The processor supports Advanced Encryption Standard New Instructions (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). 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 AES 

support, 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. Accelerating carry-less multiplication 

significantly contributes to achieving high-speed secure computing and communication. 

The processor introduces a software visible digital random number generation 

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

programmers through the new RDRAND instruction. The resultant random number 

generation capability complies with existing industry standards (ANSI X9.82 and NIST 

SP 800-90). The instruction is described as RDRAND—Read Random Number in Volume 

2 of the Intel

 64 and IA-32 Architectures Software Developer’s Manual.

Some uses of the new RDRAND instruction include cryptographic key generation as 

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

storage, etc.
