H A Dpolyval-generic.c15 * modulus for finite field multiplication which makes hardware accelerated
30 * fields. This trick allows multiplication in the POLYVAL field to be
31 * implemented by using multiplication in the GHASH field as a subroutine. An

12 * than 128. We then compute p(x) = h^8m_0 + ... + h^1m_7 where multiplication
13 * is simply polynomial multiplication.
19 * multiplication is finite field multiplication. The advantage is that the
85 * extra multiplication of SUM and h^8.
175 * Compute schoolbook multiplication for 8 blocks
181 * I.e., the first multiplication uses m_0 + REDUCE(PL, PH) instead of m_0.
264 * Perform montgomery multiplication in GF(2^128) and store result in op1.

123 // this is incompatible with Karatsuba multiplication. Therefore, for

H A Dphy_qmath.c9 * Description: This function make 16 bit unsigned multiplication.
10 * To fit the output into 16 bits the 32 bit multiplication result is right
19 * Description: This function make 16 bit multiplication and return the result
20 * in 16 bits. To fit the multiplication result into 16 bits the multiplication
22 * is done to remove the extra sign bit formed due to the multiplication.
