How to generate a random binary permutation of a string of (length N) and (hamming weight M) in Verilog?

For example the module/function might be formatted like so

module perm(out, N, M);  input[31:0] N, M;  output[N-1:0] out;    // some algorithm...    endmodule  

Example: perm(X,4,2) out => 0110 or out => 1001 or out => 1010 etc...

In theory it should be able to output any of the binary permutations with an equal/even probability distribution, but for the time being I don't even know where to begin, any insight would be useful.
