Refactor primitives

• Make sure to have different implementations of AES for different purposes

  • PRF (deterministic, no IV, can be ECB mode)
  • Encryption (randomized, IV, no ECB)
  • PRG (deterministic, no IV, incremented counter)
  • Hash (from PRF)

• Also, make sure AES uses AES-NI instruction.

• Also, fix PRG to pre-fetch more pseudo random bytes than requested and cache them.

• Also, create low-bitness PRP for LewiORE (that works for 2, 4, 8 bits) as a on-the-fly generated table. Compare this to Feistel.

• Make sure scheme operation do not share cache.
