Intel's New AES Instructions for Enhanced Performance and Security

The Advanced Encryption Standard (AES) is the Federal Information Processing Standard for symmetric encryption. It is widely believed to be secure and efficient, and is therefore broadly accepted as the standard for both government and industry applications. If fact, almost any new protocol requiring symmetric encryption supports AES, and many existing systems that were originally designed with other symmetric encryption algorithms are being converted to AES. Given the popularity of AES and its expected long term importance, improving AES performance and security has significant benefits for the PC client and server platforms. To this end, Intel is introducing a new set of instructions into the next generation of its processors, starting from 2009. The new architecture has six instructions: four instructions (AESENC, AESENCLAST, AESDEC, and AESDELAST) facilitate high performance AES encryption and decryption, and the other two (AESIMC and AESKEYGENASSIST) support the AES key expansio...
