Daniel Olmedilla, Omer F. Rana, Brian Matthews, and Wolfgang Nejdl. Security and Trust Issues in Semantic Grids. In Semantic Grid: The Convergence of Technologies. Dagstuhl Seminar Proceedings, Volume 5271, pp. 1-11, Schloss Dagstuhl – Leibniz-Zentrum für Informatik (2006)


Grid computing allows sharing of services and resources accross institutions. However, current Grid security mechanisms for authentication and authorization are too rigid and they lack the ability to determine how ``trustworthy'' the result obtained from a specific provider is likely to be. This paper describes the different facets associated to Trust and identifies the need for Trust Management approaches in the context of Virtual Organizations lifecycle and resource access control in the Grid.
