[Kamath, Smita]

Hi All,

Could you please review AES-ECB implemented using AVX512+VAES instructions.

Thanks and Regards,

Hi Vladimir,

As per Intel Architecture Instruction Set Reference [1] Vector AES Encrypt and Decrypt Operations will be supported in future Intel ISA.  We would like to contribute optimizations for AES-ECB algorithm to support encryption and decryption operations using AVX512+VAES instructions. These optimizations are for x86_64 architecture that have AVX512-VAES enabled.

Shravya(cc'ed) and I are co-contributors. Shay Gueron(shay.gueron at intel.com<mailto:shay.gueron at intel.com>) and Regev Shemy (regev.shemy at intel.com<mailto:regev.shemy at intel.com>) are the authors of the algorithm.

I have tested the algorithm with Intel SDE [2] to confirm encoding and semantics are correctly implemented.



Please take a look and let me know if you have any questions or comments.
