A Grid authorization model for science gateways
Abstract
Since the number of TeraGrid Science Gateways is expected to
grow at least an order of magnitude in the next few years, a
lightweight gateway deployment model is sought, one that
facilitates growth but meets the security requirements of the
TeraGrid. To this end, we present a new authorization model for
science gateways based on the community account model. This
authorization model significantly increases the information flow
between the gateway and the resource provider, without requiring
new wire protocols or extensive new middleware infrastructure.
Instead, the model complements existing technology and promises
to leverage emerging federated identity deployments directly.
