Confidential Attestation: Efficient in-Enclave Verification of Privacy Policy Compliance [article]

Weijie Liu, Wenhao Wang, Xiaofeng Wang, Xiaozhu Meng, Yaosong Lu, Hongbo Chen, Xinyu Wang, Qingtao Shen, Kai Chen, Haixu Tang, Yi Chen, Luyi Xing
2020 arXiv   pre-print
Our model is inspired by Proof-Carrying Code, where a code generator produces proof together with the code and a code consumer verifies the proof against the code on its compliance with security policies  ...  So its compliance with privacy policies as expected by the data owner should be verified without exposing its code.  ...  Security Policies Without exposing its code for verification, the target binary needs to be inspected for compliance with security policies by the bootstrap enclave.  ...
