The Code Book: The Secret History of Codes and Code-breaking

Product Information

Book ciphers have been used frequently both for real secrecy as well as in popular culture for entertainment. Friedman, were the subjects of a short article in TIME magazine about their new book debunking a long-held theory that William Shakespeare wasn’t the true author of his plays, and that a cipher was hidden within his texts pointing to the “real” author’s identity. Edgar Hoover, who claimed that the FBI had led the code-breaking effort and thus erased the contribution of Friedman and her team.

Codebreaking by Elonka Dunin | Hachette UK

This isn’t just a book about cryptography and cryptanalysis, it’s a fascinating glimpse into humankind’s use of secrecy and deception to serve a variety of interests. An easy experiment you can do to test this out is to get everyone in your class to raise their hand if they have the letter 'E' in their name. The big problem with military codebreaking is using the operational intelligence obtained by breaking codes without revealing to the enemy that his codes have been broken. If you’re looking for a source book to learn the art and science of cracking codes, it’s hard to find a better collection than the deep and well-documented collection in this book. Friedman signed a Navy oath promising her silence until her death, which was in 1980, and stayed true to it for all those decades.I have been a creator and solver of puzzles both virtual and physical my whole life, I even gave my wife a GPS-enabled puzzle box as a wedding present to lead her to our honeymoon.

But in 1992, the US Justice Department claimed releasing the third book could harm national security by revealing the NSA's " code-breaking prowess". The code-breaker considers the weight of evidence and guesses the likely cause of an observed effect. One of them contained 3,500 vacuum tubes; for comparison, ENIAC, the first semi-modern computer, contained 17,000 vacuum tubes. Covers the Bletchley Park story and breaking Enigma, and fixes some previously incorrect beliefs of the general public. The story behind a code is often as important and compelling as the code itself, and Dunin and Schmeh never fail to deliver with each one they examine.It's packed full of information about all sorts of codes, including the famous story Enigma, the code machine used by the Germans during WWII. Also recommended for readers of Sayers' _Have His Carcase_ who want to understand more than the Playfair explanation there.

The Code Book: The Secret History of Codes and Code-breaking

Dunin and Schmeh, two internationally known experts on cryptology, show you step by step how to crack codes and ciphers from before the earliest radio transmissions to the world of contemporary computing. The creator of such a puzzle, she said, "fails to submit material in proportion to the amount of complication he has introduced.With its lovely codebreaking demonstrations, this book is a real starting manual for any crypto novice. While the details and descriptions of the actual machines and sometimes the code breaking process were a little difficult to plow through at times, I found the human stories fascinating. Similarly, US artist Jim Sanborn's famous Kryptos sculpture, located at the Central Intelligence Agency, has long confounded attempts to unlock its code. This masterpiece is both an extension as well as a successor of the existing and nowadays partially outdated works about (unsolved) codes and cryptography – from Helen F.
