基于可信计算平台的DRM应用研究

Research of DRM Application Based on Trusted Computing Platform

数字版权保护技术DRM已经成为数字网络环境下数字内容交易和传播的重要技术,用于保护数字内容的版权,控制数字内容的使用和传播。可信计算技术是确保终端系统安全与可信的技术。将可信计算平台引入DRM应用系统,提出了基于可信计算平台的DRM应用框架,讨论了可信任环境的建立,并描述了基于可信计算平台的DRM系统中数字内容的分发及策略的执行。

Digital rights management is becoming a key enabling technology to protect intellectual property of digital contents, control their dissemination and usage. Trusted Computing Technique guarantees the security and Trustworthiness of terminals. Introducing Trusted Computing Platform into DRM, We proposed architecture of DRM application based on Trusted Computing Platform, discussed the trusted enviranment＇s establishment, and described the dissemination of digital content and enforcement of policies based on the proposed application architecture.
