Terminals security vulnerabilities makes DRM researches to focus on trusted computing technology in recent years, however, no efficient and practical trusted authentication protocol is presented, especially with formal proof. To attest the integrity when access to the DRM server, the DRM client need perform mutual authentication and key agreement with the server first, and then use the sharing key to encrypt the integrity values. A novel trusted authentication protocol based on SDIO smart card is presented together with its formal security proof. The proposed protocol is composed of registration phase, login phase, identity authentication and key agreement phase, and integrity attestation phase. In contrast to other corrective schemes through attack resisting analysis and computational cost analysis, the proposed scheme is able to provide greater security and practicality to guarantee the trust attestation for DRM.
