摘要
DRM系统的安全性依赖于其信任组件的安全性,该信任组件处于非安全的环境,其安全模型与基于互联网的系统的安全模型有着本质的区别。本文讨论了当前DRM系统的信任组件所采用的安全技术,并着重分析了基于DRM的电子书管理策略和信息组件模型的开发,提出了一个基于机器硬件指纹识别的DRM技术方案,该模型的实现将对数字图书馆的构建具有重要的实际意义。
The security of the DRM system is depended on the security of its trust components,which is run in unsafe circumstance. Its security model is essentially different from the system based on Internet. We discuss the technology used by the confidential component of current DRM system,and emphasize on analyzing the development of eBook manage strategy and confidential components,which are based on DRM. This paper proposes a new method for DRM Trust Component based on the algorithm of hardware fingerprint recognition. The implement of this method will pave the way for the construct of the digital library.
