In a large system, XML documents associated with it can be large and complicated. To manage access control in such a large and complicated system is very difficult. Recently, Access Policy Sheet (APS) [6] was introduced to provide a solution to access control for large XML systems. In this paper, we proposed a temporal access control scheme in APS where the propagation of authorization rights is assumed. The authorization policies can be automatically revoked when the associated time expires. We also provide conflict resolutions for our temporal authorization system.
