Cryptography in Maple and Mathematica

Question

Is Maple or Mathematica preffered over the other for Cryptography/Number Theory? What are the advantages for each in terms of this area of mathematics?

Also could someone compare and contrast between Maple and Mathematica in terms of the following branches of mathematics (briefly):

• Discrete (Combinatorics, Graph Theory, ...)
• Analysis (Real, Complex, ...)
• Algebra (Linear, Abstract, ...)
• Applied (differetial equations, modeling, ...)
• Logic

Answer 1

It depends, this is a loaded question.

There are unique packages for some of these areas.

See: http://en.wikipedia.org/wiki/Comparison_of_computer_algebra_systems

As for Maple vs. Mathematica, it is a matter of preference.

I think you should peruse their respective newsgroups, search for reviews and check out some of the CASs

Answer 2

You should also look at some of the examples in crypto at:

Answer 3

Here are some of the relevant Mathematica documentation links...

• Number Theory guide-page
• Discrete Mathematics guide-page
• Graphs and Networks guide-page
• Logic and Boolean Algebra guide-page

And some of the equivalent marketing pages...

• graph and network modelling
• discrete calculus
• number theory
• industrial strength boolean computation

Answer 4

In general, CASes are not designed to handle various type of logic (first order, higher order etc). There is a Logic package in Maple. This package handles sentential logic.

Please see http://en.wikipedia.org/wiki/Automated_theorem_proving for a list of existing software to handle logic.

Hope this helps.

Answer 5

I have heard that Sage is probably the best program there is for two subjects, number theory and graph theory. See this question on a Sage specific forum, with exact quote from the answer by kcrisman:

"If you are doing graph theory or serious number theory, you shouldn't even be asking the question of which package to use."

In other words. If you are doing graph theory or serious number theory, there is no question that Sage is the best.

It is open source and has many other open source programs built in. It's free, which is much better than Maple or Mathematica. It also uses Python which is a main-stream language so as you work in you are developing a skill that is helpful in other places. You can easily program new functions if you like, and can even contribute them to future versions of Sage if you want.

Here is an algebraic number theory book and elementary number theory book written by the creator of Sage. Both books have Sage code in them. Here is a cryptography book with a Sage appendix.
