1. Introduction
As per Certification Policy (CP)
ThisThe structure of the Resource PKI (RPKI) is congruent with the number resource allocation framework of the Internet. The IANA allocates Internet number resources to Internet and parallels the existing INR distribution hierarchy. These INRs are distributed by the Internet Assigned Numbers Authority (IANA) to the Regional Internet Registries (RIRs), among others, as well as for special purposes [ RFC5736 Link: http://tools.ietf.org/html/rfc5736 ]. The RIRs, in turn, RFC 8190 Link: https://tools.ietf.org/html/rfc8190 ]. The RIRs manage the allocation of number resources to End Users, Internet Service Providers (ISPs) and others. (ISPs), and others.
In some regions, National Internet Registries (NIRs) are an additional tier in the INR distribution hierarchy, beneath the RIRs. Internet Service Providers (ISPs) and network subscribers then form further tiers below these registries.
This PKI encompasses several types of certificates (see IETF document draft-ietf-sidr-arch-xx Link: http://tools.ietf.org/wg/sidr/draft-ietf-sidr-arch/ RFC 6480 Link: https://tools.ietf.org/html/rfc6480 for more details):
CA certificates for each organisation distributing INRs and for the
each subscriberINR holderEnd-entity (EE) certificates for organisations
to useto validate digital signatures on RPKI-signed objects
In the future, the PKI may also include end-entity certificates in support of access control for the repository system, as described in Section 2.4In addition to the CP [RFCxxxx Link: #RFCxxxx ], [RFC 6484] Link: https://tools.ietf.org/html/rfc6484 , relevant information about general PKI concepts may be found in RFC5280, [RFC 5280 Link: https://tools.ietf.org/html/rfc5280 ], "Internet X.509 Public Key Infrastructure Certificate and Certificate Revocation List (CRL) Profile".

The name of this document is "RIPE NCC Certification Practice Statement for the Resource
PKI".1. 3. Public Key Infrastructure".1.3. PKI Participants
As per
Note: In1. 3. 1. Certification Authorities
1.3.1. Certification Authorities (CAs)
This CPS covers three five types of CAs for the RPKI: one Offline CA for the RIPE NCC, one Online CA All Resources CA (ACA) for the RIPE NCC, and one Production CA, a number of hosted member Hosted CAs, and a number of Delegated CAs, which are all equivalent and may be described as a single CA for the purpose of this document.
The Offline CA is the top level CA top-level CA for the RIPE NCC portion of RPKI, allowing the RIPE NCC to act as a Trust Anchor in the RPKI. The Online CA ACA allows the RIPE NCC to act as parent of the Production CA, which in turn acts as a parent CA to RIPE NCC Contributors. This two layer Members and the Delegated CA. This three-layer approach provides a secure revocation and recovery capability in case the Online CA ACA is compromised or becomes unavailable. The Thus, the Offline CA issues certificates only to instances of the Online CA. The CRLs issued by the Offline CA ACA, and the CRLs it issues are used to revoke only a certificate certificates issued to the Online CA. The Online ACA.The ACA issues certificates only to instances of the Production CA and the CRLs it issues are used to revoke only certificates issued to the Production CA. The Production CA is used to issue RPKI certificates to RIPE NCC Contributors, members, End Users, and , to whom Internet number resources have been distributed.
In addition addition, the RIPE NCC offers a hosted CA service to RIPE NCC Contributors. members and End Users. These CAs are designated "hosted member CAs". The hosted member CAs". Hosted CAs are highly automated, taking care of the major part of the operational burden for RIPE NCC Contributors Members who want to act as CAs in the RPKI.
See also section 1. 6 Link: #DefinitionsaandAcronyms section 1.6 for definitions and acronyms used in this document.
1. 3. 2. 1.3.2. Registration Authorities
There is no distinct Registration Authority (RA) for either the Offline CA or the Online CA, ACA, and the Production CA operating under this CPS. The former needs no distinct RA capability because it issues certificates only to the Online CA. The Online CA depends on the sign-on single sign-on (SSO) mechanism used by the LIR Portal to identify individuals authorised to make requests. One of the possible sign-on mechanisms is by using an X.509 client certificate issued by the RIPE NCC Business PKI (see section 3. 2. 6 3.2.6. for more details). The RIPE NCC already establishes a contractual relationship with each subscriber (RIPE NCC Contributor) member) and assumes responsibility for distributing and tracking the current allocation of address space and AS Numbers. Since the RIPE NCC operates the LIR Portal sign-on service and BPKI CA, no distinct RA is used.
1. 3. 3. 1.3.3. Subscribers
All RIPE NCC Contributors members and End Users can receive distributions of IP addresses and AS Numbers from the RIPE NCC Online CA and thus are subscribers in the PKI sense.
1. 3. 4. Relying parties
As per CP [RFCxxxx] Link: #RFCxxxx :
1.3.4. Relying parties
Entities or individuals that act in reliance on certificates or RPKI-signed objects issued under this PKI are relying parties. Relying parties may or may not be subscribers within this PKI. See section 1. 6 Link: #DefinitionsaandAcronyms (See section 1.6 for the definition of an RPKI-signed
object.1. 3. 5. object).1.3.5. Other participants
The RIPE NCC operates a repository that holds certificates, CRLs and other RPKI-signed objects, such as Route Origin Authorisation (ROA) objects.
1. 4. Certificate Usage
1. 4. 1. RIPE NCC Repository is regulated by the RIPE NCC Certification Repository Terms and Conditions Link: /manage-ips-and-asns/resource-management/rpki/legal/ripe-ncc-certification-repository-terms-and-conditions/ . 1.4. Certificate Usage
1.4.1. Appropriate certificate uses
The certificates issued under this hierarchy are for authorisation in support of validation of claims of current holdings of address space and/or AS Numbers. INRs. Additional uses, consistent with the basic goal cited above, are also permitted under [RFC 6484 Link: https://tools.ietf.org/html/rfc6484 ].
Some of the certificates that may be issued under this PKI could be used to support operation of this infrastructure (e.g. access control for the repository system as described in Section 2.4.) Such uses are also permitted under the RPKI certificate policy.

