The grid security is an important component, and it directly affects the development of the grid and the practical application of grid system software. As a kind of tool, GSI(Grid Security Infrastructure) provides some services such as authentication, and access control and so on. and there's a trust relationship among the subject and object in advance. With the development of grid, in which the interaction scopes of nodes have exceeded the original intradomain this relationship has not met the grids' needs for security already. Some new access control strategies on grid environment based on trust and security grade were given. In this article, the subject and the object were extended, the classification and the reputation grade were extended and the concepts of organization security classification and organization reputation grade were defined. Through their reasonableness analysis and research, the strategies are improved and expanded about existing access control strategies, that can be apply to the grid environment, there has some positive significance about grid security research.
