55 using optimized ARM assembler and NEON, when available.

58 tristate "SHA-384/512 digest algorithm (ARM-asm and NEON)"
62 SHA-512 secure hash standard (DFIPS 180-2) implemented
63 using optimized ARM assembler and NEON, when available.
66 tristate "Scalar AES cipher for ARM"
70 Use optimized AES assembler routines for ARM platforms.
72 On ARM processors without the Crypto Extensions, this is the
73 fastest AES implementation for single blocks. For multiple
74 blocks, the NEON bit-sliced implementation is usually faster.
76 This implementation may be vulnerable to cache timing attacks,
77 since it uses lookup tables. However, as countermeasures it
78 disables IRQs and preloads the tables; it is hoped this makes
79 such attacks very difficult.
81 config CRYPTO_AES_ARM_BS
82 tristate "Bit sliced AES using NEON instructions"
83 depends on KERNEL_MODE_NEON
84 select CRYPTO_SKCIPHER
90 Use a faster and more secure NEON based implementation of AES in CBC,
93 Bit sliced AES gives around 45% speedup on Cortex-A15 for CTR mode
94 and for XTS mode encryption, CBC and XTS mode decryption speedup is
95 around 25%. (CBC encryption speed is not affected by this driver.)
96 This implementation does not rely on any lookup tables so it is
97 believed to be invulnerable to cache timing attacks.

116 Use an implementation of GHASH (used by the GCM AEAD chaining mode)
117 that uses the 64x64 to 128 bit polynomial multiplication (vmull.p64)
118 that is part of the ARMv8 Crypto Extensions, or a slower variant that
119 uses the vmull.p8 instruction that is part of the basic NEON ISA.
