Trustworthiness Technologies of DDSS

摘要

The most significant strategic development in information technology over the past years has been "trusted computing" and trusted computers have been produced. In this paper trusted mechanisms adopted by PC is imported into distributed system, such aschain of trust, trusted root and so on. Based on distributed database server system (DDSS), a novel model of trusted distributed database server system (TDDSS) is presented ultimately. In TDDSS role-based access control, two-level of logs and other technologies are adopted to ensure the trustworthiness of the system.
