A Novel Design of Trusted Platform Control Module

Trusted platform module(TPM) proposed by TCG was a subordinate device and the root of trusted measurement was put into BIOS,which faces the threat to be tampered.In order to solve the problem,a novel design of Trusted platform control module(TPCM),in which the root of trusted measurement has been incorporated into the module.Therefore it is helpful to solve problems of protecting the root and the original point of measurement;meanwhile,a new kind of scheme is proposed based on the module,which establishes an active trust transitive architecture.Based on above implementation,the module shows a critical feature of controlling effect on whole platform.
