e-RPNL : Labeling Scheme for Efficient Secure Access Control
Dong-Chan An, Jin Young Kim, Seog Park · International Conference on Advanced Communication Technology · 2008
As efficient secure access control of XML data stream in ubiquitous environment has become very important, there is an increasing need to process a query. In this paper, we propose a labeling scheme for efficient secure access control method using e-RPNL (extended role-based prime number labeling) in XML data stream. The RPNL has some problems. For example, RPNL does not know a relationship between nodes such as parent-child relationship. We overcome some problems such as node relationship, dynamic XML update using e-RPNL. The e-RPNL supports the process of dynamic XML data without re-labeling existing labels.
