Cryptologic Aspects Of German Intelligence Activities In South America During World War Ii

This publication joins two cryptologic history monographs that were published separately in 1989. In part I, the author identifies and presents a thorough account of German intelligence organizations engaged in clandestine work in South America as well as a detailed report of the U.S. response to the perceived threat. Part II deals with the cryptographic systems used by the varioius German intelligence organizations engaged in clandestine activities.

 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.

En beskrivelse af tysk spionage og efterretningsvirksomhed i Sydamerika under 2. Verdenskrig og de allieredes modforholdsregler. Især Brasilien spillede en væsentlig rolle p.gr.a tætte relationer til Tyskland og landets beliggenhed i forhold til de allieredes konvojruter

Et omfattende studie af tysk efterretningstjeneste og spionage i Latinamerika i 1930erne og 40erne samt USAs kontraspionage.

Drawing heavily on recently declassified sources, this examination of German wartime intelligence services traces the logistical and strategic expansion of the Third Reich's foreign covert operations in World War II. Beginning with the changes introduced to counteract institutional neglect, the author describes attempts to penetrate both neutral and adversarial nations outside territories occupied by the Wehrmacht. The Nazis created covert teams for counterintelligence and penetrating border defenses. Strategies were formed for assembling saboteur divisions in North and South America, while data were gathered on industrial installations to target. American fascist movements of the 1930s are discussed, along with Nazi sabotage missions in the United States and intelligence penetrations and domestic collusion in Latin America.

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.

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.

"Though officially neutral until March 1945, Buenos Aires played a key role during World War II as a base for the South American intelligence operations of the major powers. The Hidden War in Argentina reveals the stories of the spymasters, British, Americans and Germans who plotted against each other throughout the Second World War in Argentina. In Buenos Aires, Johannes Siegfried Becker - codename 'Sargo' ?́" was the man responsible for organizing most of the Nazi intelligence gathering in Latin America and the leader of 'Operation Bolivar', which sought to bring South America into the war on the side of the Axis powers. After the attack on Pearl Harbor the US state department pressured every South American country to join it in declaring war on Germany, and J Edgar Hoover authorized huge investments in South American intelligence operations. Argentina continued to refuse to join the conflict, triggering a US embargo that squeezed the country's economy to breaking point. Buenos Aires continued to be a hub for espionage even as the war in Europe was ending ?́" hundreds of high-ranking Nazi exiles sought refuge there. This book is based on newly declassified files and details of the operations of MI6, the Abwehr, the Sicherheitsdienst (SD) and the FBI, as well as the OSS and the SOE. Most significantly, The Hidden War in Argentina reveals for the first time the coups of Britain's MI6 in South America."--
