Abstract

   This document describes the certificate policy for a PKI used to
   support applications that make use of attestations about Internet
   resource holdings. The principle application that motivated creation
   of this PKI is routing security, but other applications that rely on
   such attestations also may make use of this PKI, e.g., resource
   transfer. Each organization that allocates IP addresses or
   Autonomous System (AS) numbers to an organization will, in parallel,
   issue a certificate reflecting this allocation. These certificates

   will enable verification that the holder of the associated private
   key has been allocated the resources indicated in the certificate,
   and is the current, unique holder of these resources. The PKI in
   which the certificates issued under this policy are employed, in
   conjunction with ancillary digitally signed data structures, will
   provide critical inputs for routing security mechanisms.

Internet-Draft     Certificate Policy for the RPKI          March 2009




1. Introduction

   This document describes the certificate policy for a PKI used to
   attest to Internet resource holdings. An organization that allocates
   IP addresses or Autonomous System (AS) numbers to an organization
   will, in parallel, issue a certificate reflecting this allocation.
   These certificates will enable verification that the holder of the
   associated private key has been allocated the resources indicated in
   the certificate, and is the current, unique holder of these
   resources. The PKI in which the certificates issued under this
   policy are employed can be used in a number of ways, for example, in
   conjunction with ancillary digitally signed data structures, it can
   be used to provide critical inputs for routing security mechanisms,
   e.g., generation of route filters by ISPs. This security
   infrastructure is described in more detail in [ARCH].

   The most important and distinguishing aspect of the PKI for which
   this policy was created is that it does not purport to identify an
   address space holder or AS number holder via the subject name
   contained in the certificate issued to that entity. Rather, each
   certificate issued under this policy is intended to enable an entity
   to assert, in a verifiable fashion, that it is the current holder of
   an address block or an AS number, based on the current records of
   the entity responsible for the resources in question. Verification
   of the assertion is based on two criteria: the ability of the entity
   to digitally sign data that is verifiable using the public key
   contained in the corresponding certificate, and validation of that
   certificate in the context of this PKI. This PKI is designed
   exclusively for use in support of validation of claims related to
   address space and AS number holdings, with initial emphasis on
   support of routing security mechanisms. Use of the certificates and
   CRLs managed under this PKI for any other purpose is a violation of
   this CP, and relying parties should reject certificates presented
   for such uses.

   Note that while the initial focus of the RPKI is routing security
   applications, other applications that make use of attestations of IP
   address or AS number resource holdings are within the scope of the
   RPKI, e.g., resource transfer applications.

   Note: This document is based on the template specified in the
   Internet Engineering Task Force (IETF) standards document RFC 3647.
   A number of sections contained in the template were omitted from
   this policy because they did not apply to this PKI. However, we have
   retained the section numbering scheme employed in the RFC to
   facilitate comparison with the RFC. The first digit from the RFC



Seo,Watro,Kong&Kent     Expires September 2009                  [Page 7 






Internet-Draft     Certificate Policy for the RPKI          March 2009


   ("4") has been omitted and in cases where the RFC had bulleted
   items, we added a third level of numbering.  So for example, RFC
   3647's item 4.4.8 ("Certificate Modification") is listed here as
   just 4.8.  The first bullet under this item ("Circumstances under
   which certificate modification can take place...") is listed here as
   4.8.1.

1.1. 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 RFC-2119 [RFC2119].

1.2. Overview

   This PKI is designed to support validation of claims by current
   holders of IP (v4 and v6) address space, and AS numbers, in
   accordance with the (current) records of the organizations that act
   as CAs in this PKI. The ability to verify such claims is essential
   to ensuring the unique, unambiguous allocation of these resources,
   and this, in turn, is an essential underpinning of routing in the
   public Internet.

