Plan to extend SGX remote attestation to DCAP/ECDSA attestation?

Open ligangwangx opened this issue 3 years ago • 4 comments

According to Intel SGX Remote Attestation Portal, SGX EPID-based remote attestation is not available on 3rd Gen Xeon-SP (codenamed Ice Lake). 3rd Gen Xeon-SP only supports ECDSA-based attestation. Does the Crust community have a plan to support ECDSA-based attestation, so that Crust can run on 3rd Gen Xeon-SP to leverage its more powerful performance and much larger EPC size?

Hi folks, this is a blocking issue for crust users to leverage 3rd Gen Xeon-SP's powerful performance and large EPC size. We have several engineers who could help on this. Please contact me, and we can discuss how to solve this issue. Thanks!
