In the Multimedia Mobile Edge Computing (MMEC) environment, cryptography technology is used to ensure secure transmission of multimedia data when Terminal accesses to MMEC or Terminal accesses to the central cloud. However, the problem of the participants’ identity authentication and integrity measurement can not be solved. Therefore, in this paper, a novel remote attestation model and protocol is proposed, which introduces mutual anonymous identity authentication, mutual integrity measurement and verification between Terminal and MMEC as well as between MMEC and cloud. Moreover, the proposed protocol guarantees data security and identity security of the platform, as well as integrity state maintenance when MMEC interacts with Terminal. We make a thorough security analysis and performance simulation over the proposed protocol. Security analysis shows that the proposed protocol is superior to the other two similar schemes in terms of privacy protection ability and anti-attack ability. Performance simulation results demonstrate that the remote attestation protocol with non-intensive requests state achieve much higher efficiency.
