Unified Extensible Firmware Interface (UEFI) is a new specification that defines a software interface between the platform firmware and the operating system. UEFI in the near future will replace the conventional Basic Input-Output System (BIOS). Along with this, Trusted Computing has emerged as a new and challenging research field in the domain of computer security. This asserts the need of Trusted Bootstrapping. Here a new idea of Trusted Bootstrapping using the USB key is presented which involves the scheme of Portable Trusted Platform Module, supported with UEFI technology. It aims to reduce motherboard modification and makes the system less vulnerable to human disruption.
