Semantic-Driven Access Control Model

Existing access control models are unable to meet the requirements of a manufacturing system in network environment. In this paper a new model named semantic-driven access control model is established. Security problem induced by large system scale and dynamic collaboration can be met in this model through integrating semantic entity and filter using static settings to control dynamic resources. Moreover, constraint base for workflow is introduced into the model to support the workflow access control. All these factors make the model suitable for a networked manufacturing system.
