Use optimized AES assembler routines for ARM platforms.
|
|
|
|
On ARM processors without the Crypto Extensions, this is the
|
|
fastest AES implementation for single blocks. For multiple
|
|
blocks, the NEON bit-sliced implementation is usually faster.
|
|
|
|
This implementation may be vulnerable to cache timing attacks,
|
|
since it uses lookup tables. However, as countermeasures it
|
|
disables IRQs and preloads the tables; it is hoped this makes
|
|
such attacks very difficult.

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.
