Access Control in Service Compositions

Pervasive applications are entering the mainstream, but at the present time, exhibit significant security weaknesses. Service-driven architectural approaches facilitate the development of pervasive applications, however, security with respect to access control and data privacy of pervasive applications are currently not managed comprehensively from design time through run time. This chapter presents a use case emphasizing the security challenges for pervasive applications and proposes a novel, generative architectural approach, to include security in pervasive applications at design time. This is a model-driven approach based on models pertaining to access control management that respect the temporal constraints relating to pervasive applications. The approach is implemented with a design and runtime environment and the results of the validation applied to the pervasive use case are presented.
