GPUCC-CERT-01: Device certificate chain is validated to the NVIDIA root of trust¶
| Property | Value |
|---|---|
| Severity | high |
| Platform | NVIDIA GPU Confidential Computing |
| Lifecycle stage | attest |
| Trust boundary | attestation |
| Assurance | operator-declared |
| Mode | Passive: reads only the files and values you pass to the scan. |
What a failure enables¶
- Model keys released on a fabricated or replayed report
What it checks¶
It passes when:
- Verifier validates the device cert chain to the NVIDIA root of trust.
How to fix¶
- Enable full certificate-chain validation to the NVIDIA Device Identity CA in the verifier/NRAS policy; never trust a self-signed or operator-supplied device certificate.
- Enable full cert-chain validation to the NVIDIA Device Identity CA.
After the fix, scan again: the check should report PASS.
When it is not assessed¶
SKIP:
- No --gpu-verifier-policy specified; skipping check.
ERROR:
- Could not read/parse verifier policy: …
Scan inputs¶

| Option | Description |
