快速有效的XML访问控制新方案

New scheme of XML-based access control for effective querying and quick updating

随着可扩展标记语言(XML)文档的广泛使用和用户安全意识的加强,XML数据的安全问题显得日益重要。结合索引/标记方案,设计了一种安全的、能有效查询和快速更新的XML访问控制新方案。该方案利用多种授权实现了权限不同的多个用户灵活、安全地查询XML文档数据;利用空对象和备注子节点实现了XML数据的删除和插入。

With the wide use of Extensible Markup Language （XML） documents and the strengthening security awareness, the security issues of XML data become increasingly important. The authors proposed a XML-based access control scheme, which implemented effective querying by combining indexing/labeling scheme. To achieve quick updating, the scheme used NULL objects to delete XML data and memo sub-nodes to insert XML data respectively.
