OK, this book has received prizes and stellar reviews here and elsewhere but personally I didn't like it very much. First, the text and the exercises lack mathematical depth. There are entire chapters, such as the one on AES, which add hardly anything to the official standard, and the book explanation is often harder to understand, and especially more ambiguous than the official standard of the protocols it is supposed to explain.

On the other hand, it is a relatively "polished" book, without too many errors or typos. Most of the time, it gives gives enough information to implement the algorithms it talks about. But it certainly doesn't give you enough to become a cryptographer, or to evaluate the security of a new algorithm, or things like that.

There has never been a more poorly written book, to my knowledge. The subject matter is fascinating and it is hard to imagine a less well-executed explanation of this material. It is difficult to count how many times that concepts are introduced and explained with statements that begin "It is obvious that..." - I've got news for the author, not much of those things are obvious, and smaller books explain the same material in much clearer and accessible language. I personally prefer the writings of Bruce Schneier on the subject. The rough thing is, the professor of the class I'm taking picked this for the textbook... I've had to download errata, search out information online, and buy other books to try to cover the material. One of the exercises is to brute-force attack a misprinted encrypted message, and one has to know to go to the author's website to download the corrected ciphertext. That totally sucks in an $80 book.

An easy to read book on cryptography and security. Stallings illustrates concepts well, with lots of examples. If you're after mathematical depth, this book is not for you. This book is more about high level ideas and concepts.

This book is terrible. I am forced to read it for class and it's simply awful. If you want to learn cryptography get 'Applied Cryptography' by Bruce Schneier.
