Abstract

The goal of trusted computing proposed by TCG is to enhance the security of platform by the way of integrity measurement. TPM is a tamper-resistant hardware module designed to provide robust security capabilities like remote attestation and sealed storage for the trusted platform. But TPM has its limitation. It canpsilat be directly used in common PC current in use because of its interface with PC. A UsbKey is a USB device with capabilities of smart card. Extensible firmware interface (abbreviated as EFI) is intended as a significantly improved replacement of the old legacy BIOS. How to design and implement the driver of UsbKey based on EFI is what this paper focuses on. It is a basement for the trusted application.
