Best Current Practice [Page 7] RFC 7382 Template CPS for the RPKI April 2015 Preface This RFC contains text intended for use as a template as designated below by the markers and . Such Template Text is subject to the provisions of Section 9(b) of the Trust Legal Provisions. This document contains a template to be used for creating a Certification Practice Statement (CPS) for an organization that is part of the Resource Public Key Infrastructure (RPKI). (Throughout this document, the term "organization" is used broadly, e.g., the entity in question might be a business unit of a larger organization.) There is no expectation that a CPS will be published as an RFC. An organization will publish the CPS in a manner appropriate for access by the users of the RPKI, e.g., on the organization's web site. As a best current practice, organizations are expected to use this template instead of creating one from scratch. This template contains both text that SHOULD appear in all Certification Practice Statements and places for text specific to the organization in question (indicated by ). The user of this document should: 1. Extract the text between the and delimiters. 2. Replace the instructions between the angle brackets with the required information. This document has been generated to complement the Certificate Policy (CP) for the RPKI [RFC6484]. Like RFC 6484, it is based on the template specified in RFC 3647 [RFC3647]. A number of sections contained in the template were omitted from this CPS because they did not apply to this PKI. However, we have retained the section numbering scheme employed in that RFC to facilitate comparison with the section numbering scheme employed in that RFC and in RFC 6484. Conventions Used in This Document: The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119]. Kent, et al. Best Current Practice [Page 8] RFC 7382 Template CPS for the RPKI April 2015 Certification Practice Statement for the Resource Public Key Infrastructure (RPKI)" with date, author, etc.> 1. Introduction This document is the Certification Practice Statement (CPS) of . It describes the practices employed by the Certification Authority (CA) in the Resource Public Key Infrastructure (RPKI). These practices are defined in accordance with the requirements of the Certificate Policy (CP) [RFC6484] for the RPKI. The RPKI is designed to support validation of claims by current holders of Internet Number Resources (INRs) (Section 1.6) in accordance with the records of the organizations that act as CAs in this PKI. The ability to verify such claims is essential to ensuring the unique, unambiguous distribution of these resources. This PKI parallels the existing INR distribution hierarchy. These resources are distributed by the Internet Assigned Numbers Authority (IANA) to the Regional Internet Registries (RIRs). In some regions, National Internet Registries (NIRs) form a tier of the hierarchy below the RIRs for INR distribution. Internet Service Providers (ISPs) and network subscribers form additional tiers below registries. Conventions Used in This Document: The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119]. Kent, et al. Best Current Practice [Page 9] RFC 7382 Template CPS for the RPKI April 2015 1.1. Overview This CPS describes: o Participants o Publication of the certificates and Certificate Revocation Lists (CRLs) o How certificates are issued, managed, re-keyed, renewed, and revoked o Facility management (physical security, personnel, audit, etc.) o Key management o Audit procedures o Business and legal issues This PKI encompasses several types of certificates (see [RFC6480] for more details): o CA certificates for each organization distributing INRs and for each subscriber INR holder. o End-entity (EE) certificates for organizations to use to validate digital signatures on RPKI-signed objects (see definition in Section 1.6). o In the future, the PKI also may include end-entity certificates in support of access control for the repository system as described in Section 2.4. 1.2. Document Name and Identification The name of this document is " Certification Practice Statement for the Resource Public Key Infrastructure (RPKI)". Kent, et al. Best Current Practice [Page 10] RFC 7382 Template CPS for the RPKI April 2015 1.3. PKI Participants Note that in a PKI the term "subscriber" refers to an individual or organization that is a subject of a certificate issued by a CA. The term is used in this fashion throughout this document, without qualification, and should not be confused with the networking use of the term to refer to an individual or organization that receives service from an ISP. In such cases, the term "network subscriber" will be used. Also note that, for brevity, this document always refers to PKI participants as organizations or entities, even though some of them are individuals. 1.3.1. Certification Authorities portion of the RPKI. It provides a secure revocation and recovery capability in case the production CA is compromised or becomes unavailable. Thus, the offline CA 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 members, to whom INRs have been distributed.> 1.3.2. Registration Authorities 1.3.3. Subscribers Organizations receiving INR allocations from this CA are subscribers in the RPKI. 