As one of the most significant cryptographic algorithms, the Advanced Encryption Standard (AES) will play a central role in securing information exchange and communication in the next decade. Though its basic elements are fully defined in terms of functionality, AES requires the best exploitation of implementation in order to achieve optimum performance on specific architectures. This paper focuses on Extensible Firmware Interface (EFI) which is being applied as the next generation firmware technology. We present a new AES usage model within framework of EFI/Tiano based on IA 32 platform, which is an efficient implementation with its improved performance.
