Hi, I’m new to the confidential computation field and I’m try verifying the CC capability of Hopper arch on a environment with TDX+H200. I have configured the confidential VM by following the tutorial of the guide (https://docs.nvidia.com/cc-deployment-guide-tdx.pdf). Now, I call the Nvidia attestation sdk API to attest GPU, but get failed due to the send_ocsp_request call timed out. I use the local gpu verifier and find that it still rely on the service of RIM and OCSP, which need network access. However, our environment is air-gapped, I wonder is there any solution for attestation in an offline environment with network access limitation.
