In order to enhance the security of terminals computer
this paper presents a design of the Removable Trusted Platform Module(RTPM) and a new architecture of trusted enhancement on general personal computer based on RTPM and its prototype.RTPM that connect with computer through USB can take over the control of booting and validate integrity of following bootstrap process.The architecture can accomplish trusted bootstrap of computer system completely supported by RTPM and broaden the trusted mechanism to operating system and applications.The architecture builds a trusted computing environment on general personal computer without modifying hardware platform and BIOS
