Digital rights management is designed to protect digital content usage from end to end.While,the hidden security problems in client system threaten the reasonable usage of digital contents.Through researching on trusted computing technology,a common architecture of DRM combined with trusted computing was presented.Especially,the application of trusted computing in license distributing and digital content usage was introduced.Then,an identity authentication and key agreement protocol for trusted DRM were designed,and also described with its security analysis.Through the protocol,license server can authenticate the DRM client and validate its integrity.Otherwise,the peer can obtain sharing key to protect the digital license distributing.
