RFR(S) JDK-8233741: AES Countermode (AES-CTR) optimization using AVX512 + VAES instructions

[Kamath, Smita]

Hi Vladimir,


As per Intel Architecture Instruction Set Reference [1] Vector AES (VAES) Operations will be supported in future Intel ISA. I would like to contribute an optimization for AES-CTR algorithm using AVX512+VAES instructions. This optimization is for x86_64 architecture that have AVX512-VAES enabled. I ran jtreg test suite with the algorithm on Intel SDE [2] to confirm that encoding and semantics are correctly implemented.


I, smita.kamath at intel.com<mailto:smita.kamath at intel.com> , Regev Shemy (regev.shemy at intel.com<mailto:regev.shemy at intel.com>) and Shay Gueron, (shay.gueron at intel.com<mailto:shay.gueron at intel.com>) are contributors to this code.
