中文简介: | 由于各种用户和应用程序都需要在XML文档中分发和共享信息,因此在无处不在的数据流环境中高效、安全地访问XML数据变得非常重要。本文提出了一种有效的安全的XML查询处理方法,利用基于角色的素数标记和XML分割来解决这两个问题。病历XML文档由于患者数量的增加,具有宽度无限增加而不是深度无限增加的特点。但是,基于角色的素数标记方法可以充分地管理文档的大小,使动态变化引起的维护成本降到最低。实验评估清楚地证明了我们的方法是有效和安全的。 |
课程简介: | As various users and applications require the distribution and sharing of information in XML documents, the need for an efficient secure access of XML data in a ubiquitous data stream environment has become very important. In this paper, we propose an efficient secure XML query processing method to solve the two problems by using role-based prime number labeling and XML fragmentation. A medical records XML document has the characteristic of an infinite addition in width rather than in depth because of the increment of patients. But a role-based prime number labeling method can fully manage the size of documents that increases to infinity and can minimize the maintenance cost caused by dynamic changes. Experimental evaluation clearly demonstrates that our approach is efficient and secure. |
