Proof of Being Forgotten

The talk is same with the recent talk on OC3. Video can be found at:

Q&A during the talk:

Gary: Assumption on reusing TEE sandbox?

Hongbo: No, if not reuse TEE, still has leakage.

Gary: What is Zone, is it heap?

Hongbo: No only. E.g., secrets in stack and also in general purpose registers.

Gary: How to demonstrate/show the Proof of Being Forgotten? Attestation? Enclave hash?

Mingshen: PoBF is a statically verified property. We also consider to add dynamic traces for post-mortem auditing. Combined with the enclave hash and reproducible build, we can provide the proof before the execution statically, and after the execution dynamically.

Apache Teaclave (incubating) is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.
