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. I know conditionals are expensive, but I couldn't + * see a non-horrible way of avoiding them, and I did manage to group the + * statements so that each if covers four group multiplications. */ + +static const byte poly_to_exp[255] = { + 0x00, 0x01, 0x17, 0x02, 0x2E, 0x18, 0x53, 0x03, 0x6A, 0x2F, 0x93, 0x19, + 0x34, 0x54, 0x45, 0x04, 0x5C, 0x6B, 0xB6, 0x30, 0xA6, 0x94, 0x4B, 0x1A, + 0x8C, 0x35, 0x81, 0x55, 0xAA, 0x46, 0x0D, 0x05, 0x24, 0x5D, 0x87, 0x6C, + 0x9B, 0xB7, 0xC1, 0x31, 0x2B, 0xA7, 0xA3, 0x95, 0x98, 0x4C, 0xCA, 0x1B, + 0xE6, 0x8D, 0x73, 0x36, 0xCD, 0x82, 0x12, 0x56, 0x62, 0xAB, 0xF0, 0x47, + 0x4F, 0x0E, 0xBD, 0x06, 0xD4, 0x25, 0xD2, 0x5E, 0x27, 0x88, 0x66, 0x6D, + 0xD6, 0x9C, 0x79, 0xB8, 0x08, 0xC2, 0xDF, 0x32, 0x68, 0x2C, 0xFD, 0xA8, + 0x8A, 0xA4, 0x5A, 0x96, 0x29, 0x99, 0x22, 0x4D, 0x60, 0xCB, 0xE4, 0x1C, + 0x7B, 0xE7, 0x3B, 0x8E, 0x9E, 0x74, 0xF4, 0x37, 0xD8, 0xCE, 0xF9, 0x83, + 0x6F, 0x13, 0xB2, 0x57, 0xE1, 0x63, 0xDC, 0xAC, 0xC4, 0xF1, 0xAF, 0x48, + 0x0A, 0x50, 0x42, 0x0F, 0xBA, 0xBE, 0xC7, 0x07, 0xDE, 0xD5, 0x78, 0x26, + 0x65, 0xD3, 0xD1, 0x5F, 0xE3, 0x28, 0x21, 0x89, 0x59, 0x67, 0xFC, 0x6E, + 0xB1, 0xD7, 0xF8, 0x9D, 0xF3, 0x7A, 0x3A, 0xB9, 0xC6, 0x09, 0x41, 0xC3, + 0xAE, 0xE0, 0xDB, 0x33, 0x44, 0x69, 0x92, 0x2D, 0x52, 0xFE, 0x16, 0xA9, + 0x0C, 0x8B, 0x80, 0xA5, 0x4A, 0x5B, 0xB5, 0x97, 0xC9, 0x2A, 0xA2, 0x9A, + 0xC0, 0x23, 0x86, 0x4E, 0xBC, 0x61, 0xEF, 0xCC, 0x11, 0xE5, 0x72, 0x1D, + 0x3D, 0x7C, 0xEB, 0xE8, 0xE9, 0x3C, 0xEA, 0x8F, 0x7D, 0x9F, 0xEC, 0x75, + 0x1E, 0xF5, 0x3E, 0x38, 0xF6, 0xD9, 0x3F, 0xCF, 0x76, 0xFA, 0x1F, 0x84, + 0xA0, 0x70, 0xED, 0x14, 0x90, 0xB3, 0x7E, 0x58, 0xFB, 0xE2, 0x20, 0x64, + 0xD0, 0xDD, 0x77, 0xAD, 0xDA, 0xC5, 0x40, 0xF2, 0x39, 0xB0, 0xF7, 0x49, + 0xB4, 0x0B, 0x7F, 0x51, 0x15, 0x43, 0x91, 0x10, 0x71, 0xBB, 0xEE, 0xBF, + 0x85, 0xC8, 0xA1 +};
