With the advent of various collaborative sharing mechanisms such as Grids, P2P and Clouds, organizations including private and public sectors have recognized the benefits of being involved in inter-organizational, multi-disciplinary, and collaborative projects that may require diverse resources to be shared among participants. In particular, an environment that often makes use of a group of high-performance network facilities would involve large-scale collaborative projects and tremendously seek a robust and flexible access control for allowing collaborators to leverage and consume resources, e.g., computing power and bandwidth. In this paper, we propose a federated access management scheme that leverages the notion of attributes. Our approach allows resource-sharing organizations to provide distributed provisioning (publication, location, communication, and evaluation) of both attributes and policies for federated access management purposes. Also, we provide a proof-of-concept implementation that leverages distributed hash tables (DHT) to traverse chains of attributes and effectively handle the federated access management requirements devised for inter-organizational resource sharing and collaborations.
