Abstract: In a mobile computing environment, distributed business processes are executed in varying contexts. Context-aware access control mechanisms help to protect sensitive data and services in mobile application scenarios. Context constraints are a means to consider context information in access control decisions. In this paper, we integrate context constraints with process-related role-based access control (RBAC) to support the secure and context-dependent task execution. In particular, we specify a formal metamodel for process-related and context-aware RBAC models. Subsequently, we define a domain-specific extension for UML Activity diagrams that enables the integrated modelling of context constraints and business processes. In addition, we implemented a software platform that enables the specification and enforcement of process-related context-aware RBAC policies.
