- * Definitions:
- *  GF    Galois Extension Field GF(2^128) - finite field where elements are
- *        represented as polynomials with coefficients in GF(2) with the
- *        highest degree of 127. Polynomials are represented as 128-bit binary
- *        numbers where each bit represents one coefficient.
- *        e.g. polynomial x^5 + x^3 + x + 1 is represented in binary 101011.
- *  H     hash key (128 bit)
- *  POLY  irreducible polynomial x^127 + x^7 + x^2 + x + 1
- *  RPOLY irreducible polynomial x^128 + x^127 + x^126 + x^121 + 1
- *  +     addition in GF, which equals to XOR operation
- *  *     multiplication in GF
- *
- * GF multiplication consists of 2 steps:
- *  - carry-less multiplication of two 128-bit operands into 256-bit result
- *  - reduction of 256-bit result into 128-bit with modulo POLY
- *
- * GHash is calculated on 128-bit blocks of data according to the following
- * formula:
- *    GH = (GH + data) * hash_key
- *
- * To avoid bit-reflection of data, this code uses GF multipication
- * with reversed polynomial:
- *   a * b * x^-127 mod RPOLY
- *
- * To improve computation speed table Hi is precomputed with powers of H',
- * where H' is calculated as H<<1 mod RPOLY.
- * This allows us to improve performance by deferring reduction. For example
- * to caclulate ghash of 4 128-bit blocks of data (b0, b1, b2, b3), we can do:
- *
- * __i128 Hi[4];
- * ghash_precompute (H, Hi, 4);
- *
- * ghash_data_t _gd, *gd = &_gd;
- * ghash_mul_first (gd, GH ^ b0, Hi[3]);
- * ghash_mul_next (gd, b1, Hi[2]);
- * ghash_mul_next (gd, b2, Hi[1]);
- * ghash_mul_next (gd, b3, Hi[0]);
- * ghash_reduce (gd);
- * ghash_reduce2 (gd);
- * GH = ghash_final (gd);
- *
- * Reduction step is split into 3 functions so it can be better interleaved
- * with other code, (i.e. with AES computation).
