RBAC-based trusted access control model for grid
基于RBAC策略的可信网格访问控制模型*

As to the characteristics of grid environment,this paper analyzed the trust relationship among the grid entities and provided the method for computing the degree of trust,thus making some corresponding improvements in RBAC technology.It also put forward the trust grid access model based on RBAC.What's more,it offers structure,module and access control process in RTGM model.Trusted access control model enhances grid security in grid environment.
