    Smart spaces are dynamic environments for sharing information e.g. in personal, building, or public networks. Key challenges for smart spaces include security and interoperability between heterogeneous devices, from high-end PCs to embedded gadgets and sensors. We propose a novel security architecture, which enables heterogeneous devices to share data in controlled manner. Centralized information brokering device is used to measure security level of published information. These measurements are then used to authorize information access. Hence, the architecture enables devices to share information with the same security level even when these devices do not have interoperable security protocols. We propose policy configuration and deployment models, which are feasible and usable with embedded devices. We also describe our practical experiences from implementing the proposed security solution for smart spaces.
