Is it possible to use CMT inside SGX enclave?

Open AmbitionXiang opened this issue 3 years ago • 2 comments

If results of CMT can only be gotten through untrusted OS, enclaves cannot trust the results. Is it possible to directly get the results inside enclaves without involving OS?

I don't think SGX deals with aspects of host OS provided telemetry. CMT is no different to metrics obtained through perf subsystem. Why do you need CMT capability inside a VM/SGX enclave? Is there a practical application for it?

Thank you for your reply! I'm thinking about...maybe we can construct an oblivious memory by combining CMT and CAT if they are compatible with SGX.

No update for few months. Closing the issue now. Please reopen if you have more questions.