   The proposed security infrastructure consists of three components: a
   PKI, repositories, and related, digitally signed objects (e.g.,
   route origination authorizations (ROAs)). The PKI authoritatively
   documents the current allocation of address blocks and AS numbers to
   organizations, as recorded by the organizations that manage such
   allocations. (For brevity, this document uses the term
   "organization" to refer to every resource holder, even if the holder
   is an individual.) Repositories provide the means of publishing the
   PKI data (certificates and CRLs) and signed object data in a manner
   that makes it available to relying parties. The intent is for each
   network operator to upload its new or updated PKI and signed object
   data periodically to its publication repository, e.g., daily. On a
   similar schedule, each network operator also is expected to download
   new or updated data that has been published by others.

   This PKI parallels the existing IP address and AS number allocation
   hierarchy. These resources are allocated by the Internet Assigned
   Numbers Authority (IANA) to the Regional Internet Registries (RIRs -
   AFRINIC (Africa), APNIC (Asia-Pacific), ARIN (North America), LACNIC
   (Latin America and Caribbean), and RIPE NCC (Europe) and by the RIRs
   to other organizations. Together IANA and the RIRs act as default
   trust anchors for the PKI.  In some regions, National Internet
   Registries (NIRs) form a tier of the hierarchy below the RIRs for
   address allocation. ISPs and network subscribers form additional
   tiers below registries. (ISPs who acquire allocations from RIRs or



Seo,Watro,Kong&Kent     Expires September 2009                  [Page 8 






Internet-Draft     Certificate Policy for the RPKI          March 2009


   NIRs, and who sub-allocate address space are referred to as Local
   Internet Registries (LIRs)).

   This PKI encompasses several types of certificates (see IETF
   document draft-ietf-sidr-arch-xx [ARCH] for more details):

  . CA certificates for each organization allocating address blocks
     and/or AS numbers, and for each address space (AS number) holder

  . End entity (EE) certificates for organizations to use in verifying
     ROAs and other (non-certificate/CRL) signed objects

  . In the future, the PKI also may include end entity certificates in
     support of access control for the repository system

1.3. Document name and identification

   The name of this document is "Certificate Policy (CP) for the
   Resource PKI (RPKI)".

   This policy has been assigned the following OID:

   id-cp-ipAddr-asNumber

       OBJECT IDENTIFIER ::= { iso(1) identified-organization(3)

                dod(6) internet(1) security(5) mechanisms(5) pkix(7)
   cp(14) 2 }

1.4. PKI participants

   Note: 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.  Thus, in this PKI, the term "subscriber" can
   refer both to ISPs, which can be subscribers of RIRs, NIRs, and
   LIRs, and also to organizations that are not ISPs, but which are
   subscribers of ISPs in the networking sense of the term. Also note
   that, for brevity, this document always refers to subscribers as
   organizations, even though some subscribers are individuals. When
   necessary, the phrase "network subscriber" is used to refer to an
   organization that receives network services from an ISP.

Internet-Draft     Certificate Policy for the RPKI          March 2009


1.4.1. Certification authorities

   The organizations that allocate IP addresses (IANA, RIRs, NIRs,
   LIRs/ISPs) and AS numbers (IANA, RIRs and NIRs) act as CAs in this
   PKI.

   Organizations that hold address space and create and sign objects
   such as ROAs and manifests also act as CAs in this PKI. Such
   organizations will include internet number registries, LIRs/ISPs,
   provider-independent subscribers and some dual-homed subscribers.
   For each signed object an organization creates, it will issue a
   corresponding EE certificate that will be used to validate the
   digital signature on the signed object. (Organizations may issue
   other types of EE certificates in the future). See [ARCH] for more
   details.

1.4.2. Registration authorities

   This PKI does not require establishment or use of a separate
   registration authority (RA) in conjunction with the CA function. The
   RA function will be provided by the same entity operating as a CA,
   e.g., entities listed in Section 1.3.1. An entity acting as a CA in
   this PKI already has a formal relationship with each organization to
   which it allocates IP address space and/or AS number resources.
   These organizations already perform the RA function implicitly since
   they already assume responsibility for allocating and tracking the
   current allocation of address space and AS numbers.

