AB  - XML has become the default standard followed for information exchange across organizations using the web. Any XML document can be viewed as an XML tree. A labeling scheme is necessary to uniquely identify every node of an XML document tree. Secure labeling scheme is preferred in XML content dissemination of publish/subscribe system. In this study, we propose a secure labeling scheme called Enhanced Dewey Coding (EDC). EDC labeling scheme is efficient in terms of storage space required to store labels and time needed for labeling. EDC labeling scheme also preserves the basic hierarchical structural relationships that exists among the nodes of an XML tree. In addition, EDC provides security without leaking the actual structure of the XML document. We implement EDC labeling scheme for various real-time XML documents that varies in document structure and size. Our experimental results show that the performance of EDC in memory space and labeling time is better than the existing method. We also identified optimal random value range for EDC by evaluating the results of EDC label size with various random value ranges.
