Workflow Based Dynamic Roles Constraint Model for Coordinated Mobile Computing Environment
Mobile computing systems introduce new requirements for role-based access control, which can not be met by using traditional RBAC. In this paper, a novel RBAC model of workflow based dynamic roles constraint relation is introduced to meet these requirements. This novel RBAC model formally describes the concurrent transaction logic by the extended predicate workflow model, and describes the dynamic constraint relations among the subtasks of workflows by analyzing the concurrent executive network of workflow. The static role constraint in the traditional RBAC was extended. The novel RBAC scheme is suitable for the workflow based mobile computing system. The analysis of the performance evaluating showed the novel RBAC model has favorable access control efficiency in the practical workflow based mobile computing environment.
