| # NOC Root Certificate Transactions Design | ||
|
|
||
| ## User Stories | ||
|
|
||
| ### 1. Add NOC Root Certificate | ||
| A Vendor with DCL write privilege can submit a transaction to add a NOC Root certificate associated with their Vendor ID. | ||
|
|
||
| ### 2. Revoke NOC Root Certificate | ||
| A Vendor with DCL write privilege can submit a transaction to revoke a NOC Root certificate associated with their Vendor ID. | ||
|
|
||
| ## Certificate Schema | ||
|
|
||
| To distinguesh NOC root certificates from others, an `isNOC` boolean field will be added to the [certificates](https://github.com/zigbee-alliance/distributed-compliance-ledger/blob/master/proto/pki/certificate.proto) schema | ||
|
|
||
| ## Transactions | ||
|
|
||
| ### 1. ADD_NOC_X509_ROOT_CERTIFICATE | ||
| This transaction adds a NOC Root Certificate owned by the Vendor. | ||
|
|
||
| - Who can send: Vendor account | ||
| - VID-scoped NOC Root Certificate: The `vid` field in the certificate's subject must be equal to the Vendor account's VID. | ||
| - Validation: | ||
| - The provided certificate must be a root certificate: | ||
| - `Issuer` == `Subject` | ||
| - `Authority Key Identifier` == `Subject Key Identifier` | ||
| - No existing certificate with the same `<Certificate's Issuer>:<Certificate's Serial Number>` combination. | ||
| - If certificates with the same `<Certificate's Subject>:<Certificate's Subject Key ID>` combination already exist: | ||
| - The sender must match the owner of the existing certificates. | ||
| - The signature (self-signature) and expiration date must be valid. | ||
| - Parameters: | ||
| - cert: `string` - The NOC Root Certificate, encoded in X.509v3 PEM format. Can be a PEM string or a file path. | ||
| - In State: | ||
| - `pki/ApprovedCertificates/value/<Subject>/<SubjectKeyID>` | ||
| - `pki/NOCRootCertificates/value/<VID>` | ||
| - CLI Command: | ||
| - `dcld tx pki add-noc-x509-root-cert --certificate=<string-or-path> --from=<account>` | ||
|
|
||
| ### 2. REVOKE_NOC_X509_ROOT_CERTIFICATE | ||
|
There was a problem hiding this comment. I think it's an open question how Revocation should work here.
Open Questions; for now assume Soft-delete (revoked certificates are moved to something like ...noc/revoked/... path (similar to common Root certs, but specific collection for NOC Roots). Do we need to put revoked NOC Root into a collection with other revoked Root certs? |
||
| This transaction revokes a NOC Root Certificate owned by the Vendor. | ||
|
|
||
| - Who can send: Vendor account | ||
| - VID-scoped NOC Root Certificate: The `vid` field in the certificate's subject must be equal to the Vendor account's VID. | ||
| - Validation: | ||
| - A NOC Root Certificate with the provided `subject` and `subject_key_id` must exist in the ledger. | ||
| - Parameters: | ||
| - subject: `string` - Base64 encoded subject DER sequence bytes of the certificate. | ||
| - subject_key_id: `string` - Certificate's `Subject Key Id` in hex string format, e.g., `5A:88:0E:6C:36:53:D0:7F:B0:89:71:A3:F4:73:79:09:30:E6:2B:DB`. | ||
| - In State: | ||
| - `pki/RevokedNOCRootCertificates/value/<subject>/<subject_key_id>` | ||
| - CLI Command: | ||
| - `dcld tx pki revoke-noc-x509-root-cert --subject=<base64 string> --subject-key-id=<hex string> --from=<account>` | ||

| ## Query | ||
|
There was a problem hiding this comment.
