Book Description
United States Diplomatic Codes and Ciphers, 1775-1938 is the first basic reference work on American diplomatic cryptography. Weber's research in national and private archives in the Americas and Europe has uncovered more than one hundred codes and ciphers. Beginning with the American Revolution, these secret systems masked confidential diplomatic correspondence and reports.During the period between 1775 and 1938, both codes and ciphers were employed. Ciphers were frequently used for American diplomatic and military correspondence during the American Revolution. At that time, a system was popular among American statesmen whereby a common book, such as a specific dictionary,was used by two correspondents who encoded each word in a message with three numbers. In this system, the first number indicated the page of the book, the second the line in the book, and the third the position of the plain text word on that line counting from the left. Codes provided the most common secret language basis for the entire nineteenth century.Ralph Weber describes in eight chapters the development of American cryptographic practice. The codes and ciphers published in the text and appendix will enable historians and others to read secret State Department dispatches before 1876, and explain code designs after that year.

Book Description
At Home in the Netherlands uses a range of indicators to describe developments in the integration of non-Western migrants and their children in the Netherlands. Attention is focused on the situation of non-Western children in education, the position of non-Western migrants on the labour and housing markets, their representation in the crime figures and their degree of socio-cultural integration. The book also looks at civic integration, the mutual perceptions of the non-Western and indigenous populations, and the life situation of young people with a non-Western background.

Book Description
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.

Book Description
One of the most colorful and controversial figures in American intelligence, Herbert O. Yardley (1889-1958) gave America its best form of information, but his fame rests more on his indiscretions than on his achievements. In this highly readable biography, a premier historian of military intelligence tells Yardley's story and evaluates his impact on the American intelligence community. Yardley established the nation's first codebreaking agency in 1917, and his solutions helped the United States win a major diplomatic victory at the 1921 disarmament conference. But when his unit was closed in 1929 because "gentlemen do not read each other's mail," Yardley wrote a best-selling memoir that introduced-and disclosed-codemaking and codebreaking to the public. David Kahn de-scribes the vicissitudes of Yardley's career, including his work in China and Canada, offers a capsule history of American intelligence up to World War I, and gives a short course in classical codes and ciphers. He debunks the accusations that the publication of Yardley's book caused Japan to change its codes and ciphers and that Yardley traitorously sold his solutions to Japan. And he asserts that Yardley's disclosures not only did not hurt but actually helped American codebreaking during World War II.

Book Description
This volume opens on 4 March 1802, the first anniversary of Thomas Jefferson's inauguration as the nation's third president, and closes on 30 June. In March, a delegation of Seneca Indians comes to Washington to discuss their tribe's concerns, and Jefferson names a commissioner to handle a land sale by Oneida Indians to the state of New York. In April, the Senate ratifies a treaty with the Choctaw nation for a wagon road across their lands. Jefferson worries about an increasingly dictatorial France taking back control of New Orleans, prompting him to the intemperate remark that he would "marry" America's fortunes to the British fleet. Charles Willson Peale sends him sketches of the skull of a prehistoric bison found in Kentucky. During the closing, and very frustrating, weeks of Congress, he distracts himself with a cipher devised by Robert Patterson. He prepares lists of books to be purchased for the recently established Library of Congress and also obtains many titles for his own collection. Even while he is in Washington occupied with matters of state, Jefferson has been keeping close watch on the renovations at Monticello. In May, he has Antonio Giannini plant several varieties of grapes in the southwest vineyard, and he orders groceries, molasses, dry Lisbon wine, and cider to be shipped to Monticello in time for his arrival. He looks forward "with impatience" to the moment he can embrace his family once more.
