* Support for Intel AES-NI intruction set
|
||||
* Author: Huang Ying <ying.huang@intel.com>
|
||||
*
|
||||
* Intel AES-NI is a new set of Single Instruction Multiple Data
|
||||
* (SIMD) instructions that are going to be introduced in the next
|
||||
* generation of Intel processor, as of 2009. These instructions
|
||||
* enable fast and secure data encryption and decryption, using the
|
||||
* Advanced Encryption Standard (AES), defined by FIPS Publication
|
||||
* number 197. The architecture introduces six instructions that
|
||||
* offer full hardware support for AES. Four of them support high
|
||||
* performance data encryption and decryption, and the other two
|
||||
* instructions support the AES key expansion procedure.
|
||||
*
|
||||
* The white paper can be downloaded from:
|
||||
* http://softwarecommunity.intel.com/isn/downloads/intelavx/AES-Instructions-Set_WP.pdf
|
||||
*
|
||||
* This file is based on engines/e_padlock.c
