Hi Henk, Frank, Michael, Bob, thanks for this document.
I have a question regarding the IEEE 802.1AR-based of the description. Here is what I understand for use of certificates from 802.1AR (with my wording because RFC 2119 language is often missing in the 1AR spec): * The DevID certificate subject field is always present, but can be empty. An IDevID certificate subject field MUST be non-null and SHOULD include a unique device serial number encoded as the serialNumber attribute. The subject field can contain information identifying the supplier or manufacturer of the device. * IDevIDs SHOULD use the GeneralizedTime value 99991231235959Z in the notAfter field. * The subjectAltName extension MAY be present in both DevID certificates and DevID intermediate certificates. If a DevID certificate includes a subjectAltName, that field should include a HardwareModuleName. When a TPM is used to provide DevID module functionality the IDevID certificate contains a subjectAltName that uses a HardwareModuleName to identify the TPM, the hwType identifying the TPM Version and the hwSerialNum containing the TPM Serial Number. * All certificates contain the authorityKeyIdentifier (as a non-critical extension). * Intermediate certificates contain the subjectKeyIdentifier, as a non-critical extension. The subjectKeyIdentifier extension SHOULD NOT be included in DevID certificates. * If a critical keyUsage extension is included in the IDevID, it MUST include digitalSignature. The keyUsage extension MAY include keyEncipherment. Is my reading of IEEE 802.1AR correct?