This document is reviewed
on behalf of the RIPE community by the Certification Authority Task Force (CA-TF). It is expected that the role of the CA-TF will be transferred to an appropriate RIPE Working Group when the RPKI becomes established as a RIPE NCC service.1. 5. 4. by qualified RIPE NCC staff, as well as by an external party during the review1.5.4. CPS approval procedures
A RIPE certification policy dealing with issues such as validity times, revocation, re-issuance and access to the services involved is currently being developed by the RIPE community. The implementation of the various CAs (Offline, Online and hosted member CAs) will reflect this policy.
This CPS is not subject to the RIPE Policy Development
Process. It provides a detailed outline of the implementation of the RPKI by the RIPE NCC. The CPS is publicly available and when necessary, additional reporting mechanisms, such as mailing lists or presentations at RIPE Meetings, are used to communicate the contents. When the RIPE NCC RPKI implementation is found to be inconsistent with applicable policies the RIPE NCC is committed to update the implementation and this CPS.1. 6. Process1.6.

Thus a tree structure of CAs can be created, often dubbed Public Key Infrastructure (PKI). The RIPE NCC operates three levels of CAs in the PKI hierarchy, covered in this CPS:
Offline CA The RIPE NCC Offline CA. This CA is kept offline when not in use for security reasons, and acts as the top level in the hierarchy. For the moment this CA is making itself available as a Trust Anchor as described in [draft-TA-version4]. In the future this CA may become subordinate to a top level single Trust Anchor CA that will issue certificates to all RIRs.
Online CA The RIPE NCC Online CA. This CA is used on a daily basis to issue certificates to subordinate hosted member CAs.
Hosted member CA A hosted member CA that is technically hosted by the RIPE NCC as a RIPE NCC service in the LIR Portal.
CP Certificate Policy for the Resource PKI (RPKI). See [RFCxxxx] Link: #RFCxxxx .
CP
Certificate Policy. A CP is a named set of rules that indicates the applicability of a certificate to a particular community and/or class of applications with common security requirements. The CP for the RPKI is [RFC 6484 Link: https://tools.ietf.org/html/rfc6484 ].
CPS Certification Practice Statement. A CPS is a document that specifies the practices that a Certification Authority employs in issuing certificates.
Distribution of INRs
Internet number resources (INRs) are distributed hierarchically. IANA distributes blocks of IP addresses and Autonomous System Numbers (ASNs) to the five Regional Internet Registries (RIRs). The RIRs distribute smaller address blocks and Autonomous System Numbers to organisations within their service regions, who in turn distribute IP addresses to their customers.
IANA
Internet Assigned Numbers Authority. IANA is responsible for global coordination of the Internet Protocol addressing systems and ASNs used for routing Internet traffic. IANA distributes INRs to RIRs.
INRs
Internet Number Resources. INRs are number values for three protocol parameter sets, namely:
- IP version 4 addresses (IPv4)
- IP version 6 addresses (IPv6)
- Identifiers used in Internet inter-domain routing, currently Border Gateway Protocol-4 ASNs
ISP Internet Service Provider. An ISP is an organisation managing and selling Internet services to other organisations.
LIR Local Internet Registry. This is an
NIR
National Internet Registry. NIRs manage the distribution of INRs for a portion of the geopolitical area covered by a Regional Internet Registry. NIRs form an optional second tier in the to INR distribution hierarchy.
RIR
Regional Internet Registry. An RIR is an organisation that manages the distribution of INRs for a geopolitical area.
RPKI-signed object
A digitally signed data object (other than a certificate or CRL) declared to be such an object by the Standards Track RFCs. An RPKI-signed object can be validated using certificates issued under this PKI. The content and format of these data constructs depend on the context in which validation of claims of current holdings of INRs take place. Examples of these objects are repository manifests [RFC 6486 Link: https://tools.ietf.org/html/rfc6486 ] and Route Origin Authorisations (ROAs) [RFC 6482 Link: https://tools.ietf.org/html/rfc6482 ].
CA
Certification Authority. A CA is an entity that issues digital certificates for use by other parties.
A CA may issue CA certificates to subordinate CAs. Thus, a tree structure of CAs can be created, often called Public Key Infrastructure (PKI). The RIPE NCC operates three levels of CAs in the PKI hierarchy covered in this CPS.
Offline CA
The RIPE NCC Offline CA. This CA is kept offline when not in use for security reasons, and acts
as the top level in the hierarchy. For the moment, this CA is making itself available as a Trust
Anchor as described in [RFC 8630 Link: https://tools.ietf.org/html/rfc8630 ].
Hosted CA
A hosted CA that is technically hosted by the RIPE NCC as a RIPE NCC service in the LIR portal.
Delegated CA
Delegated CA is technically hosted by the company behind the CA. The issuing, revocation of its certificate follows the RPKI certificate provisioning protocol, see [RFC 6492]. Link: https://datatracker.ietf.org/doc/rfc6492
All Resources CA (ACA)
An Online CA that contains all resources (e.g. 0/0) and is signed by the Trust Anchor. For more information, please see the NRO website Link: https://www.nro.net/regional-internet-registries-are-preparing-to-deploy-all-resources-rpki-service/ .
Production CA
This CA is used on a daily basis to issue certificates to subordinate Hosted CAs. It contains, in contrast to the ACA, only resources in the RIPE NCC region.
Local Internet Registry (LIR)
LIR Portal The public portal provided by the RIPE NCC to its members (LIRs) that allows them access to provides for its members to access various RIPE NCC services, including the hosted member CA service. The portal LIR Portal is also used to access the RIPE NCC Online CA by specific users, as described later in this CPS.
RIPE NCC Contributor A natural person or legal entity MemberA natural or a legal person that has entered into the RIPE NCC Standard Service Agreement (SSA) with the RIPE NCC.
RIR Regional Internet Registry. An RIR is an organisation that manages the distribution and registration of IP address and AS Numbers within a particular region of the world. At present, there are five RIRs: ARIN (North America), RIPE NCC (Europe, the Middle East and parts of Central Asia), APNIC (Asia-Pacific), LACNIC (Latin America and Caribbean) and AfriNIC (Africa).
End User
A natural or a legal person who is assigned provider independent (PI) resources from the RIPE NCC through a sponsoring agreement with a RIPE NCC member.
RP Relying Party as defined in section 1. 3. 4 Link: #Relyingparties .
TA Trust Anchor. The top CA certificate in the chain used for validation. Relying Parties choose which CA certificate they trust as being the top of the validation tree. Relying Parties may choose to trust more than one TA.

