The award-winning New York Times bestseller about the American women who secretly served as codebreakers during World War II--a "prodigiously researched and engrossing" (New York Times) book that "shines a light on a hidden chapter of American history" (Denver Post). Recruited by the U.S. Army and Navy from small towns and elite colleges, more than ten thousand women served as codebreakers during World War II. While their brothers and boyfriends took up arms, these women moved to Washington and learned the meticulous work of code-breaking. Their efforts shortened the war, saved countless lives, and gave them access to careers previously denied to them. A strict vow of secrecy nearly erased their efforts from history; now, through dazzling research and interviews with surviving code girls, bestselling author Liza Mundy brings to life this riveting and vital story of American courage, service, and scientific accomplishment.

Decode the story of Elizebeth Friedman, the cryptologist who took down gangsters and Nazi spies In this picture book biography, young readers will learn all about Elizebeth Friedman (1892–1980), a brilliant American code breaker who smashed Nazi spy rings, took down gangsters, and created the CIA's first cryptology unit. Her story came to light when her secret papers were finally declassified in 2015. From thwarting notorious rumrunners with only paper and pencil to “counter-spying into the minds and activities of” Nazis, Elizebeth held a pivotal role in the early days of US cryptology. No code was too challenging for her to crack, and Elizebeth’s work undoubtedly saved thousands of lives. Extensive back matter includes explanations of codes and ciphers, further information on cryptology, a bibliography, a timeline of Elizebeth’s life, plus secret messages for young readers to decode.

"Along with a brief explanation of the workings of cipers and cryptanalysts, the computer program that accompanies this book provides a replacement for paper and pencil, which has always been a burdensome requirement in operating on ciphers. I think the tedium of a manual trial and error approach might tend to discourage a newcomer to the world of codes and ciphers. These computer programs take over that task and eliminate the tedium." -From foreword

For a long time, the Australian Signals intelligence (or Sigint) story has been kept secret. Until now… Why does Australia have a national signals intelligence agency? What does it do and why is it controversial? And how significant are its ties with key partners, the United States, the United Kingdom, Canada and New Zealand, to this arrangement? Revealing Secrets is a compelling account of Australian Signals intelligence, its efforts at revealing the secrets of other nations, and keeping ours safe. It brings to light those clever Australians whose efforts were for so long entirely unknown or overlooked. Blaxland and Birgin traverse the royal commissions and reviews that shaped Australia’s intelligence community in the 20th century and consider the advent and the impact of cyber. In unearthing this integral, if hidden and little understood, part of Australian statecraft, this book increases our understanding of the past, present and what lies ahead. ‘George Orwell famously wrote during World War Two, “we sleep safe in our beds because rough men stand ready in the night to visit violence on those who would do us harm”. Reading this superb history by John Blaxland and Clare Birgin on Australia’s involvement with Sigint and cyber we can contemplate a new formula. We sleep safer because 24/7 intelligent, technologically competent patriotic men and women who work for our agencies, develop and work our electronic defence and offence capacities at worldclass standard. This in a world now in which we are constantly under attack. The work so secret it is proving impossible to produce an official history. This is the closest we can get and it is very good. If you are seriously interested in our defence and survival, or you would just like a good read, this belongs on your bookshelf.’ — Kim Beazley, former Defence Minister ‘A meticulous compilation of the largely unsung past achievements of our most consistently productive intelligence source. And a thoughtful analysis of how to approach the extraordinary challenges posed by the new cyber universe. Blaxland and Birgin make an important contribution to our understanding of issues needing much more open debate than our own and allied governments have traditionally allowed or encouraged.’ — Gareth Evans, Former Australian Foreign Minister ‘Australia has been part of sigint since the practice began, which has shaped its history in ways that Australians know little about. Their government likes to keep things that way. Revealing Secrets overcomes efforts to keep Australians ignorant about their sigint history, by discussing everything that can be said about it without access to secret records. Anyone interested in the past and future of Australia has much to learn from this book.’ — John Ferris, author of Behind the Enigma, The Authorised History of GCHQ, Britain’s Secret Cyber Intelligence Agency ‘The most comprehensive and best-informed account we have had of the history of signals intelligence in Australia. Essential reading for anyone seeking to understand not just our country’s past, but Australia’s strategic future as well.’ — Allan Gyngell, author of Fear of Abandonment: Australia in the World Since 1942 ‘Revealing Secrets tell the remarkable but little-known story of how a small, back-room military office grew into a major Australian government agency. Deeply researched, authoritative and accessible, it is a valuable and timely contribution to understanding issues that have never been more important to national security.’ — Emeritus Professor David Horner, author of The Spy Catchers

The German military used the Geheimschreiber device to encode strategic communications. In 1940 Swedish mathematician Arne Beurling broke the code. Beckman (formerly the head of the cryptanalysis department of the Swedish signal intelligence agency) presents a narrative history of that achievement and other aspects of the Swedish code program that frequently strays into mathematical explanations of the cryptographic issues surrounding the story. Originally published in Swedish as Svenska kryptobedrifter. Annotation copyrighted by Book News, Inc., Portland, OR
