Feng Wei-nin · 2015
The main content of existing delegation authorization model is about whether the delegatee can execute the delegated assignment(privilege),and the trust of the delegator's platform is not mentioned.In view of this,the paper presented a delegation authorization security protocol based on remote attestation under multimedia environment.Multimedia contents' trusted delegation authorization can be guaranteed in the protocol.This protocol not only ensures delegator and the multimedia server trust in delegatee's authentication and platform integrity,but also achieves the trusted access to the multimedia.Delegation verification,message interactions between entities were stated.The potential attacks were enumerated and analysed.The delegation authorization protocol based on remote attestation applied in DRM realizes the trusted delegation and the functions are more perfect compared to the existing protocols.
