GDS Certificate Manager Pull Model |
||||||
The CertificateGroups Object organizes the CertificateGroups supported by the CertificateManager. It is described in 7.8.4.6. CertificateManagers shall support the DefaultApplicationGroup and may support the DefaultHttpsGroup or the DefaultUserTokenGroup. CertificateManagers may support additional CertificateGroups depending on their requirements. For example, a CertificateManager with multiple Certificate Authorities would represent each as a CertificateGroupType Object organized by CertificateGroups Folder. Clients could then request Certificates issued by a specific CA by passing the appropriate NodeId to the StartSigningRequest or StartNewKeyPairRequest Methods.
CertificateGroups assigned by the CertificateManager to specific applications are persisted by PullManagement Clients. These Clients use the NodeIds to relate their local configuration to the CertificateGroup in the CertificateManager.
The StartSigningRequest Method is used to request a new a Certificate that is signed by a CA managed by the CertificateManager. This Method is recommended when the caller already has a private key.
The StartNewKeyPairRequest Method is used to request a new Certificate that is signed by a CA managed by the CertificateManager along with a new private key. This Method is used only when the caller does not have a private key and cannot generate one.
The FinishRequest Method is used to check that a Certificate request has been approved by an entity with access to the RegistrationAuthorityAdmin Role. If successful the Certificate and Private Key (if requested) are returned.
The GetCertificateGroups Method returns a list of NodeIds for CertificateGroupType Objects that can be used to request Certificates or Trust Lists for an Application.
The GetCertificates Method returns a list of Certificates assigned to the Application for a CertificateGroup.
The GetTrustList Method returns a NodeId of a TrustListType Object that belongs to a CertificateGroup assigned to an Application.
The GetCertificateStatus Method checks whether the Application needs to update the Certificate identified in the call.
The CheckRevocationStatus Method checks the revocation status of a Certificate.
StartSigningRequest is used to initiate a request to create a Certificate which uses the private key which the caller currently has. The new Certificate is returned in the FinishRequest response.
Signature
StartSigningRequest(
[in] NodeId applicationId
[in] NodeId certificateGroupId
[in] NodeId certificateTypeId
[in] ByteString certificateRequest
[out] NodeId requestId
);
|
Argument |
Description |
|
applicationId |
The identifier assigned to the Application record by the CertificateManager. |
|
certificateGroupId |
The NodeId of the CertificateGroup which provides the context for the new request. If null the CertificateManager shall choose the DefaultApplicationGroup. |
|
certificateTypeId |
The NodeId of the CertificateType for the new Certificate. If null the CertificateManager shall generate a Certificate based on the value of the certificateGroupId argument. |
|
certificateRequest |
A CertificateRequest used to prove possession of the Private Key. It is a PKCS #10 encoded blob in DER format. If the CertificateRequest is for an ApplicationInstance Certificate then it shall include all fields required by OPC 10000-6 such as the subjectAltName. |
|
requestId |
The NodeId that represents the request. This value is passed to FinishRequest . |
The call returns the NodeId that is passed to the FinishRequest Method.
The certificateGroupId parameter allows the caller to specify a CertificateGroup that provides context for the request. If null the CertificateManager shall choose the DefaultApplicationGroup. If the Application does not currently belong to the requested CertificateGroup the CertificateManager shall verify that the Application is allowed to join the CertificateGroup and then, if permitted, add the Application to the CertificateGroup. The CertificateGroup verification and assignment may occur anytime before FinishRequest returns success.
The set of available CertificateGroups are found in the CertificateGroups folder described in 7.9.2. The CertificateGroups allowed for an Application are returned by the GetCertificateGroups Method (see 7.9.7).
The certificateTypeId parameter specifies the type of Certificate to return. The permitted values are specified by the CertificateTypes Property of the Object specified by the certificateGroupId parameter.
The certificateRequest parameter is a DER encoded CertificateRequest. The subject, subjectAltName and Public Key are copied into the new Certificate.
If the certificateTypeId is a subtype of ApplicationCertificateType the subject conforms to the requirements defined in OPC 10000-6. The public key length shall meet the length restrictions for the CertificateType. If the certificateType is a subtype of HttpsCertificateType the Certificate common name (CN=) shall be the same as a domain from a DiscoveryUrl which uses HTTPS and the subject shall have an organization (O=) field.
The ApplicationUri shall be specified in the CSR. The CertificateManager shall return Bad_CertificateUriInvalid if the stored ApplicationUri for the Application is different from what is in the CSR.
The subject in the CSR may be ignored by the CertificateManager. The CertificateManager may update the subject to comply with policy requirements and to ensure global uniqueness.
Any bits set in basicConstraints or extendedKeyUsage fields in the CSR are ignored by the CertificateManager. The CertificateManager uses values that are appropriate and compliant with the specification.
For Servers, the list of domain names shall be specified in the CSR. The domains shall include the domain(s) in the DiscoveryUrls known to the CertificateManager.
This Method shall be called from an encrypted SecureChannel and from a Session that has access to the CertificateAuthorityAdmin Role, the ApplicationAdmin Privilege, or the ApplicationSelfAdmin Privilege (see 7.2).
If auditing is supported, the CertificateManager shall generate the CertificateRequested AuditEventType (see 7.9.12) if this Method succeeds or fails.

If the value contains a ‘/’ or a ‘=’ then it shall be enclosed in double quotes (‘”’). |
|
domainNames |
The domain names to include in the Certificate. If not specified the DiscoveryUrls are used to create suitable defaults. |

If the certificateType is a subtype of HttpsCertificateType the Certificate common name (CN=) shall be the same as a domain from a DiscoveryUrl which uses HTTPS and the subject shall have an organization (O=) field.
If the subjectName is blank or null the CertificateManager generates a suitable default.
The requested subject may be ignored by the CertificateManager. The CertificateManager may update the subject to comply with policy requirements and to ensure global uniqueness.
The domainNames parameter is list of domains to be includes in the Certificate. If it is null or empty the GDS uses the DiscoveryUrls of the Server to create a list. For Clients the domainNames are omitted from the Certificate if they are not explicitly provided.

CheckRevocationStatus Method is used to check the revocation status of an Certificate.
Clients or Servers may use this Method if the issuer Certificate has a crlDistributionPoint extension, an authorityInformationAccess extension (see RFC 6960) or the TrustList is configured to require online Certificate revocation checks (see 7.8.2.1).
The CertificateManager will typically use a protocol such as OCSP (see RFC 6960) to verify the Certificate status using the endpoint in the CDP extension, however, it may also optimize performance by maintaining a cache of recently verified Certificate and/or maintaining it’s own offline CRLs. The validityTime parameter provides guidance on how long a result can be kept in a local cache.
The caller shall perform all validation checks other than the revocation status check (see OPC 10000-4) on the Certificate before calling this Method. The CertificateManager shall check the Signature on the Certificate and may do additional validation.
This Method shall be called from an authenticated SecureChannel.
Signature

[in] ByteString certificate
[out] StatusCode certificateStatus
[out] UtcTime validityTime

|
Argument |

|
INPUTS |

certificate |
