Wenbo Mao. Many cryptographic schemes and protocols, especially those based on hy, have basic or so-called "textbook crypto" versions, as these versionsare usually the subjects for many textbooks on cryptography. This book takes adifferent approach to introducing cryptography: it pays much more attention n aspects of cryptography.

Leading HP security expert Wenbo Mao explains why "textbook" crypto schemes, protocols, and systems are profoundly vulnerable by revealing real-world-scenario attacks

Leading HP security expert Wenbo Mao explains why "textbook" crypto schemes, protocols, and systems are profoundly vulnerable by revealing real-world-scenario attacks. Next, he shows how to realize cryptographic systems and protocols that are truly "fit for application"-and formally demonstrates their fitness. Mao presents practical examples throughout and provides all the mathematical background you'll need. Coverage includes: Crypto foundations: probability, information theory, computational complexity, number theory, algebraic techniques, and more.

Modern Cryptography Theory and Practice

Modern Cryptography Theory and Practice. An up-to-date book on cryptography. The book caused serious concern at the NSA despite its lack of coverage of specific modern cryptographic practice, so much so that after failing to prevent the book being published, NSA staff were informed to not even acknowledge the existence of the book if asked. In the US military, mere possession of a copy by cryptographic personnel was grounds for some considerable suspicion.

Currently there is no good book on cryptography for the practitioner. Many of the venerable references are horribly outdated and contain deeply flawed information. I ordered Modern Cryptography:Theory and Practice on the assumption that it would bridge this gap. However, it falls short. Elliptic Curve-Cryptography, an increasingly important area, is not covered at all beyond definition of the groups. Secret key authentication gets only two short paragraphs, rather then the in-depth discussion it deserves, and HMAC is not presented correctly in those two paragraphs.

Efficiency is not discussed at all, and many of the failures of implemented systems (weak randomness, MAC-then-encrypt, RSA padding oracles) are not discussed. The book does spend quite a bit of time on protocols, which is nice, but doesn't offer an example of a protocol done completely correctly. Security reductions for modes of operation are non-existent: the sole security proofs are in the public key setting. The approach of "just send the key and encrypt the rest with it", used in many protocols for speed and security, is only briefly discussed after RSA-ODAP and Cramer-Shoup. Generic composition is not present.

These weaknesses turn what could be a great book into a merely good one. I would wait for DJB to finish his book instead of getting this one.

This book is a must have for anyone working in the fields of cyber security & cryptography.

I bought this book for a college-level security course (CS 161 at UC Berkeley). I use it for readings and problem sets, and so far, the reading has been pretty clear and straight-forward, as have been the problems. We'll see when we get into more complicated material...

At first glance I liked the structure of the book, the huge amount of different topics and the approach based on attacking/fixing protocols.

After reading a large part of the book I am extremely disappointed for the following two reasons:

1) The book is full of obvious flaws. As a researcher with a strong background in computational complexity, the chapter 4 about computational complexity appears to be something like a sad joke.
Just a short example which does not require a lot of background: In Definition 4.12 non-polynomially-bounded functions are introduced. Here the requirement is that the function obtains larger values than any polynomial for all sufficiently large n. A function which fulfills this requirement only for every second value is by definition not non-polynomially-bounded. And based on the definition of polynomially bounded functions in the next sentence it is therefore considered as polynomially bounded. That is ridiculous. According to these definitions a function f: N -> R with f(x) = 0 for odd values of x and f(x) = 2^x for even values of x, is considered to be polynomially bounded. That is just sad :(
2) The language is not of sufficient quality for a textbook. While the author is obviously not a native speaker, the publisher should have edited the text accordingly.

I am not sure whether I will continue reading this book or not. The later chapters seem to have a lot of potential, but I already lost my trust in the quality of the book.

Modern Cryptography is by far the best first text on cryptography I've ever seen, blowing books like Applied Cryptography out of the water. It's a clear treatment that focuses on building practical systems, focusing on how to avoid common pitfalls.
The focus of this book is the correct design of cryptographic protocols that resist attack. This is in contrast to books like Applied Cryptography, which focuses on the tools and the building blocks used to construct systems, glossing over how to use those things together to build strong systems. While the innards of block ciphers and so on can be interesting, Schneier himself is prone to saying something along the lines of, "The world is filled with insecure systems built by people who read Applied Cryptography". That is, in order to build secure systems with cryptography, one should understand how to use cryptographic tools properly. We do not need to know how the tools themselves work... we can take it for granted as long as we understand their behavior.
It must be said that the average person shouldn't be designing their own cryptographic protocols, either. One of the things this book does well is demonstrate the large number of non-intuitive ways in which cryptographic protocols can go wrong. For example, the chapters on authentication schemes demonstrate a large number of schemes authored by reputable cryptographers that turned out to have significant weaknesses.
For the above reason, this probably isn't a text that needs to be on everybody's desk. I would say it is essential for anyone who wants to understand why protocol design is so hard, and it is also valuable to the few people who will go on to build new protocols, particularly graduate students in cryptography.
Here's what I like about the book:
- Cryptography is a rapidly evolving field, and this book is quite up to date, covering AES and other recent protocols. This is quite in contrast to books like Applied Cryptography, which is painfully out of date.
- The text is pretty lucid, staying away from arcane mathematical symbols when possible, and explaining them well when not. While it's a bit more math-y and not quite as fun to read as Applied Cryptography, it is nearly as good in this respect, and the content is far better.
- It's the first book I've seen to do a good job covering the state of the art in provable security techniques. It introduces fairly recent provable security models, and does so in a way that it doesn't take a mathematician to understand.
- Its coverage of topics is great, particularly in that it spends much time examining real-world protocols such as SSL/TLS, SSH and Kerberos.
If you are in the target audience for this book, you won't regret buying it. Even at the $54.99 list price (which is what I paid, sadly), you shouldn't feel even remotely cheated, particularly considering the fact that there are shorter books with only a fraction of the content that cost a lot more.
