Open Social based group access control framework for e-Science data infrastructure

In an e-Science data infrastructure, access control is a vital component to facilitate the management of the collective data and computing resources shared by researchers from geographically distributed locations. But conventional virtual organization based access control frameworks are not suitable for self-organizing, ad-hoc and opportunistic scientific collaborations, in which scientists can easily set up group-oriented authorization rules across the administrative domains. Using the emerging OAuth2.0 protocol, this paper introduces a novel Open Social based access control framework to support ad-hoc team formation and user-controlled resource sharing. Our experiences with development of the framework in e-Science data infrastructure projects demonstrate that the proposed framework is a very promising approach to resource sharing in cross-domain e-science environments.