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 for the definition of an RPKI-signed object.) Kent, et al. Best Current Practice [Page 11] RFC 7382 Template CPS for the RPKI April 2015 1.3.5. Other Participants 1.4. Certificate Usage 1.4.1. Appropriate Certificate Uses The certificates issued under this hierarchy are for authorization in support of validation of claims of current holdings of INRs. Additional uses of the certificates, consistent with the basic goal cited above, are also permitted under RFC 6484. 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 also are permitted under the RPKI certificate policy. 1.4.2. Prohibited Certificate Uses Any uses other than those described in Section 1.4.1 are prohibited. 1.5. Policy Administration 1.5.1. Organization Administering the Document This CPS is administered by . 1.5.2. Contact Person 1.5.3. Person Determining CPS Suitability for the Policy Not applicable. Each organization issuing a certificate in this PKI is attesting to the distribution of INRs to the holder of the private key corresponding to the public key in the certificate. The issuing organizations are the same organizations as the ones that perform the distribution; hence, they are authoritative with respect to the accuracy of this binding. Kent, et al. Best Current Practice [Page 12] RFC 7382 Template CPS for the RPKI April 2015 1.5.4. CPS Approval Procedures Not applicable. Each organization issuing a certificate in this PKI is attesting to the distribution of INRs to the holder of the private key corresponding to the public key in the certificate. The issuing organizations are the same organizations as the ones that perform the distribution; hence, they are authoritative with respect to the accuracy of this binding. 1.6. Definitions and Acronyms BPKI Business PKI. A BPKI is an optional additional PKI used by an organization to identify members to whom RPKI certificates can be issued. If a BPKI is employed by a CA, it may have its own CP, separate from the RPKI CP. 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 [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 A process of distribution of the INRs along the respective number hierarchy. IANA distributes blocks of IP addresses and Autonomous System Numbers (ASNs) to the five Regional Internet Registries (RIRs). RIRs distribute smaller address blocks and Autonomous System Numbers to organizations 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: o IP version 4 addresses, o IP version 6 addresses, and o Identifiers used in Internet inter-domain routing, currently Border Gateway Protocol-4 ASNs. Kent, et al. Best Current Practice [Page 13] RFC 7382 Template CPS for the RPKI April 2015 ISP Internet Service Provider. An ISP is an organization managing and selling Internet services to other organizations. NIR National Internet Registry. An NIR is an organization that manages 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 tree scheme used to manage INR distribution. RIR Regional Internet Registry. An RIR is an organization that manages the distribution of INRs for a geopolitical area. RPKI-signed object An RPKI-signed object is a digitally signed data object (other than a certificate or CRL) declared to be such an object by a Standards Track RFC. 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 takes place. Examples of these objects are repository manifests [RFC6486] and Route Origin Authorizations (ROAs) [RFC6482]. 2. Publication and Repository Responsibilities 2.1. Repositories As per the CP, certificates, CRLs, and RPKI-signed objects MUST be made available for downloading by all relying parties, to enable them to validate this data. The RPKI CA will publish certificates, CRLs, and RPKI-signed objects via a repository that is accessible via at . This repository will conform to the structure described in [RFC6481]. 2.2. Publication of Certification Information will publish certificates, CRLs, and RPKI-signed objects issued by it to a repository that operates as part of a worldwide distributed system of RPKI repositories. 2.3. Time or Frequency of Publication The CA will publish its CRL prior to the nextUpdate value in the scheduled CRL previously issued by the CA. 2.4. Access Controls on Repositories 3. Identification and Authentication 3.1. Naming 3.1.1. Types of Names The subject of each certificate issued by this organization 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 . Optionally, the serialNumber attribute may be included along with the common name (to form a terminal relative distinguished name set), to distinguish among successive instances of certificates associated with the same entity. 3.1.2. Need for Names to Be Meaningful The Subject name in each certificate SHOULD NOT be "meaningful", in the conventional, human-readable sense. The rationale here is that these certificates are used for authorization in support of applications that make use of attestations of INR holdings. They are not used to identify subjects. 3.1.3. Anonymity or Pseudonymity of Subscribers Although Subject names in certificates issued by this organization SHOULD NOT be meaningful and may appear "random", anonymity is not a function of this PKI; thus, no explicit support for this feature is provided. 