—One of the objectives of trusted computing is to provide remote attestation method that is able to confirm the status of remote platform or application. Existing property-based attestation is based on the strong-RSA assumption and the required key length is too long. What’s more, a considerable number of RSA-length operations having to be performed which lead to low computational efficiency. Bilinear parings-Based Attestation model, which based on elliptic curve discrete logarithm bilinear paring, can shorten the required key length and reduce bandwidth usage at the same premise of safety performance requirements, as well as ensure platform configurations not to be exposed to the platform while improving operating efficiency. On the other hand, the model includes many trusted computing platform parameters in order to resist replay attacks, and take use of information hiding technology to hide certificates and effectively preventing anyone with a source of certificate misuse of the certificate.
