This series of patches adds ARMv8 implementations of SM4 in ECB, CBC,
CFB and CTR modes, both for ARMv8 with Crypto Extensions and for plain
ARMv8 NEON.
NEON is a general-purpose SIMD instruction set under ARMv8, and SM4
acceleration instructions are optional supported by Crypto Extensions.
Patch 1 exports the constant array in the SM4 software implementation,
sm4_sbox are used for the tbl/tbx instruction lookup table in the NEON
implementation, sm4_fk and sm4_ck are used for the key expansion in the
CE implementation.
Patch 2 renamed the existing sm4-ce to sm4-ce-cipher, which is a
single-block CE algorithm implementation that does not support the mode.
This naming rule follows the AES algorithm in the same directory.
Patch 3 introduces an SM4 accelerated implementation of plain NEON.
Patch 4 introduced the SM4 CE instruction set implementation.
In order to be more intuitive, the following compares the performance of
the four algorithms sm4-generic, sm4-neon, sm4-ce-cipher, and sm4-ce,
their performance is from low to high.
Benchmark on T-Head Yitian-710 2.75 GHz, the data comes from the 218
mode of tcrypt. The abscissas are blocks of different lengths. The
data is tabulated and the unit is Mb/s:
