In linux kernel since version 3.10 (release Date: 2013-06-30)
Use a faster and more secure NEON based implementation of AES in CBC,
CTR and XTS modes
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.
