Research of Trust Model based on Autonomous Domain

In order to resolve the security problems due to the dynamics and uncertainty of grid environment, a trust model based on autonomous domain is developed in this paper, it discriminates the trust relationships between entities in the same autonomous domain and in different domains and handles the two different trust relationships in different approaches. By doing this, the trust relationships between entities can be evaluated more precisely, thus can resolve security problems exist in grid environment more effectively, which can be verified by simulated experiments
