This patch optimizes SM4 for ARM processor using ASIMD instruction It will improve performance if both of following conditions are met: 1) Input data equal to or more than 4 blocks 2) Cipher mode allows parallelism, including ECB,CTR,GCM or CBC decryption This patch implements SM4 SBOX lookup in vector registers, with the benefit of constant processing time over existing C implementation. It is only enabled for micro-architecture N1/V1. In the ideal scenario, performance can reach up to 2.7X When either of above two conditions is not met, e.g. single block input or CFB/OFB mode, CBC encryption, performance could drop about 50%. The assembly code has been reviewed internally by ARM engineer Fangming.Fang@arm.com Signed-off-by: Daniel Hu <Daniel.Hu@arm.com> Reviewed-by: Paul Dale <pauli@openssl.org> Reviewed-by: Tomas Mraz <tomas@openssl.org> (Merged from https://github.com/openssl/openssl/pull/17951) |
