Analysis and Application for Integrity on Trusted Platform

摘要

To build a trusted platform based on Trusted Computing Platform Alliance (TCPA)' s recommendation, we analyze the integrity mechanism for such a PC platfoim in this paper. By combinning access control model with information flow model, we put forwarda combined process-based lattice model to enforce security This moelel creates a trust chain by which we can manage a series of processes from a core root of trust module to some other application modules In the model, once the trust chain is created andmanaged cor-rectly, the integrity of the computer's hardware and sofware has bctn maintained, so does the confidentiality and authenticity. Moreover, a relevant implementation of the model is explained.
