Book 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.

Essential book on the mathematics of cryptography.......2006-06-20

This wonderful book lies between the layman's approach of "The Code Book" and "Applied Cryptography: Protocols, Algorithms, and Source Code in C", which takes an algorithmic approach to cryptography but glosses over the mathematical details. It is great for people who already understand the use of various cryptographic algorithms as depicted in "The Code Book", but want to understand the underpinning mathematics before they implement cryptography in code. It is the best of the applied math books on the subject, since it manages to explain the mathematics behind cryptography without getting bogged down in proofs. If cryptographic algorithms and implementations are your business, all three books are essential reading.

This book is a college level mathematics text that does a pretty good job of explaining the mathematics involved without assuming a lot in the way of background, but a preliminary course in abstract algebra would certainly be helpful. If I have any criticism of the book it is that there is a scarcity of actual numerical examples versus the multitude of unsolved exercises left to the student. I would recommend this book to anyone interested in the mathematics of cryptography.

NOTE: A second edition of this book is due in February 2007. Preliminary information shows it to be 100 pages longer than this edition. Thus, if you have to buy the first edition now, you might want to get a used one and demand a lower price due to the limited lifespan this edition has.

Difficult to understand.......2006-05-06

I took this course at the U of Minn (where the author is a professor). He has a reputation of being a good professor and a good guy (and I have no reason to doubt it). Unfortunately, his book is very hard to understand. While packed chock full of information, it is written in a **very, very** dense style. It makes a lot of assumptions about your prior knowledge and there are few examples to illustrate the theory. While this may be OK for a grad student in math (or even a bright senior), it is definitely not sufficient for a non-math major and most undergrads.

Great buy!.......2003-04-27

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.

Actually 4.6.......2003-04-27

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.

Excellent book on cryptology.......2003-04-16

Very good book. His explanation is very clear.
I recommand to anyone who wants to learn cryptology.
I think computer scientist will get the most benefits from
this book.
