sGUTS: Simplified Grid User Trust Service for Site Selection

Even though trust plays a significant role during decision-making in open collaborative environments, still Grid user trust mechanisms have not been widely deployed in Grid computing settings. In this paper, a conceptual framework that is an extension of a novel Grid user trust service (GUTS) is presented, which aims at leveraging Grid functionality with trust mechanisms with a special focus on achieving end-user trust in an intuitive and practical manner. Trust in GUTS is utilized during the grid site selection process, where sites are ranked based on expected service requirements for a user grid project. In the proposed conceptual framework, the center of the trust management process is the user who decides and specifies the needs of his/her project, which in turn are mapped to trust requirements.
