E.g., secrets in stack and also in general purpose registers.</p> <p>Gary: How to demonstrate/show the Proof of Being Forgotten? Attestation? Enclave hash?</p> <p>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.</p> <p><strong>Topic for the Next Meetup</strong></p> <ul><li>HyperEnclave in Ant Finance - Shuang Liu</li></ul> <h2 id="attendees"><a href="#attendees" class="header-anchor">#</a> Attendees</h2> <ul><li>Hongbo Chen</li> <li>Gary</li> <li>Ran Duan</li> <li>He Sun</li> <li>Ruide Zhang</li> <li>Weijie Liu</li> <li>Chan Zhao</li></ul></div></article></div> <div class="footer"> |
| 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. |
