Flexible Security Deployment in Smart Spaces
Smart spaces, which utilize publish and subscribe architectures as well as semantic information, promise to ease cooperation of heterogeneous devices. To make smart spaces feasible for open multi-user environments we must provide easy-to-use security solutions. In this paper, we focus on security deployment issues, particularly to credential establishment and configuration of access control. The paper concentrates on challenges caused by heterogeneity of devices as well as dynamic nature of users, authorities, and security policies. To address these issues, the paper describes how credentials can be deployed in Smart Space architecture and how access control policies can be generated using available semantic information. Finally, the paper describes security implementations for a Semantic Information Broker and for Device Interconnect Protocol.
