operations in GF(2^8) represented as GF(2)[x]/w(x) where + * w(x)=x^8+x^6+x^3+x^2+1. We care about doing that because it's part of the + * definition of the RS matrix in the key schedule. Elements of that field + * are polynomials of degree not greater than 7 and all coefficients 0 or 1, + * which can be represented naturally by bytes (just substitute x=2). In that + * form, GF(2^8) addition is the same as bitwise XOR, but GF(2^8) + * multiplication is inefficient without hardware support. To multiply + * faster, I make use of the fact x is a generator for the nonzero elements, + * so that every element p of GF(2)[x]/w(x) is either 0 or equal to (x)^n for + * some n in 0..254. Note that that caret is exponentiation in GF(2^8), + * *not* polynomial notation. So if I want to compute pq where p and q are + * in GF(2^8), I can just say: + * 1. if p=0 or q=0 then pq=0 + * 2. otherwise, find m and n such that p=x^m and q=x^n + * 3. pq=(x^m)(x^n)=x^(m+n), so add m and n and find pq + * The translations in steps 2 and 3 are looked up in the tables + * poly_to_exp (for step 2) and exp_to_poly (for step 3). To see this + * in action, look at the CALC_S macro. As additional wrinkles, note that + * one of my operands is always a constant, so the poly_to_exp lookup on it + * is done in advance; I included the original values in the comments so + * readers can have some chance of recognizing that this *is* the RS matrix + * from the Twofish paper. I've only included the table entries I actually + * need; I never do a lookup on a variable input of zero and the biggest + * exponents I'll ever see are 254 (variable) and 237 (constant), so they'll + * never sum to more than 491. I'm repeating part of the exp_to_poly table + * so that I don't have to do mod-255 reduction in the exponent arithmetic. + * Since I know my constant operands are never zero, I only have to worry + * about zero values in the variable operand, and I do it with a simple + * conditional branch.
