The improved research on property-based remote attestation

BPBA is a remote attestation model based on elliptic curve discrete logarithm bilinear paring, which includes attribute-configuration credential protocol, sign protocol, and verification algorithm. It 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 improved sign algorithm provides an effective model to avoid double counting, and a certificate revocation algorithm is also given effective solution when a certificate is invalid. BPBA includes more 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. Therefore, relative to the existing strong-RSA based property remote attestation model which needs longer key length, and has low computational efficiency, BPBA has a very good performance and algorithm improvements.