|
||
|
|
||
| To retrieve NOC certificates by Subject and Subject Key Identifier, use the [GET_X509_CERT](https://github.com/zigbee-alliance/distributed-compliance-ledger/blob/master/docs/transactions.md#get_x509_cert) or [GET_ALL_SUBJECT_X509_CERTS](https://github.com/zigbee-alliance/distributed-compliance-ledger/blob/master/docs/transactions.md#get_all_subject_x509_certs:) query. | ||
|
|
||
| ### GET_NOC_X509_ROOT_CERTS_BY_VID | ||
|
|
||
| Retrieve NOC Root Certificates associated with a specific VID. | ||
|
|
||
| - Who can send: Any account | ||
| - Parameters: | ||
| - vid: `uint16` - Vendor ID (positive non-zero) | ||
| - CLI Command: | ||
| - `dcld query pki get_noc_x509_root_certs --vid=<uint16>` | ||
| - REST API: | ||
| - GET `/dcl/pki/noc-root-certificates/{vid}` | ||
|
|
||
| ### GET_ALL_NOC_X509_ROOT_CERTS | ||
|
|
||
| Retrieve a list of all of NOC Root Certificates | ||
|
|
||
| - Who can send: Any account | ||
| - Parameters: | ||
| - Common pagination parameters | ||
| - CLI Command: | ||
| - `dcld query pki get_all_noc_x509_root_certs | ||
| - REST API: | ||
| - GET `/dcl/pki/noc-root-certificates` | ||
|
|
||
| ### GET_REVOKED_NOC_X509_ROOT_CERTS | ||
|
|
||
| Retrieve revoked NOC Root Certificates associated with a specific Subject and Subject Key Identifier. | ||
|
|
||
| - Who can send: Any account | ||
| - Parameters: | ||
| - subject: `string` - Base64 encoded subject DER sequence bytes of the certificate. | ||
| - subject_key_id: `string` - Certificate's `Subject Key Id` in hex string format, e.g., `5A:88:0E:6C:36:53:D0:7F:B0:89:71:A3:F4:73:79:09:30:E6:2B:DB`. | ||
| - CLI Command: | ||
| - `dcld query pki get_revoked_noc_x509_root_certs | ||
| - REST API: | ||
| - GET `/dcl/pki/revoked-noc-root-certificates/{subject}/{subject_key_id}` | ||
|
|
||
| ## Questions | ||
| - Should the vendor add a revocation distribution point for NOC certificates? | ||
| - Should the following queries return NOC Certificate? | ||
| - [GET_ALL_SUBJECT_X509_CERTS](https://github.com/zigbee-alliance/distributed-compliance-ledger/blob/master/docs/transactions.md#get_all_subject_x509_certs) | ||
| - [GET_ALL_X509_ROOT_CERTS](https://github.com/zigbee-alliance/distributed-compliance-ledger/blob/master/docs/transactions.md#get_all_x509_root_certs) | ||
| - [GET_X509_CERT](https://github.com/zigbee-alliance/distributed-compliance-ledger/blob/master/docs/transactions.md#get_x509_cert) | ||
| - Should an additional field be added to the certificate schema to distinguish NOC certificates from common PAAs/PAIs? | ||
| - Should a revoked NOC Root Certificate be stored in the revoked list, or should it be completely removed? Additionally, if a NOC Root Certificate is revoked, should it be returned in the existing [GET_ALL_REVOKED_X509_ROOT_CERTS](https://github.com/zigbee-alliance/distributed-compliance-ledger/blob/master/docs/transactions.md#get_all_revoked_x509_root_certs) and [GET_REVOKED_CERT](https://github.com/zigbee-alliance/distributed-compliance-ledger/blob/master/docs/transactions.md#get_revoked_cert) queries? | ||

Need to decide, if we want to distinguish NOC certificates from common PAAs/PAIs (for example when querying it by Subject+SubjectKeyId).
Open Questions; for now assume YES (needed).
For example, we can introduce a new field to the Certificate data model (https://github.com/zigbee-alliance/distributed-compliance-ledger/blob/master/proto/pki/certificate.proto): bool NOC
