Abstract: This paper made a systematic analysis on a few of current trust models, provided a new mixed authenticated trust model, and gave a particular frame and function design. Then the study carried out a simulation and property analysis of the new model. The simulation results indicate that the new mixed authentication model can resolve the defaults of the static key mechanism and improve the security of the grid authentication.