Online CA
The Online CA publishes subordinate certificates, CRLs and RPKI-signed objects under:
rsync://rpki.ripe.net/repository/33/36711f-25e1-4b5c-9748-e6c58bef82a5/1/
Hosted member CAs
The hosted member CAs publish subordinate signed objects in the repository that is hosted by the RIPE NCC:
rsync://rpki.ripe.net/repository
The exact URI of the publication point is unique per hosted member CA and CA. This can be found in the hosted member CA certificate as described in [res-certificate-profile] Link: #rescertificateprofile . [RFC 7318 Link: https://tools.ietf.org/html/rfc7318 ].
Note the repository structure is defined in
[RFCrepos] Link: #RFCrepos .2. 3. [RFC 6481 Link: https://tools.ietf.org/html/rfc6481 ].2.3. Time or Frequency of Publication
A certificate will be published within
24 hours after issuance.2. 4. eight hours of being issued (or deleted).
The RIPE NCC will publish its CRL prior to the next in the scheduled CRL previously issued by the CA.
Write access to the repositories is limited to the systems running the Offline CA, Online CA and hosted member ACA, Production CA, and hosted CAs.
3. Identification And Authentication3. 1. Naming
3. 1. 1. and Authentication3.1. Naming
3.1.1.
Types of names 3. 1. Naming
3. 1. 1.3.1. Naming
The Subject of each certificate issued by the RIPE NCC is identified by an X.500 Distinguished Name (DN). The distinguished name will consist of a single Common Name (CN) attribute with a value generated by the RIPE NCC. Optionally, the Serial Number attribute may be indicated along with the common name (to form a terminal relative distinguished name set), to distinguish between successive instances of certificates associated with the same entity.
For the Offline CA CA, the self-signed CA certificate is published as a Trust Anchor, as described in section 2. 2. Section 2.2. The subject is ‘CN=ripe-ncc-ta'. “CN=ripe-ncc-ta”.
For all other certificates controlled by the Offline CA, Online CA and hosted member CAs ACA, Production CA, and hosted CAs, the subject has the format CN=<pub key hash>, where the public key hash is a Base64 encoded form of the public key SHA-1 hash, as described in section 2.1 of
[RFC4387] Link: #RFC4387 .3. 1. 2. [RFC 4387 Link: https://tools.ietf.org/pdf/rfc6487.pdf ].3.1.2. Need for names to be meaningful
The Subject name in each subscriber certificate will be unique to the public key found
on the certificates.Note: The name of the holder of an address block or AS Number is intended to in the certificates.The Subject name should

Although subject Subject names in certificates issued by this registry are not should not be meaningful, and may appear "random,", anonymity is not a function of this PKI, and thus no PKI. No explicit support for this feature is provided.
3. 1. 4. 3.1.4. Rules for interpreting various name forms
None.
3. 1. 5. 3.1.5. Uniqueness of names
The RIPE NCC certifies Subject names that are unique among the certificates that it issues. Although it is desirable that Subject names be unique throughout the PKI (to facilitate certificate path discovery), uniqueness is not required and is not enforced through technical means. The RIPE NCC generates Subject names to minimise the chance that two entities in the RPKI will be assigned the same name. Specifically, the generated subject based on the public key hash, as described in 3.1.1, reduces hash (described in Section 3.1.1.) keeps the likelihood of accidental collisions to a negligible minimum.
3. 1. 6. 3.1.6. Recognition, authentication, and role of trademarks
Because Since the subject names are not intended to be meaningful, there is no provision the RIPE NCC makes no provision either to recognise or to authenticate trademarks, service marks, etc.
3. 2. 3.2. Initial Identity Validation
3. 2. 1. 3.2.1. Method to prove possession of private key
For the Offline CA, proof of possession of the private keys used for the self-signed certificate can be determined internally.
For the Online CA that acts as ACA, which acts as a subscriber to the Offline CA, and for the Production CA, which acts as a subscriber to the ACA, possession of the private keys is effected affected via the procedures used to generate and manage these keys. Specifically, the RIPE NCC uses a hardware security module (HSM) to generate the key pairs for each of these CAs and thus CAs. This assures that the private key is appropriately associated with the public key in the certificates issued by each of these CAs CAs.
For the hosted member CAs that act as subscribers to the Online Production CA, possession of the private keys is effected affected by the system. Note that the hosted member CAs are managed systems and operators do not access the keys directly. These CAs will contact the Online CA as needed Production CA as needed, via protocols internal to the RIPE NCC. These protocols also cover proof of possession of the private keys.
3. 2. 2.
The Delegated CA, which acts as a subscriber to the Production CA, holds its own key pair. The issuing or renewal of Certificates is performed via the provisioning protocol. See [RFC 6492 Link: https://tools.ietf.org/html/rfc6492 ].
The hosted Member CA is available only to RIPE NCC Contributors. The RIPE NCC has already established procedures to verify the identity of the RIPE NCC Contributors. These procedures are explained here:
However it should be noted that certificates identity of certificate holders. This is also reflected by the seemingly random subject names as described in 3.1.3.For hosted member CAs organisational identity of subscribers. However, certificates are issued to subscribers in a fashion that preserves the accuracy of INR registrations as represented in the RIPE NCC’s records.
The RIPE NCC has already established procedures to verify the identity of Certificate Holders. See section 3.2.3. below.
3. 2. 3. 3.2.3. Authentication of individual identity
The individuals
Certificates issued under this PKI do not attest to the individual identity of a subscriber. However, the RIPE NCC maintains contact information for each subscriber to support certificate renewal, re-key, and revocation.
Offline CA
For hosted member
Hosted CAs
the RIPE NCC Contributor's LIR Portal "admin" user. Admin users must set up users for their LIR and associate them with the ‘certification‘ role in order to grant individuals access to the certification section.
The admin user's identity can be (re-)established using the admin password reset procedure:
The reset procedure involves two halves of a code that are sent via two separate paths, email and fax, that need to be combined in order to reset the "admin" account's password.
For the Online CA, the same mechanism is used as described for hosted member CA users. It should be noted, however,For hosted End User CAs, individual identity is delegated to the LIR Portal account associated with the organisationobject referenced in the PI assignment.

