基于使用控制的数字版权保护研究

Research on the Digital Right Protection Based on the Usage Control

通过将UCONABC(usage control)模型引入到典型的DRM(Digital Rights Management)方案中,设计新的DRM方案。采用基于公钥加密体制的数字证书方案实现DRM系统中各参与方之间的相互验证和安全、有效、可追踪的信息传输,依托UCONABC模型实现DRM客户端更加灵活有效的资源使用控制。

A new program for Digital Rights Management（DRM） is designed by introducing the usage control model（UCONABC） into the typical DRM program.By implementing the digital certificate based on the public crypto method for the parties of DRM system,the safe,effective and traceable information transport are realized,the new program will realize more flexible and effective usage control for DRM clients with the help of UCONABC model.
