Research on Trusted Application Environment base on PTM

Abstract

Trusted Computing leverages Trusted Platform Module (TPM) as the root of trust to build secure computing environment so as to improve the security of terminals. But there are some security problems of user roaming and migration of sealed data because of binding between platforms and TPMs. Users oriented trusted computing model is built based on Portable Trusted Module (PTM). Trust chains in computing system is delivered effectively to end users based binding between user identities and PTMs. Trust measurement, trust storage and trust reporting based on PTM are also given in this paper.