The procedure to verify that an individual claiming to represent the subscriber is authorised to represent the subscriber for different CAs is as follows:
Access to the Online CA Production CA and ACA is restricted to RIPE NCC CA Operators using
the LIR Portal to log in and having an additional role enabled by the administrators of the single sign-on system (this role can not be set by others).Access
member CA is restricted to users of the LIR Portal that have the "certification" role enabled by the "admin" user for their registry.3. 2. 6. CA, see Section 3.2.3. above.3.2.6. Criteria for interoperation
The RPKI is not intended or designed to interoperate with any other
PKI at this stage.
The function of the Online CA will be extended in the future to interoperate with the other four RIRs and RIPE NCC Contributors operating their own CAs.
3. 3. Re-Key Requests3. 3. 1. Re-key Requests3.3.1.
Identification and authentication for routine re-key The procedure to ensure that a subscriber requesting routine re-key is the legitimate holder of the Certificate is as follows:
For the Offline CA and Online CA ACA, the same identification and authentication mechanisms apply as described in
section 3. 2. 3.For hosted member CAs
The key roll over rollover algorithm is described in
[RFCkeyroll].3. 3. 2. [RFC 6489 Link: https://tools.ietf.org/html/rfc6489 ].
The old key can be revoked as the final step in key rollover algorithm [RFCkeyroll] Link: #RFCkeyroll , after [RFC 6489 Link: https://tools.ietf.org/html/rfc6489 ], once a new key has been activated.
In our the RIPE NCC’s implementation, old keys are not automatically revoked after a routine re-key. Explicit revocation of old keys can be done by CA Operators of the Offline CA and the Online CA. CA Operators for the Online CA can also revoke old keys for specific hosted member hosted CAs. Identification and authentication for these roles
has been described in section 3. 2. 3 Link: #Authenticationofindiv .The RIPE NCC implementation may change following is described in Section 3.2.3.This may change after further
3. 4. 3.4. Identification and Authentication for Revocation Request
For hosted member CAs it should be CAs, the holder of the INRs can contact the RIPE NCC Registry Services Department to request the certificate revocation. It should be also noted that user actions in the interface may result in revocation of EE certificates used for objects (such as ROAs) that should be invalidated.
For non-hosted CAs, the holder can request the revocation in the user interface.

4.1.1. Who is able to submit a certificate application
Any RIPE NCC
Contributor may request a certificate.4. 1. 2. member or End User holding INRs distributed by the RIPE NCC may submit a certificate application to this CA. 4.1.2. Enrolment process and responsibilities
For the Offline CA a Developer CA, an Engineer can configure and initialise the CA on a server controlled by the RIPE NCC (see section 5. 2. 1 Section 5.2.1. for a description of the Developer Engineer role).
For the Online CA a Developer ACA and the Production CA, an Engineer can install and initialise the application. When this has been done done, a CA Operator can log in and initialise the Online ACA and the Production CA.
For hosted member CAs: RIPE NCC Contributors may use a hosted member CA hosted by the RIPE NCC as part of the RIPE NCC LIR portal. CAs, any RIPE NCC member or End User may choose to use a RIPE NCC-hosted Certification Authority or may choose to set up their own non-hosted CA. In order to activate the hosted member CA an "admin" CA, an "Admin" or “Regular” user must log in and grant the "certification" role to a normal user. to the LIR Portal. This user must then log in and ensure that a client certificate has been generated for them (or generate one if this is missing). The user that has the "certification" role will then be able to click through on a link labeled "Certification". This link labelled "RPKI Dashboard". This will take the user to a page where they must explicitly opt in to the hosted member CA service - they do CA service. The user does this by clicking "Yes, I want to activate my hosted member CA". After activation, a mostly automated hosted member an automated hosted CA will be created. Authentication and authorisation for further automated processes should be considered transitive from the moment that user
opted-in and activated the hosted member CA, as described here.4. 2. opts-in and activates the hosted CA.4.2. Certificate Application Processing
For hosted member CAs CAs, an initial CA certificate
is requested automatically by the system when the authorised user chooses to opt in to the service.4. 2. 1. should be requested by an authorised representative through the RPKI Dashboard in the LIR Portal.
The requester will be asked to choose the type of the CA as described in Section 4.1.2. and agree to the RIPE NCC Certification Service Terms and Conditions Link: /manage-ips-and-asns/resource-management/rpki/legal/ripe-ncc-certification-service-terms-and-conditions/ .
In the case of a hosted CA, the system will automatically create the certificate in the LIR Portal. The subscriber will need to accept the RIPE NCC Certification Service Terms and Conditions by clicking “I accept. Create my Certification Authority”. This way, the subscriber confirms that they have read, understood, and agree to be bound by these terms and conditions.
For non-hosted CA, the requester will need to upload the identity .xml file generated by their CA software.
See
section 3. 2. 3.4. 2. 2. Approval Section 3.2.3. for identification and authentication practice of certificate applicants.4.2.2. Approval or rejection of certificate applications
The online CA will issue certificates to hosted member CAs with a validity time CAs that are valid until to the end of the calendar year, plus a six months further six-month grace period to allow for renewal before the certificate expires.
All Provider Aggregatable (PA) resources registered to the RIPE NCC Contributor a RIPE NCC member at the time of issuance will be included in the certificate.
For hosted member CAs, the system will automatically request renewal of the CA certificate that lists all eligible resources when new resources are received by the RIPE NCC Contributor and/or a new validity time is applicable.

