【Abstract】 To implement the integration of DRM with cloud storage technologies,the searchable encryption(SE)and proxy re-encryption(PRE)used in cloud storage security assurance were combined with DRM to create a cloud storage based digital rights management framework with the separation of copyright certificates and the digital contents.An appropriate protocol under this framework was proposed as well.Analysis showed that the proposed framework and protocol met the actual application requirements with applicability,adaptability and scalability features.更多还原
