Project Outline

DyVOSE is a 2-year project funded by the Joint Information Systems Committee (JISC) involving the National e-Science Centre at both the University of Glasgow and Edinburgh, the University of Salford and EDINA. Its intention is to explore the establishment of scalable Virtual Organisations (VOs) in the domain of e-Science education. VOs allow shared use of computational and data resources by collaborating institutions through grid technologies. Currently, the establishment of a VO in the Grid community is primarily achieved through comparison of an entities’ name with an Access Control List which confirms the user’s identity. This process (authentication) says nothing about the accessibility of remote resources for this entity (authorization), and lacks scalability when applied to large scale Grids for industry or education.

DyVOSE will prototype and apply technologies supporting the dynamic (as opposed to static) delegation of authority needed to create scalable VOs. Static delegation involves contacting a central authority to register local managers who are then able to assign privileges to subordinates. Dynamic delegation gives local managers the power to allocate privileges to subordinates as required, without having to contact a central manager. This Privelege Management Infrastructure (PMI) model delivers a federated, scalable model of security authorization supporting the dynamic establishment of trust between members and resources involved in VOs.

The project will investigate extensions to the PERMIS infrastructure to issue Attribute Certificates (ACs) to Graduate students in the upcoming Grid Computing module of the Advanced MSc. at the University of Glasgow, and e-Science investigators at the e-Science Institute (e-SI) in Edinburgh. These ACs will be used to control (authorize) access to e-Science computational and data resources such as ScotGRID.

The DyVOSE project flyer (written for AHM2005) is available in Power Point.
