Codes and Ciphers: Julius Caesar, the Enigma, and the Internet

Great reference book. It'll take it's place on my 'Code Book' shelf.

It's a good book if you have an interest in ciphers and haven't read much on the subject. It's not a book on modern cryptography and covers very little in the way of recent breakthrough technology. Based on your level of interest and experience it might or might not be the right book for you. It gets four stars from me because the author presents clear, well researched information.

This is not a schoolbook, yet it takes from the format some usefull features for such a book : you have some worked out examples and a few exercises to practice. After all, math is not something you read like a novel, but rather something you DO! The author understands that.But the book also has an easy going feel to it and is very clear. Mixed in with the math, you have tidbits of history and general culture mixed in. If you compare it to a very good book out there (the code book by Singh), you find out more about the codes and the mechanics of them in this book.good read!

授業で必要なので購入しました。古い本なのでISBNなど今と少し異なりますが内容的にはあまり難しくはないと思います。ただ私は英語が苦手なので読むのに苦戦しています。
