The Study of Access Control Model Using XML

Abstract

XML, the Extensible Markup Language, had become an important tool for both storage and exchange of data. As the applied areas of XML had been widen gradually, the security problems of XML became a main concern. Hence, the study of access control using XML had been an important topic of security study of XML nowadays. In this paper, we would first made a brief introduction of access control using XML, and some requirements of XML access control would be included. After that, we would give a detail presentation of an access control model using XML, and point out the most significant feature of it. Finally, we analyzed the direction and difficulty in the study of access control using XML, and then illustrate the practical significance of the study.

“…On the other hand, Access Control is considered a high-level approach to security policies that provide secure access to data and both encryption and signature are designed to handle communication security [31]. The authors in [32] proposed an XML access control to guarantee application safety and they proved that the advantages of using XML access control are a fine-grained access on an element level, the use of different safety strategies over different parts on the same document, the use of a safety process for encryption and digital signature, and protecting network resources.…”

“…XML, on the other hand, is used in many areas to store, retrieve, and provide data and information in an organized format [31] and it is considered one of the most extensively used data exchange languages across the internet [32] because of its immense compatibility in transit [33]. There are many advantages in using XML data representation, such as: the notions of elements, it is extensible, it allows the separation of display and content and it can present complex structure in an easy way [32]. Nevertheless, XML falls short of guaranteeing the security by itself, and hence, a secure application framework is needed as a precondition to have it programmed as needed [32].…”
