Need a Comprehensive Cryptography Text

  1. Jan 15, 2012 #1
    As per the title, I need a cryptography book that does not shy away from math. To me it seems like many crypto books are scared of presenting the theory from a mathematician's perspective. I was recommended Cryptography : Theory and Practice by Stinson, can anyone comment on it?

    Any help is very appreciated :)

    You mean besides the Bruce Schneier ones?

    I'm assuming you're alluding perhaps to Practical Cryptography by Schneier and Ferguson? It seems to cover quite a few introductory topics, but exactly how "mathy" does it get? I'll have to drop by our library today to check them out, but recommendations from experienced people is always a plus. Some of the reviews on Amazon for the above book sort of worry me about the quality and mathematical rigor of the text (I take them with a grain of salt nonetheless). Here are a few excerpts from reviews:

    "The book has surprisingly little math, if any."

    "Recently I spoke with a PhD, from Brown, who performed decades of research in number theory. He recommended "Cryptography in C and C++," by Michael Welschenbach. He also said "I don't know why people think Applied Cryptography is such a good book. He [Schneier] doesn't seem to understand the mathematics very well.""

    "At the end of the book, they warn you that a good
    implementation is so hard that you really should hire an
    expert to do it"

    Why am I learning about cryptography if I'm just going to let someone else do the work for me? What kind of book is this??

    Ideally I need something along the lines of "Cryptography and Number Theory". I've already taken an intro course in number theory, so it does not have to be a very basic text. Thanks again for the help.

    I'll take that as a "yes" then...

    You realise that Practical Cryptography is not the only book he's written?
    Applied Cryptography?

    But it kinda depends what you want to know - "cryptography" is pretty broad so "introductory" type books will be math-light, describing the field, and "practical" type books will be more like cookbooks - a bit of background theory and a lot of recipes.

    OTOH: once you have an overview, you can refine your focus.
    Getting these from a library is probably a good idea.

    Ah, you want to know about mathematical codes and algorithms and the fundamentals of how they work? Then Neal Koblitz would be it :) Cheers wisvuze.

    Thanks wis, for some reason I didn't immediately see those on amazon.ca. It's pretty much exactly what I wanted to go along with my other book. :smile:
