| Architecture: arm |
| |
| 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. |

| - CTR (Counter) mode (NIST SP800-38A) |
| - XTS (XOR Encrypt XOR with ciphertext stealing) mode (NIST SP800-38E |
| and IEEE 1619) |
| |
| 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.) |
| |
| The bit sliced AES code does not use lookup tables, so it is believed |
| to be invulnerable to cache timing attacks. However, since the bit |
| sliced AES code cannot process single blocks efficiently, in certain |
| cases table-based code with some countermeasures against cache timing |
| attacks will still be used as a fallback method; specifically CBC |
| encryption (not CBC decryption), the encryption of XTS tweaks, XTS |
| ciphertext stealing when the message isn't a multiple of 16 bytes, and |
| CTR when invoked in a context in which NEON instructions are unusable. |
