today.