4.3.1. CA actions during certificate issuance
The Offline CA will produce a response message that includes all publishable certificates and other objects after the certificate has been issued. This message can be physically transferred to the Online CA, Production CA and the ACA, where it is published.
The Online CA and hosted member CAs Production CA and the ACA, as well as hosted CAs, make all subordinate certificates and objects available for publication. In practice, While the system will make a best effort to publish these materials as soon as possible, but as described in section 2. 3 Link: #TimeoorFFrequencyofPub , publication should happen
within no more than 24 hours of issuance.4. 3. 2. Notification to subscriber by the CA of issuance of certificate
Publication of a certificate in the repository operated by RIPE NCC is the means by which a subscriber is notified of certificate issuance. This procedure is employed by all CAs covered by this CPS.
4. 3. 3.4.3.2. Notification to subscriber by the CA of issuance of certificate
For RIPE NCC member and End User CAs, there is no active notification to a subscriber about certificate issuance. The approved and published certificate is visible in the RPKI Dashboard in the LIR Portal and in the RIPE NCC-hosted repository.

After the Certificate is issued, the subscriber can see the updated number of issued certificates under “Certified Resources” in the RPKI Dashboard in the LIR Portal.
Certificate acceptance by the subscriber is not part of the process.
Certificates will be published in the repository system within one business day eight hours of being issued by any of the CAs covered by this CPS.
4. 5. 4.4.3. Notification of certificate issuance by the CA to other entities
There are no entities other than the subscriber who are notified when a certificate is issued.
A summary of the use model for the IP Address and AS Number PKI RPKI is provided below.
4. 5. 1. 4.5.1. Subscriber private key and certificate usage
The hosted member CAs receive CA certificates from the Online CA. This means that these certificates could in principal be used to issue subordinate CA certificates. However, the hosted system does not provide this functionality. The hosted member CA certificates will only be used (by the system) to issue EE certificates used for RPKI-signed objects (such as ROAs) and manifests.
4. 5. 2. The private key associated with each of these certificates is used to sign subordinate (CA or EE) certificates and CRLs.4.5.2. Relying party public key and certificate usage
Reliance on a certificate must be reasonable under the circumstances. If the circumstances indicate a need for additional assurances, the relying party must obtain such assurances in order for such reliance to be deemed reasonable.
Before any act of reliance, relying parties MUST independently (1) verify independently:Verify that the certificate will be used for an appropriate purpose that is not prohibited or otherwise restricted by this CPS (see section 1. 5 Link: #CPSAdministration ), and (2) assess 1.4.)Assess the status of the certificate and all the CAs in the chain (terminating at the RIPE NCC Trust Anchor) that issued the that issued certificates relevant to the certificate in question. question (terminating at the RIPE NCC Trust Anchor accepted by the Relying arty). If any of the certificates in the certificate this chain have been revoked, revoked or have expired, the relying party is solely responsible for determining whether reliance on a digital signature to be verified by the certificate in question is acceptable. Any such reliance is made solely at the risk of the relying party.
If a relying party determines that use of the certificate is appropriate, the relying party must utilise appropriate software and/or hardware to perform digital signature verification as a condition of relying on the certificate. Moreover Moreover, the relying party MUST must validate the certificate in a manner consistent with the RPKI certificate profile [RFCyyyy] Link: #RFCyyyy , [RFC 6487 Link: https://tools.ietf.org/html/rfc6487 ], which specifies the extended validation algorithm for RPKI certificates.
4. 6. 4.6. Certificate Renewal
Note that the hosted member CAs do not issue CA certificates to subordinate CAs and there is no need for certificate renewal for EE certificates used for signed objects. However, hosted member CAs are mentioned a few times in this section as children of the
Online CA.4. 6. 1. Circumstance Production CA and the ACA.4.6.1. Circumstances for certificate renewal
For hosted member CAs: When new Internet number resources are associated with a RIPE NCC Contributor or a new validity time is applicable (see section 4. 2. 2 Link: #Approvalofcertificate ) a A certificate will be
renewed.Note that in case Internet number resources renewed for hosted CAs when new INRs are associated with a RIPE NCC member or End User, or a new validity period is applied (see Section 4.2.2).Note that if INRs
section 4. 9 Link: #CertificateRevocationaan .4. 6. 2. Section 4.9.4.6.2. Who may request renewal
For hosted
member CAs, requests for renewal are fully automated.For the Online CA, RIPE NCC staff with the Online CA Administrator role CAs, the renewal process is fully automated, which means that the subscriber cannot initiate renewal.For the Production CA and the ACA, a RIPE NCC Engineer
For the Offline CA, Internet number resources may have to be added to the self-signed certificate. RIPE NCC staff with the appropriate role A RIPE NCC Engineer may perform this action.
4. 6. 3. 4.6.3 Processing certificate renewal requests
The same stipulations listed in section 4. 2. 2 Link: #Approvalofcertificate apply here.
4. 6. 4.See 4.6.1.
For hosted CAs, the system will automatically request renewal of the CA certificate that lists all eligible INRs when new resources are received by a RIPE NCC member or End User, or a new validity period is applicable.

requested, based on:Knowledge or suspicion of
compromise or loss of the associated private key, orrequired, based on:Confirmed/suspectedkeyExpiration of the cryptographic lifetime of the associated key pair
If a certificate is revoked to replace the resource extensions (see [res-certificate-profile] Link: #rescertificateprofile , RFC 3779 Link: https://tools.ietf.org/pdf/rfc3779.pdf ), the replacement certificate will incorporate the same public key, not a new key, unless the subscriber requests a re-key at the same time. key (not a new key). If the re-key is based on a suspected compromise, then the previous certificate will be revoked.
Section 5.6 of the Certificate Policy [RFC 6484 Link: https://tools.ietf.org/html/rfc6484 ] notes that when a CA signs a certificate, the signing key should have a validity period that exceeds the validity period which exceeds that of the certificate. This places additional constraints on when a CA should request a re-key.

