Effectively implement AES for EFI/Tiano based on IA-32 Platform

The advanced encryption standard (AES) is one of the most important algorithms in modern cryptography. Although fully defined in terms of functionality, AES requires best exploitation to achieve optimum performance on specific architectures. Generally even highly optimized SW solutions are magnitude slower than dedicated HW solutions. Our work concentrates on extensible firmware interface (EFI) is being used as the next generation firmware technology contains much more benefits than legacy BIOS. To combine the unusually high speed with platform universality, we present a new usage model of AES for EFI/Tiano framework based on IA-32
