Hi, what is the fastest way to compute galois field arithmetic on a modern computer using c or java. A galois field that has 2 m members is denoted by gf2 m, where m is an integer between 1 and 16 in this example. For example, if you apply the log function to a galois array, matlab computes the logarithm in the galois field for that galois array and not in the field of real or complex numbers. The tool is still in development but will be completed by the end of this summer. The gfmul function multiplies elements of a galois field. This example illustrates how to work with galois fields. If a and b are matrices of the same size, the function treats each element independently c gfmula,b, field multiplies a and b in gfp m, where p is a prime. You clicked a link that corresponds to this matlab command. Download galois field arithmetic python package for free. Cryptography software system using galois field arithmetic. Mathworks is the leading developer of mathematical computing software for engineers. As a result, when you manipulate the variable, matlab works within the galois field the variable specifies.
Hi there, i need to solve axb in an galois field environment and to my frustration i cannot get matlab to do this simple task. This project will implement galois field arithmetic in python language.
