The Linux kernel configuration item CONFIG_CRYPTO_AES_ARM_BS
has multiple definitions:
arch/arm/crypto/Kconfig
The configuration item CONFIG_CRYPTO_AES_ARM_BS:
CONFIG_KERNEL_MODE_NEON
aes-arm-bs
, aes-arm-bs
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.
crypto/Kconfig
The configuration item CONFIG_CRYPTO_AES_ARM_BS:
