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 un-der 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.
