摘要: Trust and reputation models play an important role in enabling trusted computations over large-scale distributed grids. Many have been recently proposed implemented within trust management systems. Nevertheless, the existing approaches usually assess performance of terms resource while less attention is paid to analysis security threat scenarios for such models. In this paper, we most critical threats a utility-based model The extended address these scenarios. With simulations that were run using data collected from EGEE Grid-Observatory project, analyse efficiency against threats.
