摘要
文中在分析数字版权管理系统和传统访问控制三种模型不足的基础上,针对数字版权管理系统的结构特点,结合使用控制的ABC模型,提出了一种数字版权管理系统的使用控制模型——UCONonA1模型。并根据UCONonA1模型的特点设计了数字版权管理系统框架,给出了系统工作的流程以及系统实现的关键技术。通过应用该模型能够对权限进行动态分发,并能在使用的整个过程中持续实现对未授权访问的控制,防范资源被随意拷贝、再次分发给其他用户,保证了数字内容的合法使用。
According to the architecture characteristics of digital rights management system, a digital rights management usage control model - UCON onA1, combined with the ABC model of control, was put forword through analyzing the lack of digital rights management system and three types of traditional access control model. A framework of digital rights management system was designed based on the characteristics of model - UCON onA1. In addition, the system processes and key technologies for system were given. Application of this model could distribute the permissions dynamically. The continual control of unauthorized access could prevent resources from being copied, re- distributed to other users, which could guarantee the legitimate use of digital content.