1.4.3. Subscribers

   These are the organizations receiving allocations of IP addresses
   and AS numbers - RIRs, NIRs, LIRs, ISPs, and other organizations.
   See [ARCH] for more details.

   Note that any of these organizations may have received allocations
   from more than one source, over time. This is true even for RIRs,
   which participate in inter-registry exchanges of address space. This
   PKI accommodates such relationships.

1.4.4. Relying parties

   Entities that need to validate claims of address space and/or AS
   number current holdings are relying parties.  Thus, for example,
   entities that make use of address and AS number allocation
   certificates in support of improved routing security are relying

   BGP traffic with ISPs, and subscribers who have received an

   allocation of address space from ISP A but want to authorize ISP B
   to originate routes to this space.

   To the extent that repositories make use of certificates issued
   under this PKI for access control -- checking for authorization to
   upload certificate, CRL, and ROA update packages -- they too act as
   relying parties.

1.4.5. Other participants

   Every organization that undertakes a role as a CA in this PKI is
   responsible for populating the RPKI distributed repository system
   with the certificates, CRLs, and other signed objects that it
   issues. The organization can operate its own publication point or
   outsource this function (See sections 2.1 and 2.2.)

1.5. Certificate usage

1.5.1. Appropriate certificate uses

   The certificates issued under this hierarchy are for authorization
   in support of validation of claims of current holdings of address
   space and/or AS numbers, e.g., for routing security. Additional uses
   of the PKI, consistent with the basic goal cited above, are also
   permitted under this policy.

   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. Such uses also are permitted
   under this policy.

1.5.2. Prohibited certificate uses

   Any uses other than those described in Section 1.4.1 are prohibited
   under this policy.

1.6. Policy administration

1.6.1. Organization administering the document

   This CP is co-administered by IANA and the five Regional Internet
   Registries (RIRs), which act as default trust anchors for the PKI:

1.6.3. Person determining CP suitability for the policy

   Not applicable. Each organization issuing a certificate in this PKI
   is attesting to the allocation of resources (IP addresses, AS
   numbers) to the holder of the private key corresponding to the
   public key in the certificate. These are the same organizations that
   perform the allocation hence they are authoritative with respect to
   the accuracy of this binding.

1.6.4. CP approval procedures

   Not applicable. Each organization issuing a certificate in this PKI
   is attesting to the allocation of resources (IP addresses, AS
   numbers) to the holder of the private key corresponding to the
   public key in the certificate. The issuing organization is the same
   organization as the one that performs the allocation.

1.7. Definitions and acronyms

BGP -  Border Gateway Protocol.  This is the protocol used in the
       Internet for propagating the connectivity information used as a
       basis for inter-domain routing. [BGP4]

CPS -  Certification Practice Statement. A CPS is a document that
       specifies the practices that a Certification Authority employs
       in issuing certificates. [e.g., CPS-1, CPS-2]

IANA - Internet Assigned Numbers Authority. IANA is responsible for
       global coordination of the Internet Protocol addressing systems
       and Autonomous System (AS) numbers used for routing internet
       traffic. IANA allocates IP addresses and AS numbers to Regional
       Internet Registries (RIRs).

ISP -  Internet Service Provider. This is an organization managing and
       selling Internet services to other organizations.

LIR -  Local Internet Registry. This is an organization, typically a
       network service provider, that sub-allocates the assignment of
       IP addresses for a portion of the area covered by a Regional (or
       National) Registry.

NIR -  National Internet Registry. This is an organization that manages
       the assignment of IP address and AS numbers for a portion of the
       geopolitical area covered by a Regional Registry.  NIRs form an
       optional second tier in the tree scheme used to manage IP
       address and AS number allocation.

NRO -  Number Resource Organization. This organization was formed by
       the Regional Internet Registries (RIRs) for the purpose of
       undertaking joint activities of the five RIRs, including joint
       technical projects, liaison activities, and policy coordination.

