It's possible that a vulnerable keymint implementation could lie about the security level. e.g. a vulnerable trusted OS could be coerced into claiming it is actually StrongBox. All certificates issued to StrongBox implementations have a StrongBox claim in their certificate (carried within the subject). Add a constraint that checks for this claim and matches it against the Google-signed certificate(s). PiperOrigin-RevId: 943985945

Add constraint enforcing SecurityLevel matching
It's possible that a vulnerable keymint implementation could lie about the
security level. e.g. a vulnerable trusted OS could be coerced into claiming
it is actually StrongBox.
All certificates issued to StrongBox implementations have a StrongBox claim
in their certificate (carried within the subject). Add a constraint that checks
for this claim and matches it against the Google-signed certificate(s).