3.1.4. Rules for Interpreting Various Name Forms None Kent, et al. Best Current Practice [Page 15] RFC 7382 Template CPS for the RPKI April 2015 3.1.5. Uniqueness of Names certifies Subject names that are unique among the certificates that it issues. Although it is desirable that these Subject names be unique throughout the PKI, to facilitate certificate path discovery, such uniqueness is not required, nor is it enforced through technical means. generates Subject names to minimize the chances that two entities in the RPKI will be assigned the same name. Specifically, . 3.1.6. Recognition, Authentication, and Role of Trademarks Because the Subject names are not intended to be meaningful, makes no provision either to recognize or to authenticate trademarks, service marks, etc. 3.2. Initial Identity Validation 3.2.1. Method to Prove Possession of Private Key 3.2.2. Authentication of Organization Identity Certificates issued under this PKI do not attest to the organizational identity of subscribers. However, certificates are issued to subscribers in a fashion that preserves the accuracy of distributions of INRs as represented in records. subscriber database that maintains the INR distribution records. The certificate request could be matched against the database record for the subscriber in question, and an RPKI certificate would be issued only if the INRs requested were a subset of those held by the subscriber. The specific procedures employed for this purpose should be commensurate with any you already employ in the maintenance of INR distribution.> Kent, et al. Best Current Practice [Page 16] RFC 7382 Template CPS for the RPKI April 2015 3.2.3. Authentication of Individual Identity Certificates issued under this PKI do not attest to the individual identity of a subscriber. However, maintains contact information for each subscriber in support of certificate renewal, re-key, and revocation. BPKI (see Section 3.2.6) issues certificates that MUST be used to identify individuals who represent subscribers." The procedures should be commensurate with those you already employ in authenticating individuals as representatives for INR holders. Note that this authentication is solely for use by you in dealing with the organizations to which you distribute (or sub-distribute) INRs and thus MUST NOT be relied upon outside of this CA/subscriber relationship.> 3.2.4. Non-verified Subscriber Information No non-verified subscriber data is included in certificates issued under this certificate policy except for Subject Information Access (SIA) extensions [RFC6487]. 3.2.5. Validation of Authority 3.2.6. Criteria for Interoperation The RPKI is neither intended nor designed to interoperate with any other PKI. Kent, et al.

Notification of Certificate Issuance by the CA to Other Entities 4.5. Key Pair and Certificate Usage A summary of the use model for the RPKI is provided below. 4.5.1. Subscriber Private Key and Certificate Usage The certificates issued by to subordinate INR holders are CA certificates. The private key associated with each of these certificates is used to sign subordinate (CA or EE) certificates and CRLs. Kent, et al. Best Current Practice [Page 20] RFC 7382 Template CPS for the RPKI April 2015 4.5.2. Relying Party Public Key and Certificate Usage The primary relying parties in this PKI are organizations that use RPKI EE certificates to verify RPKI-signed objects. Relying parties are referred to Section 4.5.2 of [RFC6484] for additional guidance with respect to acts of reliance on RPKI certificates. 4.6. Certificate Renewal 4.6.1. Circumstance for Certificate Renewal As per RFC 6484, a certificate will be processed for renewal based on its expiration date or a renewal request from the certificate Subject. The request may be implicit, a side effect of renewing a resource holding agreement, or explicit. If initiates the renewal process based on the certificate expiration date, then will notify the subscriber . The validity interval of the new (renewed) certificate will overlap that of the previous certificate by , to ensure uninterrupted coverage. Certificate renewal will incorporate the same public key as the previous certificate, unless the private key has been reported as compromised (see Section 4.9.1). If a new key pair is being used, the stipulations of Section 4.7 will apply. 4.6.2. Who May Request Renewal The subscriber or may initiate the renewal process. Kent, et al.

Notification of Certificate Issuance by the CA to Other Entities See Section 4.4.3. 4.7. Certificate Re-key 4.7.1. Circumstance for Certificate Re-key As per RFC 6484, re-key of a certificate will be performed only when required, based on: 1. knowledge or suspicion of compromise or loss of the associated private key, or 2. the expiration of the cryptographic lifetime of the associated key pair If a certificate is revoked to replace the RFC 3779 extensions, the replacement certificate will incorporate the same public key, not a new key. If the re-key is based on a suspected compromise, then the previous certificate will be revoked. Kent, et al. Best Current Practice [Page 22] RFC 7382 Template CPS for the RPKI April 2015 4.7.2. Who May Request Certification of a New Public Key Only the holder of a certificate may request a re-key. In addition, may initiate a re-key based on a verified compromise report. BPKI.