4. 9. 1. 4.9.1. Circumstances for revocation
Certificates can must be revoked for several reasons:
A signed object needs to be invalidated
One or more listed Internet number resources
INRsare no longer associated with the RIPE NCCContributorAs the last steps
member or End UserAs a last step when doing a planned re-key (clean up) As the last steps
a last stepwhen doing an unplanned re-key because a loss or compromise of the old key has come to light
4. 9. 2. The RIPE NCC member violates the RIPE NCC Certification Service Terms and Conditions
A certificate may be revoked if a signed object needs to be invalidated.
For the hosted member Hosted and Delegated CAs, revocation of their CA certificate can be performed by RIPE NCC staff on request automatically via the RPKI Dashboard in the LIR Portal, or when RIPE NCC staff have reason to believe the keys are compromised. In the latter case this will have been compromised. In this latter case, this would always be performed as the final step of an emergency key rollover for the hosted member CA. CA.
For Delegated CAs, the revocation request can be done via the RPKI Dashboard in the LIR Portal.
For the Online CA, Production CA and the ACA, the RIPE NCC may manually request revocation of the old CA certificate as soon as a key rollover has been performed. Related events, most notably the revocation of the EE certificates used for manifests, are managed by the system.
4. 9. 3. 4.9.3. Procedure for revocation request
When one or more of the Internet number resources INRs listed in a certificate are no longer associated with a RIPE NCC Contributor, member or End User, the Online CA will:
Re-issue a new certificate, minus the lost Internet number resources, but maintaining
certificate that retainsall other properties(minus the affected INRs)Publish the new certificate using the same publication point as before, thus replacing the old certificate
Revoke any non-expired certificates held by the hosted member CA that list the lost Internet number resources,
affected INRs,thus invalidating any signed objects (such as ROAs) that refer to theseInternet number resources.4. 9. 4.
resourcesFor Delegated CAs, a new certificate not be issued automatically once the revocation request has been completed. This will have to be requested again via the LIR Portal.4.9.4.
Any party that is able to identify the or operators who can identify a need for revocation that is not already handled by the system and operators is are expected to notify the RIPE NCC
within one business day.4. 9. 5. as soon as possible.4.9.5. Time within which CA must process the revocation request
The RIPE NCC will process a revocation request within one business day eight hours of receipt and validation of the request.
4. 9. 6. 4.9.6. Revocation checking requirement for relying parties
As per the CP, [RFC 6484 Link: https://tools.ietf.org/html/rfc6484 ], whenever a relying party validates a certificate, it is responsible for acquiring and checking the most recent, scheduled CRL from the issuer of the
certificate, whenever that relying party validates a certificate.4. 9. 7. certificate4.9.7. CRL issuance frequency
Each CRL will carry a nextScheduledUpdate value contains a “Next Update” value, and a new CRL will be published at or before that time. The RIPE NCC will set the nextScheduledUpdate “Next Update” value when it issues a CRL to signal when the next scheduled CRL will be issued. The CAs covered by this CPS use different values:
Offline CA: 3 months from the moment of issuance
Online CA: 24 hours from the moment of issuance
Hosted member CAs: 24 hours from the moment of issuance
ACA
24 hours from the moment of issuance
As a matter of good operational sense, practice, all CAs covered by this CPS will strive aim to republish and re-issue a new CRL before the next scheduled update value in value, to allow time to deal with any operational problems.
It should be noted that the values listed here may be used by relying parties to determine the need to fetch an updated CRL.
In particular this means that a possible revocation by the Offline CA may go unnoticed for three months - this should not be a problem since the production keys are protected by an HSM. A revoked ROA for a hosted member CA may not be noticed for 24 hours. The values here should be regarded as a compromise between various aspects, including the operational burden of re-signing (for Offline CA), time needed to be able to do an emergency restore, efficiency of caching in the global RPKI, propagation time of revocation in the global RPKI.4. 9. 8. 4.9.8.

Independent contractors and consultants may be part of the development team, but never constituting more than 50% of the total team.
5. 3. 8.Training for staff assigned to a trusted CA role is primarily via mentoring. An internal wiki is maintained by RIPE NCC staff as a further training aid.
5. 4. 5.4. Audit Logging Procedures
5. 4. 1.
Below is the description of how RIPE NCC implements audit logging.
For the Offline CA CA, no audit logging is implemented.
Audit records are generated for operations performed by the CA operators for the Online CA and hosted member CAs. Audit Operators for the Production CA, ACA and hosted CAs. These records include the date, time, responsible user and summary content data relating to the event. Records are stored in a database and are visible through the user interface.
The physical access control system separately maintains maintains separate logs for access to the areas housing sensitive CA equipment.
5. 4. 2.
Auditable events include, but are not limited to, the following:
Access to CA computing equipment (e.g. log-in, log-out)Messages received requesting CA actions (e.g. certificate requests, certificate revocation requests, compromise notifications)Certificate creation, modification, revocation, or renewal actionsPosting of any material to a repositoryAny attempts to change or delete audit dataKey generationSoftware and/or configuration updates to the CA
Logs will be analysed reviewed during general audits or after a suspected incident.
5. 4. 3. 5.4.3. Retention period for audit log
Audit records for the Online CA and hosted member CAs Production CA and the ACA, as well as hosted CAs, are included in the nightly database back-up and retained off-site for a minimum of two years.

