156
157 On ARM processors without the Crypto Extensions, this is the
158 fastest AES implementation for single blocks. For multiple
159 blocks, the NEON bit-sliced implementation is usually faster.
160
161 This implementation may be vulnerable to cache timing attacks,
162 since it uses lookup tables. However, as countermeasures it
163 disables IRQs and preloads the tables; it is hoped this makes
164 such attacks very difficult.

181
182 Bit sliced AES gives around 45% speedup on Cortex-A15 for CTR mode
183 and for XTS mode encryption, CBC and XTS mode decryption speedup is
184 around 25%. (CBC encryption speed is not affected by this driver.)
185
186 The bit sliced AES code does not use lookup tables, so it is believed
187 to be invulnerable to cache timing attacks. However, since the bit
188 sliced AES code cannot process single blocks efficiently, in certain
189 cases table-based code with some countermeasures against cache timing
190 attacks will still be used as a fallback method; specifically CBC
191 encryption (not CBC decryption), the encryption of XTS tweaks, XTS
192 ciphertext stealing when the message isn't a multiple of 16 bytes, and
193 CTR when invoked in a context in which NEON instructions are unusable.
