Abstract(in English) | Current approaches for access control incur massive computational costs when XML documents are large and share the same structure. We propose a novel access control model with our prototype implementation to perform a fine-grained access control on both the structural level and the data level. The access control model has a pre-process and a runtime process to decrease runtime computational costs. During the pre-process, we compute a path-table from role/group-specified access control policy. The path-table is a table of pairings of target paths and access conditions. During the runtime process, the access condition of the requested path is looked up from the path-table and evaluated for accessibility check. Furthermore, this model supports access control on arbitrary descending paths in an XML document and also a group of arbitrary nodes that restricted by a given condition. |
