Abstract

In the last few years, an increasing amount of si-structured data have become available electronically to humans and programs. In such a context, XML is rapidly erging as the new standard for si-structured data representation and exchange on the Internet. Securing XML data is then becoming increasingly important and several attpts at developing methods for securing XML data have been proposed. However, these proposals do not take into consideration scenarios where users want to query XML data by using complex query language. In this paper we propose an extension to our previous access control model handling the new standard query language XQuery, which is a powerful and convenient language designed for querying XML data.
