Summary on Grant Application Form |
|
Pubish/subscribe has emerged as the communication paradigm for supporting large scale distributed applications, whether widely distributed (intemetbased) or locally dense (pervasive). Pub/sub systems are reaching maturity but none as yet supports security. We will allow applications to share a pub/sub system by integrating role-based access control. Applications will be supported in defining roles and events, and policy to define which roles can advertise, publish and subscribe to which attributes of which events. Moreover, service level agreements will allow controlled sharing of messages between applications. The event service will itself be used to achieve immediate revocation of these privileges.Large-scale applications, including sensor-dense pervasive environments, generate large volumes of events. We will explore how meaningful high-level events can be specified by clients, and detected by a distributed service that aggregates/composes low-level events.In some applications the privileges associated with roles change as the application progresses. We will create a generic solution to this problem, integrating active databse and lightweight workflow technology, for example, for courseware delivery..Active database triggers will form an integral part of our event infrastructure, so that, for example, an update to someone's police record can be set up to trigger some action.Clients will be provided with convenient web interfaces and tools for specifying events, roles and policy.