RIR -  Regional Internet Registry.  This is an organization that
       manages the assignment of IP address and AS numbers for a
       geopolitical area.  At present, there are five RIRs: AFRINIC
       (Africa), APNIC (Asia-Pacific), ARIN (North America), LACNIC
       (Latin America and Caribbean), and RIPE NCC (Europe).

2. Publication And Repository Responsibilities

2.1. Repositories

   Certificates, CRLs, and related signed objects must be made
   available for downloading by all relying parties, to enable them to
   validate this data. This motivates use of a robust, distributed
   repository system. Each CA is responsible for publishing its signed
   products (certificates, CRLs, manifests, ROAs, etc.) at a dedicated
   publication point. The RPKI distributed repository system is the
   collection of these dedicated publication points. An organization
   may choose to outsource the publication of PKI data. (See [REPOS]
   for further details.)

2.2. Publication of certification information

   All CAs will publish certificates via the repository system.

   Each CA will publish the CRL(s) that it issues by uploading to the
   repository system.

   ROAs and other signed objects will be uploaded to the repository
   system by address space holders, e.g., network subscribers and
   ISPs/LIRs.

   An organization may choose to outsource publication of RPKI data -
   certificates, CRLs, and other signed objects. (See [REPOS] for
   further details.).

2.3. Time or frequency of publication

   The CPS for each CA will specify the following information:

   The period of time within which a certificate will be published
   after the CA issues the certificate.

   The period of time within which a CA will publish a CRL with an
   entry for a revoked certificate after it revokes that certificate.
   Note that each CA MUST publish its CRL prior to the
   nextScheduledUpdate value in the scheduled CRL previously issued by
   the CA.

2.4. Access controls on repositories

   Access to the repository system, for modification of entries, must
   be controlled to prevent denial of service attacks. All data
   (certificates, CRLs, etc.) uploaded to a repository are digitally
   signed. Updates to the repository system must be validated to ensure

   that the data being added or replaced is authorized. This document
   does not define the means by which updates are verified, but use of
   the PKI itself to validate updates is anticipated.

3. Identification and Authentication

3.1. Naming

3.1.1. Types of names

   Names for IANA and RIRs will be directory distinguished names, using
   a subset of the following attributes: C, O, OU, and CN. Names for
   all other CAs and all end entities will consist of a single CN
   attribute with a value generated by the issuer.

3.1.2. Need for names to be meaningful

   The Subject name in each certificate must be unique relative to all
   Subject names certified by an Issuer, but the name does not need to
   be meaningful. There is no requirement, and no guarantee, that
   subject names are globally unique in this PKI. The certificates
   issued under this PKI are used for authorization in support of
   applications that make use of attestations of Internet resource
   holding, not for identification. The PKI binds a public key to sets
   of address blocks, and/or sets of AS numbers. The name of the holder
   of the address block or AS number is not intended to be
   "meaningful". For purposes of routing security, the issuer and
   subject name in each certificate are not relevant, other than their
   needing to meet the usual PKI requirements for contextual uniqueness
   in support of unambiguous certificate path chaining.

3.1.3. Anonymity or pseudonymity of subscribers

   Although Subject (and Issuer) names need not be meaningful, and may
   appear "random," anonymity is not a function of this PKI, and thus
   no explicit support for this feature is provided.

3.1.4. Rules for interpreting various name forms

   None

3.1.5. Uniqueness of names

   Each CA certifies Subject names that must be 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 neither mandated nor
   enforced through technical means.

Internet-Draft     Certificate Policy for the RPKI          March 2009


3.1.6. Recognition, authentication, and role of trademarks

   Because the Subject names are not intended to be meaningful, there
   is no provision to recognize or authenticate trademarks, service
   marks, etc.

3.2. Initial identity validation

3.2.1. Method to prove possession of private key

   Each CA operating within the context of this PKI will require each
   Subject to demonstrate proof-of-possession (PoP) of the private key
   corresponding to the public key in the certificate, prior to issuing
   the certificate. The means by which PoP is achieved is determined by
   each CA and will be declared in the CPS of that CA.

