SM4 optimization for ARM by ASIMD 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%.

Further acceleration for SM4-GCM on ARM This patch will allow the SM4-GCM function to leverage the SM4 high-performance CTR crypto interface already implemented for ARM, which is faster than current single block cipher routine used for GCM It does not address the acceleration of GHASH function of GCM, which can be a future task, still we can see immediate uplift of performance (up to 4X) Before this patch: type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes 16384 bytes SM4-GCM 186432.92k 394234.05k 587916.46k 639365.12k 648486.91k 652924.25k After the patch: SM4-GCM 193924.87k 860940.35k 1696083.71k 2302548.31k 2580411.73k 2607398.91k Signed-off-by: Daniel Hu <Daniel.Hu@arm.com> Reviewed-by: Tomas Mraz <tomas@openssl.org> Reviewed-by: Paul Dale <pauli@openssl.org> (Merged from https://github.com/openssl/openssl/pull/17814)

SM4 optimization for ARM by HW instruction This patch implements the SM4 optimization for ARM processor, using SM4 HW instruction, which is an optional feature of crypto extension for aarch64 V8. Tested on some modern ARM micro-architectures with SM4 support, the performance uplift can be observed around 8X~40X over existing C implementation in openssl. Algorithms that can be parallelized (like CTR, ECB, CBC decryption) are on higher end, with algorithm like CBC encryption on lower end (due to inter-block dependency) Perf data on Yitian-710 2.75GHz hardware, before and after optimization: Before: type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes 16384 bytes SM4-CTR 105787.80k 107837.87k 108380.84k 108462.08k 108549.46k 108554.92k SM4-ECB 111924.58k 118173.76k 119776.00k 120093.70k 120264.02k 120274.94k SM4-CBC 106428.09k 109190.98k 109674.33k 109774.51k 109827.41k 109827.41k After (7.4x - 36.6x faster): type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes 16384 bytes SM4-CTR 781979.02k 2432994.28k 3437753.86k 3834177.88k 3963715.58k 3974556.33k SM4-ECB 937590.69k 2941689.02k 3945751.81k 4328655.87k 4459181.40k 4468692.31k SM4-CBC 890639.88k 1027746.58k 1050621.78k 1056696.66k 1058613.93k 1058701.31k 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/17455)
