Product Description

Review

“Coverage and clarity of material are excellent in this book [Stallings]. This is an appropriate level for first-year graduate students.” — Shambhu Upadhyaya, University at Buffalo

“Bill Stallings has long been known as someone who can explain complicated topics well. I’ve been reading his books since the mid-80’s and they are always well done.” — Mike Kain, Drexel University

“The text [Stallings] compares well to other texts in both theory and application…Stallings’ problems are the best that I’ve seen.” — William Bard, University of Texas

“This is one of the best textbooks [Stallings] designed for a combined introduction to cryptology and network security for computer scientists and engineers that I have seen. Mathematics coverage is adequate…virtually no mathematical background is expected.” — David Arnold, Baylor University

“The text [Stallings] does a very good job of giving a subject overview while including details of various algorithms.” — Edward Allen, Wake Forest University

Product Description

William Stallings' Cryptography and Network Security: Principles and Practice, 5e is a practical survey of cryptography and network security with unmatched support for instructors and students.

In this age of universal electronic connectivity, viruses and hackers, electronic eavesdropping, and electronic fraud, security is paramount. This text provides a practical survey of both the principles and practice of cryptography and network security. First, the basic issues to be addressed by a network security capability are explored through a tutorial and survey of cryptography and network security technology. Then, the practice of network security is explored via practical applications that have been implemented and are in use today. An unparalleled support package for instructors and students ensures a successful teaching and learning experience.

The new edition has been updated to include coverage of the latest topics including expanded coverage of block cipher modes of operation, including authenticated encryption; revised and expanded coverage of AES; expanded coverage of pseudorandom number generation; new coverage of federated identity, HTTPS, Secure Shell (SSH) and wireless network security; completely rewritten and updated coverage of IPsec; and a new chapter on legal and ethical issues.

Not outstanding 16 April 2007
By CompEngGradStudent - Published on Amazon.com
Format:Hardcover
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.

Worst writing ever 30 Oct 2008
By rbt_austin - Published on Amazon.com
Format:Hardcover
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.

up to date on using cryptography 27 Aug 2006
By W Boudville - Published on Amazon.com
Format:Hardcover
Stallings presents an updated education on cryptography. With a secondary emphasis on network security. In the cryptographic sections, there is a strong mathematical flavour. The narrative is not a high level, management-type discussion. It favours the professional mathematician and programmer, and ideally the intersection of these two skill sets.

Unlike some other books on cryptography, here considerable space is also given to hash functions. These can sometimes be used as an alternative to a full encrypt/decrypt approach. If you are designing a system, you should ponder carefully whether a hashing approach might suffice. Usually if you only need to authenticate a message or item. Since, as the book relates, for all the complexity of the various hash algorithms, hashing is far simpler and faster than public key encryption. And there is no problem with key revocation. Another great simplification.

The book covers the latest work on hashing. It appears that the 160 bit hash methods, like SHA-1, can now have collisions induced, as found by researchers at Tsinghua University. (Though the text doesn't appear to credit them.) Suggesting a migration to longer bit methods or to a more intricate method.

One surprising feature of this 4th edition is that PKI is mentioned here, unlike earlier editions. PKI has been around long enough and is important enough that I would've thought the 3rd edition of the book would have covered it.

The last sections of the book, on network and system security, are less mathematical. But to offset this, as it were, they require somewhat of a background in understanding the Internet Protocol and in the systems administration of a subnet of computers. Maybe the simplest advice to understand and implement is for a sysadmin to install and regularly run a password checker against the users' passwords.
