Abstract: We introduce a trusted computing technique for Distributed Database Server System (DDSS), and discuss the implementation of trusted authorization, the management logic of authority, and the processing of the authority-machine. In this paper, a new model of Trusted DDSS (TDDSS) is presented. In this system many new techniques are adopted, for example, mechanism of the chain of trust, role-based access control model, two-level of logs, trusted authorization and so on. At the same time, a new technique of trusted computing in the distributed computing system is given.

Key words: distributed database, trusted computing, role-based management, chain of trust
