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.
