Analysis and Application for Integrity Model 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 platform in this paper. By combinning access control model with information flow model, we put forward a combined process-based lattice model to enforce security. This model 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 and managed correctly,the integrity of the computer’s hardware and sofware has been mainfained,so does the confidentiality and authenticity.Moreover, a relevant implementation of the model is explained.
