Advanced Encryption Standard New Instructions
(Intel
®
AES-NI)
The processor supports Intel Advanced Encryption Standard New Instructions (Intel
AES-NI) that are a set of Single Instruction Multiple Data (SIMD) instructions that
enable fast and secure data encryption and decryption based on the Advanced
Encryption Standard (AES). Intel AES-NI are valuable for a wide range of cryptographic
applications, for example: applications that perform bulk encryption / decryption,
authentication, random number generation, and authenticated encryption. AES is
broadly accepted as the standard for both government and industry applications, and is
widely deployed in various protocols.

AES-NI consists of six Intel SSE instructions. Four instructions, namely AESENC,
AESENCLAST, AESDEC, and AESDELAST facilitate high performance AES encryption and
decryption. The other two, AESIMC and AESKEYGENASSIST, support the AES key
expansion procedure. Together, these instructions provide a full hardware for support
AES, offering security, high performance, and a great deal of flexibility.

PCLMULQDQ Instruction
The processor supports the carry-less multiplication instruction, PCLMULQDQ.
PCLMULQDQ is a Single Instruction Multiple Data (SIMD) instruction that computes the
128-bit carry-less multiplication of two, 64-bit operands without generating and
propagating carries. Carry-less multiplication is an essential processing component of
several cryptographic systems and standards. Hence, accelerating carry-less
multiplication can significantly contribute to achieving high speed secure computing
and communication.

RDRAND Instruction
The processor introduces a software visible random number generation mechanism
supported by a high quality entropy source. This capability will be made available to
programmers through the new RDRAND instruction. The resultant random number
generation capability is designed to comply with existing industry standards in this
regard (ANSI X9.82 and NIST SP 800-90).

Some possible usages of the new RDRAND instruction include cryptographic key
generation as used in a variety of applications including communication, digital
signatures, secure storage, and so on.