5.6. Key Changeover
The Offline CA currently acts as a Trust Anchor.
An emergency key rollover has been practiced for the current set-up.The Online CA
The hosted member CAs perform an automated re-key using the algorithm described in[RFCkeyroll] Link: #RFCkeyroll .This happens whenever a key has been in use for five years.
5. 6.5.7. Compromise and Disaster Recovery
In the event of a key-pair compromise, a key-rollover can be performed on demand for Production CA, ACA and Hosted CA.
As part of disaster recovery, backups are used.
For the Trust Anchor, in case of key-pair compromise a key-rollover will be performed and a new Trust Anchor Locator (TAL) will be published.
The RIPE NCC has been granted sole authority by the Internet Assigned Numbers Authority (IANA) to manage the allocation of IP address space and AS Number resources in the RIPE NCC Numbers in its service region, which includes Europe, the Middle East and parts of Central Asia. The RIPE NCC has established the RPKI for its region consistent with this authority. There are no provisions for termination and transition of the CA function to another entity.
6. Technical Security Controls
This section describes the security controls used by the RIPE NCC.
6. 1. 6.1. Key Pair Generation and Installation
6. 1. 1. 6.1.1. Key pair generation
For the RIPE NCC RPKI and hosted member CAs operated by the RIPE NCC, key pairs are generated using a hardware cryptographic module. The module used for this purpose is certified as complying with FIPS 140-2 level 3. The hardware cryptographic module employed for this process is
the nCipher nShield9000e.6. 1. 2. nShield Connect 6000.6.1.2. Private key delivery to subscriber
Private keys can not cannot be extracted from the HSM in unencrypted form. The Offline CA and Online CA, the ACA and the production CA only require the public key from their subscribers. The hosted member Hosted CAs have no subscribers.
6. 1. 3. 6.1.3. Public key delivery to certificate issuer
For the Offline CA, a custom mechanism has been developed to transfer transfer of certificate sign requests and/or revocation requests that include the Online CA public key hash. Since the Offline CA server is not connected to a network, the transfer is ACA public key hash are done using XML files on a USB
stick (a.k.a. sneaker net).The hosted member CAs and Online CA are stick, because the Offline CA server is not connected to a network.The hosted CA, the ACA, and the production CA are all
6. 1. 4. 6.1.4. CA public key delivery to relying parties
For the Online ACA, the production CA and hosted member CAs, CA, public keys are included in CA and EE certificates issued by these CAs. The keys are delivered to relying parties by publication of the CA certificates and signed objects that include EE certificates (ROAs and manifests) to in the repository.
The Offline CA is intended to be used as a Trust Anchor by relying parties. Its The Trust Anchor Locator [RFCtrustanchor] Link: #RFCtrustanchor [RFC 6490 Link: https://tools.ietf.org/html/rfc6490 ] is described in section 2. 2 Link: #PublicationofCertificati . Section 2.2. The RIPE NCC will publish this Trust Anchor Locator at:
http://www.ripe.net/certification/validation Link: http://www.ripe.net/certification/validation
https://www.ripe.net/manage-ips-and-asns/resource-management/certification/ripe-ncc-rpki-trust-anchor-structure Link: /manage-ips-and-asns/resource-management/rpki/ripe-ncc-rpki-trust-anchor-structure/
It may also publish this via other mechanisms, such as printed material, RIPE Meeting presentations or
in Member Updates.6. 1. 5. Key sizes
As per [RFCalgokeysize], the CAs covered by this CPS use a 2048-bit RSA key for all keys, including the keys used for EE certificates.
6. 1. 6.6.1.5. Key sizes
The key sizes used in this PKI are as specified in [RFC 7935 Link: https://tools.ietf.org/html/rfc7935 ].
The public key algorithms and parameters used in this PKI are as specified in [RFC 7935 Link: https://tools.ietf.org/html/rfc7935 ].
The nCipher HSMs used by the CAs covered by this CPS were certified as complying with FIPS 140-2 level 3. Though the details of the key generation implementation used by these modules are not known by the RIPE NCC, the RIPE NCC trusts that this certification implies that key generation and quality checking by the modules is sufficiently safe.
6. 1. 7. 6.1.7. Key usage purposes (as per X.509 v3 key usage field)
The key usage extension bit values employed in RPKI certificates are specified in [RFC 6487 Link: https://tools.ietf.org/html/rfc6487 ].The key usage extension bit values are consistent with [RFC5280] Link: #RFC5280 . [RFC 6818 Link: https://tools.ietf.org/html/rfc6818 ]. For the RIPE NCC RPKI CA certificates, the keyCertSign and cRLSign bits are set TRUE. All other bits (including digitalSignature) are set FALSE, and the extension is marked critical.
6. 2. 6.2. Private Key Protection and Cryptographic Module Engineering Controls
6. 2. 1. 6.2.1. Cryptographic module standards and controls
The Offline CA is operated under FIPS 140-2 level 3, requiring three out of ten operator keys to be presented for key pair generation and signing operations.
The Online CA and hosted member ACA, the production CA, and hosted CAs employ a cryptographic module evaluated under FIPS 140-2 level 3 [FIPS]. [FIPS Link: https://nvlpubs.nist.gov/nistpubs/FIPS/NIST.FIPS.140-2.pdf ]. However, because these systems need to be running 24/7 and need to be able to perform key generation and signing operations without human intervention, they are operated under FIPS 140-2 level 2 to allow unattended operation.
6. 2. 2. 6.2.2. Private key (n out of m) multi-person control
As described in section 6. 2. 1 Link: #Cryptographicmodulest , Section 6.2.1, three out of ten CA Operators are required to operate the Offline CA.
For the Online ACA, Production CA and hosted member CAs CA, no multi-person control is used during normal operation.
6. 2. 3. 6.2.3. Private key escrow
No private key escrow procedures are required for this PKI.
6. 2. 4. 6.2.4. Private key backup
For all CAs covered by this CPS, the private keys are stored on disk by in the database that feeds the HSM using Advanced Encryption Standard (AES) encryption with a key that is protected by a 3-out-of-5 three-out-of-five Administrative Card Set.
For the Offline CA, the files containing the encrypted private key
and other necessary information are copied to fileshare that is duplicated between the Nikhef and Telecity2 data centres after every operation. These files are backed up off-site on a nightly basis to a remote site located in Ede, the Netherlands, 70 km from Amsterdam.
For the Online CA and hosted member CAs, all encrypted private keys and other necessary information are stored on a fileshare that is duplicated between the Nikhef and Telecity2 data centers after every operation. These files are backed up off-site on a nightly basis to a remote site located in Ede, the Netherlands, 70 km from Amsterdam.

