Automated Creation of Inter-organizational Grid Virtual Organizations

The grid has emerged as a platform that enables inter-organizational Internet-based collaboration space recognized as virtual organization (VO). Building a VO, in an open environment as the Internet, necessitates tracing its boundaries. As a way to realize that, access control policy may be employed to authorize, control and forbid activities in order to achieve the different partners´ mutual benefits. Our goal being the dynamic creation of virtual organizations, is then associated with the automated generation of access control policy in a multiple access stakeholders´ environment. We proposed in recent works a virtual organization model specified using OrBAC (organization based access control model). In this paper we propose a methodology to dynamically build VOs based on our model. The different methodology steps are explained along with the associated related works which serve for implementing our model
