Luo, W., Liu, W., Luo, Y., Ruan, A., Shen, Q., Wu, Z..  2016.  Partial Attestation: Towards Cost-Effective and Privacy-Preserving Remote Attestations. 2016 IEEE Trustcom/BigDataSE/ISPA. :152–159.
In recent years, the rapid development of virtualization and container technology brings unprecedented impact on traditional IT architecture. Trusted Computing devotes to provide a solution to protect the integrity of the target platform and introduces a virtual TPM to adapt to the challenges that virtualization brings. However, the traditional integrity measurement solution and remote attestation has limitations due to the challenges such as large of measurement and attestation cost and overexposure of configurations details. In this paper, we propose the Partial Attestation Model. The basic idea of Partial Attestation Model is to reconstruct the Chain of Trust by dividing them into several separated ones. Our model therefore enables the challenger to attest the specified security requirements of the target platform, instead of acquiring and verifying the complete detailed configurations. By ignoring components not related to the target requirements, our model reduces the attestation costs. In addition, we further implement an attestation protocol to prevent overexposure of the target platform's configuration details. We build a use case to illustrate the implementation of our model, and the evaluations on our prototype show that our model achieves better efficiency than the existing remote attestation scheme.
