摘要：

In order to cope with varying protection granularity levels of XML (eXtensible Markup Language) documents, we propose a TXAC (Two-level XML Access Control) framework, in which an extended TRBAC (Temporal Role-Based Access Control) approach is proposed to deal with the dynamic XML data. With different system components, TXAC algorithm evaluates access requests efficiently by appropriate access control policy in dynamic web environment. The method is a flexible and powerful security system offering a multi-level access control solution.
