一个基于可信密码模块的数字版权管理方案

Digital Rights Management Scheme Based on Trusted Cryptography Module

分析可信计算密码支撑平台可信密码模块的功能和结构,在比较数字水印、防拷贝、加密、激活的数字版权管理技术的基础上,研究可信密码模块在数字版权管理中应用的优势,对数字版权作品的保护,提出用外接可信密码模块加强数字版权管理的方案,不仅与现有的数字版权管理技术兼容支持,而且有利于普及数字版权管理。

Function and structure of trusted cryptography module are analyzed, and based on the contrast of digital watermark, physical copy protection, encryption and product activation, we analyze the advantages of TCM application used in DRM. To protect the DRM works, we propose the method in which external TCM can strengthen DRM. The method is compatible with existing DRM technique, and will make for the popularization of DRM.
