CCA-CERT-01: CCA token is signed by a trusted Arm CCA platform

Property Value
Severity critical
Platform Arm CCA fleets
Lifecycle stage hardware
Policy P-04: Attestation evidence is fresh and fully verified
Evaluated from Evidence sent to the service (collector bundles or registry scans), not from a cloud API scan.

What it checks

It passes when:

  • Platform token signed by a CPAK this fleet trusts; it binds the realm attestation key that signed the realm token.

How to fix

  • Treat this realm as untrusted, or add the platform's CPAK (from the silicon vendor's endorsement) to the fleet if it is yours.

After the fix, scan again: the check should report PASS.
