In a ubiquitous computing environment, devices host services that are accessed by anonymous users. This causes threats of resource abuse through malicious attacks or resource scarcity through unintentional excessive service invocations. In this paper, the secure resource control for service sharing is presented which depends on two basic functionalities: access control and soft-state management. Services are grouped into virtual communities for secure access. Service cooperation through external orchestration can only be done within a virtual community.
