Grids are positioned as systems which spread Internet environments with machines distributed across multiple organizations and administrative domains. Security has been the focus of the grid system recently. As an important part of security, trust in grid computing has been researched extensively. Based on subjective logic, a flexible trust model has been established to enhance the security of Grid system. A trust degree threshold function has been designed for dependent tasks. Furthermore, a trust management framework has been designed to manage this trust model.
