Access Control Model in Migrating Workflow System with Site Service Alliance

The migrating workflow is a new direction within the workflow management area. The access control model in a migrating workflow system is one of the most important areas in the research. In the traditional access control model the instance needs to apply permission in each site. In this article, we present the conception of sites’ service alliances (SA) into the migrating workflow system to reduce the cost of access control. In the system, there are several s. The sites which belong to the same provide same service and resource to the instance. With conception of sites’ service alliances we adapt the migrating workflow system model and present a new access control model on it. In the new access control model, the instance applies permission for a sites’ service alliance. So the instance does not need to apply permission in each site. The cost of access control is reduced largely.
