digital signal processing software. FMA improves performance in face detection,

professional imaging, and high performance computing. Gather operations increase

vectorization opportunities for many applications. In addition to the vector extensions,

this generation of Intel processors adds new bit manipulation instructions useful in

compression, encryption, and general purpose software.

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, such as 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.

Intel AES-NI consists of six Intel SSE instructions. Four instructions, 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

supporting AES; offering security, high performance, and a great deal of flexibility.

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.

The processor supports Intel

®

 Secure Key (formerly known as Digital Random Number

Generator (DRNG)), a software visible random number generation mechanism

supported by a high quality entropy source. This capability is available to

programmers through the 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 RDRAND instruction include cryptographic key generation

as used in a variety of applications, including communication, digital signatures,

secure storage, and so on.

Intel Transactional Synchronization Extensions (Intel TSX). Intel TSX provides a set of

instruction set extensions that allow programmers to specify regions of code for

transactional synchronization. Programmers can use these extensions to achieve the
