Design of a Role-based Trust-management Framework Abstract We introduce the RT framework, a family of Rolebased Trust-management languages for representing policies and credentials in distributed authorization. RT combines the strengths of role-based access control and trustmanagement systems and is especially suitable for attributebased access control. Using a few simple credential forms, RT provides localized authority over roles, delegation in role definition, linked roles, and parameterized roles. RT also introduces manifold roles, which can be used to express threshold and separation-of-duty policies, and delegation of role activations. We formally define the semantics of credentials in the RT framework by presenting a translation from credentials to Datalog rules. This translation also shows that this semantics is algorithmically tractable.

要求具备基本功能如下： （1）能够对角色信息进行添加、修改、删除、浏览等操作； （2）能够对权限信息进行添加、删除、修改和查询； （3）实现对角色的权限分配与管理； （4）系统操作简单，方便实用。 数据库在database文件夹中！

C# WinForm实现基于角色权限的菜单，vs2008或更高版本即可完美运行，winform实现的权限菜单。
