One of the important functionalities in trusted computing is platform attestation, which allows us to reporting the current configuration of the platform to a remote Challenger. As a result of single threaded access mode on Trusted Platform Module (TPM), the server platform needs to process integrity requests turn and turn about, and then an issue on response efficiency arises in practice. An improved attestation protocol based on batching has been proposed in this paper, which achieved integrity reporting by batching all requests that arrived within a short duration, and TPM need only one time signing operation.
