Product Description
This unique book explains the basic issues of classical and modern cryptography, and provides a self contained essential mathematical background in number theory, abstract algebra, and probability—with surveys of relevant parts of complexity theory and other things. A user-friendly, down-to-earth tone presents concretely motivated introductions to these topics. More detailed chapter topics include simple ciphers; applying ideas from probability; substitutions, transpositions, permutations; modern symmetric ciphers; the integers; prime numbers; powers and roots modulo primes; powers and roots for composite moduli; weakly multiplicative functions; quadratic symbols, quadratic reciprocity; pseudoprimes; groups; sketches of protocols; rings, fields, polynomials; cyclotomic polynomials, primitive roots; pseudo-random number generators; proofs concerning pseudoprimality; factorization attacks finite fields; and elliptic curves. For personnel in computer security, system administration, and information systems.

 A great book for anyone just starting to learn about codes August 27, 2000

This book is great for anyone just starting to learn about cryptology. It doesn't expect you to understand large amounts of mathematics, and goes through the necessary mathematics to understand the subject and problems presented. Additionally, this book has an answer key for selected problems (not just a few, but many problems), which makes it great for the person wanting to teach themselves the subject at their own pace. Also, it makes for a good reference for the person already familiar with cryptology. Finally, it is a great book for the experienced mathematician that wants to see modern/abstract algebra applied to a modern day subject.

I like the book quite a bit because of the actual down-to-earth language Garrett uses. It is very nice since I'm using it on my own time. There some errors in the book, however. He also selects only about 25% of the questions to anwer in the key. He could show about 50% and give an explanation on how to find the answer. Other than that, there is nothing wrong with the book and those problems shouldn't keep you from buying it.
Great buy! April 27, 2003

Other than a few 1st edition errors and too small of an anwer key, the book is definitely worth the money. It has a very down-to-earth style which is great if you're using the book on your own like me. I'm using this book for the Siemman's Westinghouse Scholarship Competition, and I think it is a great book for anyone interested in Cryptology, whether they like math or not.
A down to earth book!! December 12, 2002
I can't belive how much I like this book. It has great down to earth language and very helpful examples. If you are interested in cryptography but don't know where to start, then this is a book for you to pick up. Seriously, without the math, cryptography won't be the same. This is the book that has the math to help you dive into cryptography and build a good fundation before you swim toward the big ocean!
Paul is a very funny guy when he lectures, if u get a chance to go to his lecture, don't miss it.
Great book for everyone !! December 12, 2002
I liked the book very much. In fact, I think you should read it if your math is a bit rusty. Lots of simple examples are provided to support the ideas presented in the book. If you are new to cryptography or don't know where to start, I think this is the book for you. Paul is a guy that can make you laugh when he lectures boring math theory!!! If you get a chance to go to his lecture, don't miss it!
