[PATCH 0/6] crypto: ARM/arm64 - AES and ChaCha20 updates for v4.11

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This series adds SIMD implementations for arm64 and ARM of ChaCha20 (*),
and a port of the ARM bit-sliced AES algorithm to arm64, and 

Patch #1 is a prerequisite for the AES-XTS implementation in #6, which needs
a secondary AES transform to generate the initial tweak.

Patch #2 optimizes the bit-sliced AES glue code for ARM to iterate over the
input in the most efficient manner possible.

Patch #3 adds a NEON implementation of ChaCha20 for ARM.

Patch #4 adds a NEON implementation of ChaCha20 for arm64.

Patch #5 modifies the existing NEON and ARMv8 Crypto Extensions implementations
of AES-CTR to be available as a synchronous skcipher as well. This is intended
for the mac80211 code, which uses synchronous encapsulations of ctr(aes)
[ccm, gcm] in softirq context, which supports SIMD algorithms on arm64.

Patch #6 adds a port of the ARM bit-sliced AES code to arm64, in ECB, CTR
and XTS modes.

Ard Biesheuvel (6):
  crypto: generic/aes - export encrypt and decrypt entry points
  crypto: arm/aes-neonbs - process 8 blocks in parallel if we can
  crypto: arm/chacha20 - implement NEON version based on SSE3 code
  crypto: arm64/chacha20 - implement NEON version based on SSE3 code
  crypto: arm64/aes-blk - expose AES-CTR as synchronous cipher as well
  crypto: arm64/aes - reimplement bit-sliced ARM/NEON implementation for
    arm64
