intel - OpenSSL ECC gf2m modification to apply PCLMULQDQ instruction -


i'm trying modify openssl code in order use pclmulqdq instruction accelerate gf2m operations, described in intel white paper
intel polynomial multiplication instruction , usage elliptic curve cryptography

the paper suggests modifying following functions in crypto/bn/gf2m.c:

  • int bn_gf2m_mod_arr()
  • int bn_gf2m_mod_mul_arr()
  • int bn_gf2m_mod_sqr_arr()
  • int rshift1()

with code snippets in appendix. how should it? read snippets , had no clue how modify openssl code.
