Abstract :
To further enhance the safety of BIOS, this paper present a new trust BIOS verified and self-recovery model with USBKEY in Unified Extensible Firmware Interface (UEFI). This model established a trust chain from the first stage of UEFI to the operating system by analyzing the process of UEFI startup. Thus the model narrowed the scope of the root of trust and substantially improved the safety of the BIOS. With the popularity of UEFI, this model has a good prospect in achieving security on computer system.
