Intrinsics for Carry-less Multiplication Instruction and Advanced Encryption Standard Instructions

The prototypes for the Carry-less multiplication intrinsic and the AES intrinsics are defined in the wmmintrin.hfile.

Carry-less Multiplication Intrinsic

The single general purpose block encryption intrinsic description is provided below.

Performs a carry-less multiplication of one quadword of v1 by one quadword of v2, and returns the result. The imm8 value is used to determine which quadwords of v1 and v2 should be used.

Corresponding Instruction: PCLMULQDQ

Advanced Encryption Standard Intrinsics

The AES intrinsics are described below.

Performs one round of an AES decryption flow using the Equivalent Inverse Cipher operating on a 128-bit data (state) from v with a 128-bit round key from rkey.

Corresponding Instruction: AESDEC

Performs the last round of an AES decryption flow using the Equivalent Inverse Cipher operating on a 128-bit data (state) from v with a 128-bit round key from rkey.

Corresponding Instruction: AESDECLAST

Performs one round of an AES encryption flow operating on a 128-bit data (state) from v with a 128-bit round key from rkey.

Corresponding Instruction:AESENC

Performs the last round of an AES encryption flow operating on a 128-bit data (state) from v with a 128-bit round key from rkey.

Corresponding Instruction: AESENCLAST

Performs the InvMixColumn transformation on a 128-bit round key from v and returns the result.

Corresponding Instruction: AESIMC

Assists in AES round key generation using an 8-bit Round Constant (RCON) specified in rcon operating on 128 bits of data specified in ckey and returns the result.

Corresponding Instruction: AESKEYGENASSIST