Publication of the Re-keyed Certificate by the CA 4.7.7. Notification of Certificate Issuance by the CA to Other Entities See Section 4.4.3. 4.8. Certificate Modification 4.8.1. Circumstance for Certificate Modification As per RFC 6484, modification of a certificate occurs to implement changes to the RFC 3779 extension values or the SIA extension in a certificate. A subscriber can request a certificate modification when this information in a currently valid certificate has changed, as a result of changes in the INR holdings of the subscriber, or as a result of change of the repository publication point data. Kent, et al. Best Current Practice [Page 23] RFC 7382 Template CPS for the RPKI April 2015 If a subscriber is to receive a distribution of INRs in addition to a current distribution, and if the subscriber does not request that a new certificate be issued containing only these additional INRs, then this is accomplished through a certificate modification. When a certificate modification is approved, a new certificate is issued. The new certificate will contain the same public key and the same expiration date as the original certificate, but with the incidental information corrected and/or the INR distribution expanded. When previously distributed INRs are to be removed from a certificate, then the old certificate will be revoked and a new certificate (reflecting the new distribution) issued. 4.8.2. Who May Request Certificate Modification The subscriber or may initiate the certificate modification process. 4.8.3. Processing Certificate Modification Requests 4.8.4. Notification of Modified Certificate Issuance to Subscriber 4.8.5. Conduct Constituting Acceptance of Modified Certificate When a modified certificate is issued, will publish it to the repository and notify the subscriber. See Section 4.4.1. 4.8.6. Publication of the Modified Certificate by the CA 4.8.7. Notification of Certificate Issuance by the CA to Other Entities See Section 4.4.3. Kent, et al. Best Current Practice [Page 24] RFC 7382 Template CPS for the RPKI April 2015 4.9. Certificate Revocation and Suspension 4.9.1. Circumstances for Revocation As per RFC 6484, certificates can be revoked for several reasons. Either or the subject may choose to end the relationship expressed in the certificate, thus creating cause to revoke the certificate. If one or more of the INRs bound to the public key in the certificate are no longer associated with the subject, that too constitutes a basis for revocation. A certificate also may be revoked due to loss or compromise of the private key corresponding to the public key in the certificate. Finally, a certificate may be revoked in order to invalidate data signed by the private key associated with that certificate. 4.9.2. Who Can Request Revocation The subscriber or may request a revocation. 4.9.3. Procedure for Revocation Request .> 4.9.4. Revocation Request Grace Period A subscriber is required to request revocation as soon as possible after the need for revocation has been identified. 4.9.5. Time within Which CA Must Process the Revocation Request 4.9.6. Revocation Checking Requirement for Relying Parties As per RFC 6484, a relying party is responsible for acquiring and checking the most recent, scheduled CRL from the issuer of the certificate, whenever the relying party validates a certificate. Kent, et al. Best Current Practice [Page 25] RFC 7382 Template CPS for the RPKI April 2015 4.9.7.

Security Considerations The degree to which a relying party can trust the binding embodied in a certificate depends on several factors. These factors can include o the practices followed by the Certification Authority (CA) in authenticating the subject o the CA's operating policy, procedures, and technical security controls, including the scope of the subscriber's responsibilities (for example, in protecting the private key) o the stated responsibilities and liability terms and conditions of the CA (for example, warranties, disclaimers of warranties, and limitations of liability) This document provides a framework to address the technical, procedural, personnel, and physical security aspects of Certification Authorities, Registration Authorities, repositories, subscribers, and relying party cryptographic modules, in order to ensure that the certificate generation, publication, renewal, re-key, usage, and revocation are done in a secure manner. Specifically, the following sections are oriented towards ensuring the secure operation of the PKI entities such as CA, RA, repository, subscriber systems, and relying party systems: Section 3 ("Identification and Authentication" (I&A)) Section 4 ("Certificate Life Cycle Operational Requirements") Section 5 ("Facility, Management, and Operational Controls") Section 6 ("Technical Security Controls") Section 7 ("Certificate and CRL Profiles") Section 8 ("Compliance Audit and Other Assessments") Kent, et al.
