- AES cipher algorithms (FIPS-197). AES uses the Rijndael
- algorithm.
-
- Rijndael appears to be consistently a very good performer in
- both hardware and software across a wide range of computing
- environments regardless of its use in feedback or non-feedback
- modes. Its key setup time is excellent, and its key agility is
- good. Rijndael's very low memory requirements make it very well
- suited for restricted-space environments, in which it also
- demonstrates excellent performance. Rijndael's operations are
- among the easiest to defend against power and timing attacks.

- The AES specifies three key sizes: 128, 192 and 256 bits

- Bit sliced AES gives around 45% speedup on Cortex-A15 for CTR mode
- and for XTS mode encryption, CBC and XTS mode decryption speedup is
- around 25%. (CBC encryption speed is not affected by this driver.)
- This implementation does not rely on any lookup tables so it is
- believed to be invulnerable to cache timing attacks.
