Trusted remote attestation scheme based on property

Traditional authentication methods are mainly based on digital certificates and password authentication method. Trusted Computing provides a platform-to-end operating environment, configuration credible means of assessment. In the TCG specification, the essential of the remote attestation is integrality validation. People called it as binary attestation or configure-based attestation. The two remote authentication projects are both authenticate to the current configure. But, to manage all the security configures is not feasibility. A composite property-based attestation protocol is proposed in the paper. The attestation protocol just proves the security attribution of systems, and does not to exposure system configuration to verifier. In this case, the security can be improved and more accord to the real requirements. This protocol combined the advantages of delegate-based authentication and certificate-based authentication, which can improve the reliability of authentication results and reduce the pressure of the authentication server.
