Abstract:

The existing chain-style, star-style, and tree-style trust transmission models, which are used for presenting the establishment process of trusted computing platform, can record the measurement results of the entities in the platform. Nevertheless, these models not only have some shortcomings in describing the invoking and dependence relationships between the entities, but also don’t focus on the time limitation of the integrity measurement, which might make the models be suffered from the threats such as TOC-TOU. To overcome these weakness, a new model for describing establishment process of trusted computing platform and integrity measurement is proposed, namely Measured Zone. This model can describe the integrity statuses comprehensively; describe the state transition and trust transmission flexibly; and reduce the time limitation of integrity measurement, which makes the beforehand measurement more secure.

Key words: trusted computing, trust transmission, integrity measurement, measured zone
