Subject: [PATCH v9 1/7] SP800-90A Deterministic Random Bit Generator

This is a clean-room implementation of the DRBG defined in SP800-90A.
All three viable DRBGs defined in the standard are implemented:

  • HMAC: This is the leanest DRBG and compiled per default
  • Hash: The more complex DRBG can be enabled at compile time
  • CTR: The most complex DRBG can also be enabled at compile time

The DRBG implementation offers the following:

  • All three DRBG types are implemented with a derivation function.
  • All DRBG types are available with and without prediction resistance.
  • All SHA types of SHA-1, SHA-256, SHA-384, SHA-512 are available for
  • the HMAC and Hash DRBGs.
  • All AES types of AES-128, AES-192 and AES-256 are available for the
  • CTR DRBG.
  • A self test is implemented with drbg_healthcheck().
  • The FIPS 140-2 continuous self test is implemented.
  • Additional cipher primitives, such as Serpent or Twofish, can be
  • added to the DRBG without changing the implementation. The only
  • change necessary is to the DRBG definition given in the cores[]
  • array.
