Spatial Connector: Mapping Access Control Models for Pervasive Computing and Cloud Computing

Services on pervasive computing are delegated or offloaded to cloud computing platforms, because pervasive computing devices have only limited resources. However, access control models in pervasive computing environments and cloud computing platforms are different, where the former tends to be context-dependent and the latter to be subject-based, e.g., role-based access control (RBAC). To connect such different models, we propose a framework for managing context-aware services executed at pervasive computing and cloud computing. The framework is constructed as a world model for specifying contextual information in the real world. This paper describes the design and prototype implementation of the proposed model.
