The Research Of Remote Attestation Based On The Trusted Cloud Platform

With the rapid development of Internet Technology, the Cloud Computing appeared in your eyes. As a new Internet application pattern,Cloud Computing integrate data centers of different regions to building the Cloud Platform with greater capacity and faster calculation speed. Cloud Platform can undoubtedly improve the lives of people. The users service the Cloud Platform, also undertake its risk. According to this questions, we should change our mind from passive to active. Trusted Computing regard him as a starting point. Remote attestation is one of the key technologies of Trusted Computing whose ultimate goal is to realize the trusted of the network environment. It expect to pass to the trusted of Terminal Platform to the network environment, to achieve the trusted communication between all users in the network, to improve the safety of the network environment.By researching the remote attestation of trusted cloud platform: Remote Attestation Model based on Privacy CA, Direct Anonymous Attestation Model, Remote Attestation Model based on Binary and Property Based Attestation, I chose the Property Based Attestation model to improve. I choose the Bilinear Pairings based on the Elliptic Curve Cryptography instead of RSA key system to improve the efficiency of encryption and decryption and the system security, put the ring signature theory into the Remote Attestation Model, build an anonymous signer set to protect the Issuer, improve the process of Setup, Join and Sign/Verify. It can’t be used in the Trusted Cloud Platform, because of the difference of participant members. By researching the v TPM in the Cloud Platform, I improve the participant members, agreement and procedure to make the model can be used in the Trusted Cloud Platform. I prove the security of this scheme; prove the efficiency of improved PBA model of remote attestation efficiency increased by experiments, camparing to the existing remote attestation model.
