Description
by Craig P. Bauer (Author)
A mathematical tour of some of the greatest unsolved ciphers of all time
In 1953, a man was found dead from cyanide poisoning near the Philadelphia airport with a picture of a Nazi aircraft in his wallet and an enciphered message taped to his abdomen. 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. He lays out the evidence surrounding each cipher, describes the efforts to decipher it, and invites readers to try their hand at puzzles that have stymied so many others.Back Jacket
"Exceptional. Not only are these ciphers fascinating individually, but together they provide a comprehensive picture of the different methods and types of encryption, which Bauer explains and guides readers through in turn. I thoroughly enjoyed this book."--Todd S. Sauter, National Cryptologic Museum
"A great book and a major contribution."--Klaus Schmeh, author of Cryptography and Public Key Infrastructure on the Internet
"A welcome addition to the growing popular literature on cryptology. Bauer explains concepts very clearly and illustrates them with examples, so that the book is self-contained and requires little prerequisite mathematical or cryptological background knowledge on the part of the reader."--John W. Dawson, Jr., author of Logical Dilemmas: The Life and Work of Kurt Godel
