Abstract

This paper describes the workflow authorization model for workflow management system, which integrates RTBAC and multilevel security model, and presents authorization model for a multilevel security workflow in the multilevel secure environments. The model adds the presentation of security level and task dependence and reforms the authorization rule for the improved model. At last, analyses the model, and in order to find the correct and safe way for execution, the source of task dependencies was analyzed based on the semantic category.