The encrypted private keys and other information described in section 6. 2. 4 Section 6.2.4. may be restored to another HSM. In order to do this, a system administrator must have access to a quorum of the Administrative Card Set (ACS); in this case three out of five three-out-of-five cards are needed.
Also note that this mechanism allows multiple HSMs to share the same internal key and encrypted managed keys stored on a network file system. This allows for the load balancing and fail-over set-up that is used for the
Online CA and member CAs.6. 2. 7. ACA, the production CA, and hosted CAs.6.2.7. Private key storage on cryptographic module
The private keys for all CAs covered by this CPS may be temporarily stored inside in the cryptographic module and will be protected from unauthorised use in accordance with the FIPS 140-2 [FIPS 140-2 Link: https://nvlpubs.nist.gov/nistpubs/FIPS/NIST.FIPS.140-2.pdf ] requirements applicable to the module.
Long term storage is done by storing the keys to disk in on a disk in an encrypted form, as described above.
6. 2. 8. 6.2.8. Method of activating private key
For the Offline CA, activating the keys requires that three out of five three-out-of-five Operator cards are presented by individual senior staff, as described in

The Offline CA keys are de-activated as soon as processing is finished. Subsequent operation will require re-activation as described above. In addition addition, the server is physically turned off when not in use. As soon as processing is done, the server is backed up and is shut down again.
The cryptographic modules for the RIPE NCC RPKI CA and hosted member ACA, Production CA, and hosted CAs will operate in an unattended mode, on a 24/7 basis.
6. 2. 10. 6.2.10. Method of destroying private key
Keys are not stored long-term inside the hardware security modules used by the CAs covered by this CPS. The HSMs store the keys on disk in encrypted form. When keys Keys are deleted when they are no longer in use they are deleted from disk. use. Since they were encrypted in the first place, no additional action is taken to zero the bytes or purge them from long term back-up.

6. 5. 6.5. Computer Security Controls
6. 5. 1. Specific computer security technical requirement
The Offline CA is kept offline when not in use. It is only switched on when in use and is never connected to any network. All data (requests, responses, backups) are transferred using otherwise empty USB sticks.
The Online CA and hosted member ACA, Production CA, and hosted CAs are operated on machines in the RIPE NCC internal service VLAN. The user interface is made available through a firewall that load balances requests to two different back-end proxy servers.
These will delegate requests for the "certification" section only to the back-end machines.6. 5. 2. Computer security rating [OMITTED]
6. 6. 6.6. Life Cycle Technical Controls
6. 6. 1. 6.6.1. System development controls
The software for all CAs covered by this CPS was developed in-house by the RIPE NCC, working together with external consultants. The RIPE NCC software development follows an "agile" methodology that includes test-driven development. Unit test coverage of at least 75% Unit test and succeeding functional tests were required for all components. All software is developed and maintained under a revision control system (subversion) (git) and releases are tagged. Continuous integration is triggered for each commit and each release and release, which ensures that any possible broken tests come to light before a release is made final. Code is subject to a code review during development. The RIPE NCC software development Software Development department uses bug and issue tracking software for all software development. Prior to deployment to the production service, code is versioned and deployed to a standalone platform for integration tests. The same packages used for these integration tests are then deployed to the production service, provided that no problems
were found.6. 6. 2. are found.6.6.2. Security management controls
The RIPE NCC uses the same access policy for the servers used to run the Offline CA and the Online and member CAs: CA, the ACA, the Production CA, and hosted CAs; only staff from the responsible departments have SSH access. SSH access is limited to the RIPE NCC office and VPN networks. Access to the systems is logged.
It In addition, it should be noted that in addition, the Offline CA server is physically switched off when not in use.
6. 6. 3. 6.6.3. Life cycle security controls
See section 6. 6. 1 Link: #Systemdevelopmentcont for Section 6.6.1 contains a description of the software life cycle, including testing prior to release. Deployment of new software releases is scheduled, with planned back-out, on demand, with planned roll-back, and post-deployment testing of service.
Host operating systems are maintained to current patch levels, and CERT (Computer Emergency Response Team) and other security advisories are tracked for relevant vulnerabilities.
Hosts and network infrastructure are physically maintained and replaced in a duty cycle averaging four years. Onsite maintenance contracts cover normal business hours support for this hardware.
6. 7. 6.7. Network Security Controls
The vLAN used for the servers that host the CAs covered by this CPS is protected by router Access Control Lists (ACLs) and/or by firewall rules. This applies both to incoming and outgoing traffic from/to other vLANs, and the same applies for the Internet at large. We do not currently have a dedicated vLAN for these servers, though we plan to look into this in the near future.
Sensitive data is protected by at least one of TLS or SSL with client and server certificates, and with SSH version 2 with 1024-bit keys, or better.
Extra care is taken for private data: PGP encryption is mandatory.
