摘　　要：随着网络技术和电子商务的发展,数字权益管理逐渐成为数字产品使用、交易和传播的重要技术。然而,目前数字权益管理系统没有一个完全的解决方案。本文首先介绍了数字权益管理基本概念和必要条件。接着,描述了现有数字权益管理系统的主要组件,同时指出当前系统存在的限制。作为解决方案,本文提出了一个全新的三层数字权益管理体系结构,对各层进行了定义。然后,对提出的体系结构和现有体系结构之间进行关系对应,同时描述了三层体系结构的主要特征。文中最后指出了数字权益管理在今后的发展方向。With the expansion of the network and E-commerce, Digital Rights Management(DRM) becomes more significant in protecting any types of digital products and in controlling the distribution and usage of them. However, there are currentlyno complete solutions for DRM systems. In this paper, the basic concepts and the major requirements for DRM were reviewed at first. Secondly, the main components ofthe existing DRM architecture and the limitation shared by all current DRM systems were pointed out. As a solution, a three-layer architecture for DRM systems was proposed and the layers in this system were defined. Afterwards, the relations between the proposed architecture and the existing architecture were presented and some features of the three-layer architecture were introduced. Finally, the future work on DRM was described.
