Download or read book Codes Ciphers and Spies written by John F. Dooley and published by Springer. This book was released on 2016-03-31 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: When the United States declared war on Germany in April 1917, it was woefully unprepared to wage a modern war. Whereas their European counterparts already had three years of experience in using code and cipher systems in the war, American cryptologists had to help in the building of a military intelligence unit from scratch. This book relates the personal experiences of one such character, providing a uniquely American perspective on the Great War. It is a story of spies, coded letters, plots to blow up ships and munitions plants, secret inks, arms smuggling, treason, and desperate battlefield messages. Yet it all begins with a college English professor and Chaucer scholar named John Mathews Manly. In 1927, John Manly wrote a series of articles on his service in the Code and Cipher Section (MI-8) of the U.S. Army’s Military Intelligence Division (MID) during World War I. Published here for the first time, enhanced with references and annotations for additional context, these articles form the basis of an exciting exploration of American military intelligence and counter-espionage in 1917-1918. Illustrating the thoughts of prisoners of war, draftees, German spies, and ordinary Americans with secrets to hide, the messages deciphered by Manly provide a fascinating insight into the state of mind of a nation at war.

Download or read book Unsolved written by Craig P. Bauer and published by Princeton University Press. This book was released on 2019-06-18 with total page 636 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In 1953, a man was found dead from cyanide poisoning near the Philadelphia airport with a picture of a Nazi aircraft in his wallet. Taped to his abdomen was an enciphered message. In 1912, a book dealer named Wilfrid Voynich came into possession of an illuminated cipher manuscript once belonging to Emperor Rudolf II, who was obsessed with alchemy and the occult. Wartime codebreakers tried--and failed--to unlock the book's secrets, and it remains an enigma to this day. In this lively and entertaining book, Craig Bauer examines these and other vexing ciphers yet to be cracked. Some may reveal the identity of a spy or serial killer, provide the location of buried treasure, or expose a secret society--while others may be elaborate hoaxes. Unsolved! begins by explaining the basics of cryptology, and then explores the history behind an array of unsolved ciphers. It looks at ancient ciphers, ciphers created by artists and composers, ciphers left by killers and victims, Cold War ciphers, and many others. Some are infamous, like the ciphers in the Zodiac letters, while others were created purely as intellectual challenges by figures such as Nobel Prize-winning physicist Richard P. Feynman. Bauer lays out the evidence surrounding each cipher, describes the efforts of geniuses and eccentrics--in some cases both--to decipher it, and invites readers to try their hand at puzzles that have stymied so many others. Unsolved! takes readers from the ancient world to the digital age, providing an amazing tour of many of history's greatest unsolved ciphers"--

Download or read book Venona written by John Earl Haynes and published by Yale University Press. This book was released on 1999-04-10 with total page 763 pages. Available in PDF, EPUB and Kindle. Book excerpt: This groundbreaking historical study reveals the shocking infiltration of Soviet spies in America—and the top-secret cryptography program that caught them. Only in 1995 did the United States government officially reveal the existence of the super-secret Venona Project. For nearly fifty years American intelligence agents had been decoding thousands of Soviet messages, uncovering an enormous range of espionage activities carried out against the United States during World War II by its own allies. This extraordinary book is the first to examine the Venona messages—documents of unparalleled importance for our understanding of the history and politics of the Stalin era and the early Cold War years. Hidden in a former girls’ school in the late 1940s, Venona Project cryptanalysts, linguists, and mathematicians attempted to decode thousands of intercepted Soviet intelligence telegrams. When they cracked the Soviet code, analysts uncovered information of powerful significance: the first indication of Julius Rosenberg’s espionage efforts; references to the espionage activities of Alger Hiss; proof of Soviet infiltration of the Manhattan Project; evidence that spies had reached the highest levels of the U.S. State and Treasury Departments; indications that more than three hundred Americans had assisted in the Soviet theft of American secrets; and confirmation that the Communist party of the United States was consciously and willingly involved in Soviet espionage against America. Drawing not only on the Venona papers but also on newly opened Russian and U. S. archives, John Earl Haynes and Harvey Klehr provide the most rigorously documented analysis ever written on Soviet espionage in the early Cold War years.
