The document discusses the development of a security model for distributed service environments like smart spaces. The goals are to develop identification, authentication, authorization and access control mechanisms for smart space platforms. Specifically for the Smart-M3 platform, the presentation covers developing a HIP-based authentication agent, mapping the smart space RDF graph to a virtual file system for access control, and initial implementation and testing of these components in Smart-M3. Future work includes further developing and integrating the HIP agent and access control mapping into the Smart-M3 platform.