3.2.2. Authentication of organization identity

   Each CA operating within the context of this PKI will employ
   procedures to ensure that each certificate it issues accurately
   reflects its records with regard to the organization to which the CA
   has allocated (or sub-allocated) the address space identified in the
   certificate. The same requirement is imposed on the binding of one
   or more AS numbers in a certificate to the organization represented
   by the Subject. The specific procedures employed for this purpose
   are described by the CPS for each CA. Relying parties can expect
   each CA to employ procedures commensurate with those it already
   employs as a registry or ISP, in the maintenance of address (and AS
   number) allocation.

3.2.3. Authentication of individual identity

   Each CA operating within the context of this PKI will employ
   procedures to identify at least one individual as a representative
   of each organization that is an address space (AS number) holder.
   This is done in support of issuance, renewal, and revocation of the
   certificate issued to the organization. The specific means by which
   each CA authenticates individuals as representatives for an
   organization are described by the CPS for each CA. Relying parties
   can expect each CA to employ procedures commensurate with those it
   already employs as a registry or ISP, in authenticating individuals
   as representatives for address space (AS number) holders. Moreover,
   this authentication is solely for use by each CA in dealing with the
   organizations to which it allocates (or sub-allocates) address space
   (or AS numbers), and thus must not be relied upon outside of this
   CA-subscriber relationship.

Internet-Draft     Certificate Policy for the RPKI          March 2009


3.2.4. Non-verified subscriber information

   No non-verified subscriber data is included in certificates issued
   under this certificate policy.

3.2.5. Validation of authority

   Each CA operating within the context of this PKI will employ
   procedures to verify that an individual claiming to represent an
   organization to which a certificate is issued, is authorized to
   represent that organization in this context. The procedures are
   described by the CPS for the CA Relying parties can expect each CA
   to employ procedures commensurate with those it already employs as a
   registry or ISP, in authenticating individuals as representatives
   for address space (AS number) holders.

3.2.6. Criteria for interoperation

   This PKI is neither intended nor designed to interoperate with any
   other PKI.

3.3. Identification and authentication for re-key requests

3.3.1. Identification and authentication for routine re-key

   Each CA operating within the context of this PKI will employ
   procedures to ensure that an organization requesting a re-key is the
   legitimate holder of the certificate (and associated address space
   and AS numbers) to be re-keyed and will require PoP of the private
   key corresponding to the new public key. The procedures employed for
   these purposes are described in the CPS for the CA. With respect to
   authentication of the holder of the address space and AS numbers,
   relying parties can expect each CA to employ procedures commensurate
   with those it already employs as a registry or ISP, in the
   maintenance of address (and AS number) allocation.

   Note: An issuer may choose to require periodic re-keying consistent
   with contractual agreements with the recipient. If so, this will be
   described by the CPS for the CA.

3.3.2. Identification and authentication for re-key after revocation

   Each CA operating within the context of this PKI will employ
   procedures to ensure that an organization requesting a re-key after
   revocation is the legitimate holder of the certificate (and
   associated address space and AS numbers) to be re-keyed and will
   require PoP of the private key corresponding to the new public key.
   The specific procedures employed for these purposes will be

   described by the CPS for the CA.  With respect to authentication of
   the holder of the address space and AS numbers, relying parties can
   expect each CA to employ procedures commensurate with those it
   already employs as a registry or ISP, in the maintenance of address
   (and AS number) allocation. Note that there may be different
   procedures for the case where the legitimate subject still possesses
   the original private key as opposed to the case when it no longer
   has access to that key.

3.4. Identification and authentication for revocation request

   Each CA operating within the context of this PKI will employ
   procedures to ensure that an organization requesting revocation is
   the legitimate holder of the certificate (and associated address
   space and AS numbers) to be revoked. The specific procedures
   employed for these purposes will be described by the CPS for the CA.
   Relying parties can expect each CA to employ procedures commensurate
   with those it already employs as a registry or ISP, in the
   maintenance of address (and AS number) allocation.

