| 79 | Use a faster and more secure NEON based implementation of AES in CBC, | |
| 80 | CTR and XTS modes | |
| 81 | ||
| 82 | Bit sliced AES gives around 45% speedup on Cortex-A15 for CTR mode | |
| 83 | and for XTS mode encryption, CBC and XTS mode decryption speedup is | |
| 84 | around 25%. (CBC encryption speed is not affected by this driver.) | |
| 85 | This implementation does not rely on any lookup tables so it is | |
| 86 | believed to be invulnerable to cache timing attacks. | |
