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

摘要： 主要介绍了分布式数据库服务器系统中的可信研究，并讨论了其中有关可信授权的实现、权限的管理逻辑以及授权机的具体运行过程，给出了可信分布式数据库服务器系统的模型。系统中采用了信任链机制、基于角色的访问控制模型、两级日志、可信认证等技术，同时给出了可信在分布式计算机系统中的实现技术和途径。
