Nowadays, access control models take a system centric view of protecting resource, and they donpsilat take the context into account when controlling the permissions, such as RBAC. However, with the arrival of pervasive computing times, it requires thousands of applications to connect and communicate each other, which suggests not only noticing the protection of systematic resources but the context of the programmer. This article introduces the object of Actor and the dynamic trust model, expands the RBAC model, proposes the Actor and Trust-based dynamic access control model(ATBAC)that is based on the RBAC model, carries on the seal management to the users and the roles through the Actor, carries on modeling from the angle of the Actor and context, and carries on the dynamic management to the permissions based on Actor and context .According to the trust value of users, the user are assigned a group of roles, and decides the activation of the role and permission dynamically according to the context trust value .Because the different context trust value activates the different role and the permission, the user's access permission also changes along with it changing.
