TPM Based Remote Attestation of Video Security

In order to ensure the video can be received by the legal client without attack of frame dropping,frame rearranging, and so on, a remote attestation protocol of video security based on Trusted Platform Module (TPM) is proposed. The architecture of the remote attestation protocol is explained in detail. Video content hash algorithm which is based on Fourier-Mellin is put forward to authenticate the video frame contents in order to prevent the man-in-the-middle from fabricating the response of remote attestation. To improve the efficiency of remote attestation, an attestation mode of differentiable granularity is developed. The experiments prove the effectiveness of the video hash algorithm and also demonstrate the characteristics of the proposed attestation mode of differentiable granularity.
