Abstract

Model Driven Architecture is an approach to increase the quality of complex software systems by creating high-level system models and automatically generating system architectures and components out of these models. We show how this paradigm can be applied to what we call Model Driven Security for inter-organizational workflows in e-government. Our focus is on the realization of security-critical inter-organizational workflows in the context of Web services, Web service orchestration and Web service choreography. Security requirements are specified at an abstract level using UML diagrams. Out of this specification security relevant artifacts are generated for a target reference architecture based on upcoming Web service security standards. Additionally, we show how participants of a choreography use model dependencies to map the choreography specifications to interfaces for their local workflows.
