摘要: The federation is a special case of open system where the resources are controlled and accessed by cooperation one or more roles in federation. needs few treatments like subset ownership (i.e. multiple user ownership) objects, dynamic access right allocation etc. can not be handled any combination mandatory, discretionary role-based control models MAC, DAC RBAC). This paper gives theoretical study on an model federating systems analysing nature subjects, objects their relationships; then proposes generic for system. safety proof shows that always remains safe state using proposed model.
