Trust management in large-scale distributed systems is an important enabling factor in the operation of these systems. In this paper, we discuss trust management in a Grid operating system, called XtreemOS. The paper presents the trust model underlying XtreemOS and discusses its underlying elements. We demonstrate how the trust services can be used to establish trust in a XtreemOS-based Grid and propose a couple of solutions for terminating trust. We also discuss the different alternative designs for the model and pros and cons of each alternative. Finally, we provide an overview of the design, implementation and performance evaluation of the trust services.
