Improving Privacy of Property-based Attestation without a Trusted Third Party

The attestation model was modified, and the Pedersen Commitment Scheme was used again to hide the configuration of platform, so that the privacy leakage problem which then brings the computing complexity can be solved. The protocol is applicable to the case without Property Certification Authority, and can provide security and privacy of high level with higher usability and lower computing complexity.