   Note:  If new IP addresses or AS numbers are being added to an
   organization's existing allocation, the old certificate need not be
   revoked. Instead, a new certificate may issued with both the old and
   the new resources and the old key. If IP addresses or AS numbers are
   being removed or if there has been a key compromise, then the old
   certificate must be revoked (and a re-key must be performed in the
   event of key compromise).

4. Certificate Life-Cycle Operational Requirements

4.1. Certificate Application

4.1.1. Who can submit a certificate application

   The Resource PKI issues several types of certificates. Any entity
   that assigns Internet IP address space or AS numbers should acquire
   a certificate. This includes registries and ISPs. Additionally,
   entities that hold AS numbers or that have address space assignments
   from a registry, or that are multi-homed, should acquire a
   certificate under this PKI, even if they do not exchange BGP UPDATEs
   with ISPs. The (CA) certificates issued to these entities will
   include one or both of the extensions defined by RFC 3779, X.509
   Extensions for IP Addresses and AS Identifiers, as appropriate.

   Most of the certificates in this PKI are issued as part of registry
   and ISP normal business practices, as an adjunct to address space
   and AS number allocation, and thus a separate specific application
   to request a certificate usually will not be necessary.

4.1.2. Enrollment process and responsibilities

   The enrollment process and procedures will be described by the CPS
   for each CA.  An entity that desires one or more certificates should
   contact the organization from which it receives IP address space or
   AS number allocations. During the initial deployment of this PKI, an
   organization that already has resource allocations should contact
   the organization from which the resources were acquired to obtain
   appropriate credentials.

4.2. Certificate application processing

   CAs should make use of existing standards for certificate
   application processing.  Relevant standards include RFC 4210,
   Internet X.509 Public Key Infrastructure Certificate Management
   Protocol (CMP), RFC 2797, Certificate Management Messages over CMS,
   and RSA Labs standards PKCS #7 and PKCS #10. Each CA will define the
   certificate request/response standards that it employs, via its CPS.

4.2.1. Performing identification and authentication functions

   Existing practices employed by registries and ISPs to identify and
   authenticate organizations form the basis for issuance of
   certificates to these subscribers. It is important to note that the
   Resource PKI is never used to authenticate the identity of an
   organization, but rather to bind subscribers to the address blocks
   and AS numbers they hold.  Because identity is not being vouched for



Seo,Watro,Kong&Kent     Expires September 2009                 [Page 21 






Internet-Draft     Certificate Policy for the RPKI          March 2009


   by this PKI, certificate application procedures need not verify
   legal organization names, etc.

4.2.2. Approval or rejection of certificate applications

   Certificate applications will be approved based on the normal
   business practices of the entity operating the CA, based on the CA's
   records of address space and AS number holders. Each CA will verify
   that the requester holds the corresponding private key for the
   public key that will be bound to the certificate the CA issues to
   the requestor. The details of how certificate applications are
   approved are described in the CPS for the CA in question.

4.2.3. Time to process certificate applications

   No stipulation. Each CA may declare its expected time frame for
   processing certificate applications as part of its CPS.

4.3. Certificate issuance

4.3.1. CA actions during certificate issuance

   If a CA determines that the request is acceptable, it will issue the
   corresponding certificate and publish it in the RPKI distributed
   repository system via publication of the certificate at the CA's
   repository publication point.

4.3.2. Notification to subscriber by the CA of issuance of certificate

   The CA will notify the subscriber when the certificate is published.
   The means by which a subscriber is notified is defined by each CA in
   its CPS.

4.3.3. Notification of certificate issuance by the CA to other entities

   The CPS of each CA will indicate whether any other entities will be
   notified when a certificate is issued.

4.4. Certificate acceptance

4.4.1. Conduct constituting certificate acceptance

   Within the timeframe specified in its CPS, the CA will place the
   certificate in the repository and notify the subscriber.  This will
   be done without subscriber review and acceptance. Each CA shall
   state in its CPS the procedures it follows for publishing of the
   certificate and notification to the subscriber.




