摘要
有效的访问控制是数字版权管理(DRM:Digital Rights Management)的基础和前提。针对传统DRM方案在静态授权、粗粒度方面的不足,以UCON(Usage Control)过程控制模型的基本方法为基础,设计新的DRM授权规则。该规则通过细分主客体属性和权利类型,建立细粒度的授权,通过访问过程中属性判断、责任判断和条件判断实现DRM授权的过程动态性。
Effective access control is the basis and prerequisite for digital rights management( DRM).In view of the deficiency of traditional DRM scheme in static authorization and coarse-grained,The design of new DRM authorization rules is based on the basic method of process control in usage control( UCON) model.The fine-grained authorization in the new rules can be realized by subdividing the attribute of subject and object and subdividing the type of rights,and the dynamic process authorization of DRM can be implemented by the judgment of attributes,obligations and conditions.
