Access control labeling scheme for efficient secure XML query processing

Abstract

Recently XML has become an active research area. In particular, the need for an efficient secure access control method of dynamic XML data in a ubiquitous data streams environment has become very important. In this paper, we propose the access control labeling scheme for efficient secure query processing under dynamic XML data streams. The proposed labeling scheme supports the process of dynamic XML data without re-labeling existing labels and secure query processing. We have shown that our approach is efficient and secure through experiments. © 2008 Springer-Verlag Berlin Heidelberg.
