The magnificent, unrivaled history of codes and ciphers -- how they're made, how they're broken, and the many and fascinating roles they've played since the dawn of civilization in war, business, diplomacy, and espionage -- updated with a new chapter on computer cryptography and the Ultra secret. Man has created codes to keep secrets and has broken codes to learn those secrets since the time of the Pharaohs. For 4,000 years, fierce battles have been waged between codemakers and codebreakers, and the story of these battles is civilization's secret history, the hidden account of how wars were won and lost, diplomatic intrigues foiled, business secrets stolen, governments ruined, computers hacked. From the XYZ Affair to the Dreyfus Affair, from the Gallic War to the Persian Gulf, from Druidic runes and the kaballah to outer space, from the Zimmermann telegram to Enigma to the Manhattan Project, codebreaking has shaped the course of human events to an extent beyond any easy reckoning. Once a government monopoly, cryptology today touches everybody. It secures the Internet, keeps e-mail private, maintains the integrity of cash machine transactions, and scrambles TV signals on unpaid-for channels. David Kahn's The Codebreakers takes the measure of what codes and codebreaking have meant in human history in a single comprehensive account, astonishing in its scope and enthralling in its execution. Hailed upon first publication as a book likely to become the definitive work of its kind, The Codebreakers has more than lived up to that prediction: it remains unsurpassed. With a brilliant new chapter that makes use of previously classified documents to bring the book thoroughly up to date, and to explore the myriad ways computer codes and their hackers are changing all of our lives, The Codebreakers is the skeleton key to a thousand thrilling true stories of intrigue, mystery, and adventure. It is a masterpiece of the historian's art.

The mysterious connection between a teacher’s disappearance and an unsolved code in a children’s book is explored in this new novel from the “modern Agatha Christie” (The Sunday Times, London) and author of The Appeal. Forty years ago, Steven “Smithy” Smith found a copy of a famous children’s book by disgraced author Edith Twyford, its margins full of strange markings and annotations. When he showed it to his remedial English teacher Miss Iles, she believed that it was part of a secret code that ran through all of Twyford’s novels. And when she later disappeared on a class field trip, Smithy becomes convinced that she had been right. Now, out of prison after a long stretch, Smithy decides to investigate the mystery that has haunted him for decades. In a series of voice recordings on an old iPhone, Smithy alternates between visiting the people of his childhood and looking back on the events that later landed him in prison. But it soon becomes clear that Edith Twyford wasn’t just a writer of forgotten children’s stories. The Twyford Code holds a great secret, and Smithy may just have the key. “Filled with numerous clues, acrostics, and red herrings, this thrilling scavenger hunt for the truth is delightfully deceptive and thoroughly immersive” (Publishers Weekly, starred review).

Miss Amelia Bonnington has been in love with her childhood hero since she was eleven years old... or so she thought until a not-so proper impassioned and unyielding kiss from the not-so honorable and equally disreputable Lord Derrick Brinsley, gave her reason to question the feelings of the heart. Lord Brinsley, shunned from society for running off with his brother's fiancée, hasn't cared about or questioned his lack of acceptance until meeting the beguiling Amelia Bonnington.

To prove her French friend's innocence, she dangerously jumps into the fray, jeopardizing more than her life.

Information Security is usually achieved through a mix of technical, organizational and legal measures. These may include the application of cryptography, the hierarchical modeling of organizations in order to assure confidentiality, or the distribution of accountability and responsibility by law, among interested parties. The history of Information Security reaches back to ancient times and starts with the emergence of bureaucracy in administration and warfare. Some aspects, such as the interception of encrypted messages during World War II, have attracted huge attention, whereas other aspects have remained largely uncovered. There has never been any effort to write a comprehensive history. This is most unfortunate, because Information Security should be perceived as a set of communicating vessels, where technical innovations can make existing legal or organisational frame-works obsolete and a breakdown of political authority may cause an exclusive reliance on technical means.This book is intended as a first field-survey. It consists of twenty-eight contributions, written by experts in such diverse fields as computer science, law, or history and political science, dealing with episodes, organisations and technical developments that may considered to be exemplary or have played a key role in the development of this field.These include: the emergence of cryptology as a discipline during the Renaissance, the Black Chambers in 18th century Europe, the breaking of German military codes during World War II, the histories of the NSA and its Soviet counterparts and contemporary cryptology. Other subjects are: computer security standards, viruses and worms on the Internet, computer transparency and free software, computer crime, export regulations for encryption software and the privacy debate.- Interdisciplinary coverage of the history Information Security- Written by top experts in law, history, computer and information science- First comprehensive work in Information Security
