Phoronix: ~5x Faster SM4 Cipher Performance With AVX/AES-NI Tuned Linux Kernel Code

Alibaba engineers are looking to mainline an x86_64 tuned version of the SM4 cipher that with making use of AVX and AES-NI can allow for a dramatic performance speed-up...

WAPI? It's useless even for Chinese.

The SM4 cipher is a cipher designed by China and only used in China.

That's still like 1/5 of the world population, plus the prospect of emerging market.

SM4 cipher is a cipher

Breaking news!

And here I was thinking the SM4 cipher was a peanut butter and jelly sandwich made in Paraguay

Plus lots and lots of business travelers. Just another reason that Linux makes a good Professional Business OS.

Thanks God it's not US spying crap.

I will never understand why they don't make AVX as hardcoded optimization

It's time to move on anyone use old hardware use LTS or stop updating software

Thanks God it's not US spying crap.

Yeah, now its Chinese spying crap, just like US spying crap but with a worse human right record.

It's not just "Linux will support it", it's also that "you can get ARM CPUs with intrinsic instructions", interest outside of China is probably going to be low; as it's not better than AES-128.

There's also 15 year old papers on its weaknesses: https://www.researchgate.net/publica...4_block_cipher
