Author of a number of book reviews in his own right, has sent over a review of Bruce Schneier's Applied Cryptography, 2nd Edition. One of the best introductions to the field of cryptography this is a book well worth reading, even for those who simply want a better understanding of the potentials about cryptography, and what it's all about.Applied Cryptography, 2nd EditionauthorBruce SchneierpagespublisherJohn Wiley & Sonsrating8/10reviewerISBN0-471-11709-9summaryA fantastic introduction and a handy reference on one of computer science's most interesting fields.More than any other field in computer science, cryptography is associatedwith computer warfare. Recent international treaties define cryptographicalgorithms as weapons, and the laws of many countries prohibit either thedevelopment, the usage, or the export of cryptographic algorithms. Yet whilefeared by governments, cryptography is one of the most fascinating - and useful- fields of algorithmics. The whole point of cryptography is to solveproblems.
(Actually, that's the whole point of computers -something many peopletend to forget.) Cryptography solves problemsthat involve secrecy, authentication, integrity, and dishonestpeople. You can learn all about cryptographic algorithms andtechniques, but these are academic unless they can solve aproblem.Bruce Schneier's Applied Cryptography, in its second edition, isprobably the best introduction to the field. Office 2013 activator toolkit beta 2. Schneier is not merely an excellenttechnical writer, but also a researcherin the field; for example, he developedthe public-domain Blowfish encryption algorithm.
But unlike many works by otherresearchers, Schneier's work does not read like a dry paper for a scientificjournal. His writing is very enjoyable (though the jokes are overdone at times)and his explanations are almost always lucid.

Breaking a plate is a good example of aone-way function. It is easy to smash a plate into a thousand tinypieces. However, it's not easy to put all those tiny pieces backtogether into a plate.So, what good are one-way functions? We can't use them forencryption as is.
A message encrypted with the one-way functionisn't useful; no one could decrypt it. (Exercise: Write a message ofa plate, smash the plate into bits, and then give the bits to afriend. Ask your friend to read the message. Observe how impressedhe is with the one-way function.) For public-key cryptography, weneed something else.Generally, the book covers four main subjects: protocols, algorithms, sourcecode (in C), and politics. I have the first edition of this book, and I felt it was really good.have been meaning to get the second edition for awhile, but haven't got around to it yet.IMHO, some reasons why Schneier spends so much time dissecting DES are:. It's one of the most popular crypto algorithms in the world, despite its mediocre key length (and 3DES can help that).
It's really rather well designed for its day; it shows you the kind of skull sweat that goes into crypto algorithm design. As a result of (2), many of its design features are common to other algorithms, including many of the current AES candidates. Understanding this one can give you a handle on understanding a lot more of them.I never took the crypto course in my CS curriculum in college, but this book made me wish I had.Eric. Just thought I'd mention these:. counterpane.com, Bruce Schneier's company, which hosts a lot of info on e.g.
counterpane.com and the newer counterpane.com cipher. (Twofish is an AES candidate). NIST is working towards the nist.gov (AES), which is to take over DES' role as the US-government recommended shared key block cipher.
