摘要 随着消费电子产品的普及,家庭网络逐渐流行,但与此同时网络上数字内容的侵权问题也非常严重。提出了一种对家庭网络内数字内容进行版权保护的数字版权管理(DRM)系统。系统中,家庭网关设备负责管理家庭网络内的所有用户电子设备,并作为它们的代理与外部DRM服务器交互,以执行DRM功能。系统采用的组密钥技术可使得经过加密的数字内容只有合法用户设备才能解密并使用,而通过数字内容在用户设备之间的超级分发可实现家庭网络内的内容共享。 With the popularization of the consuming electronic products,home networks are prevailing gradually, at the same time the copyright infringement of the digital content in the network is very serious. A digital rights management (DRM) system for protecting the copyrights of digital contents in home networks was proposed. In the proposed system, the home gateway device is responsible for managing the user electronic terminals in the home network and interacting with the external DRM server to enforce DRM functions as their agent. The group key technique adopted by this system makes sure only the legal user terminals can decrypt the encrypted digital content and then consume, and the digital contents can be shared in the home network through the super distribution of the contents between the user terminals.
