Hi,
I want to find a AES-CBC implementation using Intel SSSE3, because the CPU I works with have no AES-NI. I have to use SSSE3 to get better performance. There is a module in Openssl using SSSE3 to implement AES. According Openssl's test result, there are +28%/64% improvement between regular assembly code and SSSE3 assembly code.
But I can't find a implementation which available in kernel space and fit in Linux crypto API. Anyone have some info about this?
And I noticed that Linux-crypto are using SSSE3 to implement sha1,sha256,sha512, why not for AES?
Here is the info for SSSE3 AES implementation, http://shiftleft.org/papers/vector_aes/ and http://crypto.stanford.edu/vpaes/.
or you can read the Openssl code in Openssl\crypto\aes\asm\vpaes-x86.pl
Thank you for your time!
Regards
Shuai
