[PATCH 0/2] crypto: implement SM4 for arm64 using special instructions

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

 



Patch #1 makes some preparatory changes so the C routines can be used as
a fallback by other drivers.

Patch #2 implements the SM4 core cipher using the special instructions
introduced as an optional extension by revision 8.2 of the ARM architecture.

Note that this does not implement cipher+chaining mode combinations as we
do for AES. This can be added later if desiresd.

Ard Biesheuvel (2):
  crypto: sm4 - export encrypt/decrypt routines to other drivers
  crypto: arm64 - add support for SM4 encryption using special
    instructions