Seo,Watro,Kong&Kent     Expires September 2009                 [Page 22 






Internet-Draft     Certificate Policy for the RPKI          March 2009


4.4.2. Publication of the certificate by the CA

   Certificates will be published in the RPKI distributed repository
   system via publication of the certificate at the CA's repository
   publication point as per the conduct described in 4.4.1. The
   procedures for publication are defined by each CA in its CPS.

4.5. Key pair and certificate usage

   A summary of the use model for the Resource PKI is provided below.

4.5.1. Subscriber private key and certificate usage

   Each holder of an address space or AS number allocation will be
   issued an X.509 CA certificate containing appropriate RFC 3779
   extensions. When the subjects of these certificates are LIRs/ISPs or
   network subscribers, they also shall issue EE certificates to
   themselves to enable verification of signed objects that they
   generate.

4.5.2. Relying party public key and certificate usage

   The relying parties in this PKI are entities who need to verify
   signed assertions about Internet resource holdings.

4.6. Certificate renewal

4.6.1. Circumstance for certificate renewal

   A certificate should be processed for renewal based on its
   expiration date or a renewal request from the certificate Subject.
   If the issuing CA initiates the renewal process based on the
   certificate expiration date, then that CA shall notify the holder in
   advance of the renewal process. The validity interval of the new
   (renewed) certificate should overlap that of the previous
   certificate, to ensure uninterrupted coverage.

   Certificate renewal should incorporate the same public key as the
   previous certificate, unless the private key has been reported as
   compromised. If a new key pair is being used, the stipulations of
   Section 4.7 will apply.

4.6.2. Who may request renewal

   The certificate holder or the issuing CA may initiate the renewal
   process. For example, a certificate holder may request an early
   renewal if it wishes to change the public key, or if it expects to




Seo,Watro,Kong&Kent     Expires September 2009                 [Page 23 






Internet-Draft     Certificate Policy for the RPKI          March 2009


   be unavailable to support the renewal process at the normal
   expiration cycle.

4.6.3. Processing certificate renewal requests

   Renewal processing must verify that the certificate in question has
   not been revoked.

4.6.4. Notification of new certificate issuance to subscriber

   No additional stipulations beyond those of section 4.3.2.

4.6.5. Conduct constituting acceptance of a renewal certificate

   No additional stipulations beyond those of section 4.4.1.

4.6.6. Publication of the renewal certificate by the CA

   No additional stipulations beyond those of section 4.4.2.

4.6.7. Notification of certificate issuance by the CA to other entities

   The CPS of each CA will indicate whether any other entities will be
   notified when a certificate is issued.

4.7. Certificate re-key

4.7.1. Circumstance for certificate re-key

   Re-key of a certificate should 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

   The re-key operation can have dramatic consequences, requiring the
   re-issuance of all certificates issued by a re-keyed entity, so it
   should be performed only when necessary.  In particular, if a
   certificate is revoked to replace the RFC 3779 extensions, the
   replacement certificate should incorporate the same public key
   rather than a new key.

   If the re-key is based on a suspected compromise, then the previous
   certificate must be revoked.




Seo,Watro,Kong&Kent     Expires September 2009                 [Page 24 






Internet-Draft     Certificate Policy for the RPKI          March 2009


   Section 5.6 below notes that when a CA signs a certificate, the
   signing key should have a validity period that exceeds the validity
   period of the certificate. This places additional constraints on
   when a CA should request a re-key.

4.7.2. Who may request certification of a new public key

   The holder of the certificate may request a re-key.  In addition,
   the CA that issued the certificate may initiate a rekey based on a
   verified compromise report. Note that care must be taken to verify
   the authorization of a subscriber to request a re-key when the
   private key has been reported as compromised.

4.7.3. Processing certificate re-keying requests

   The re-key process follows the general procedures of certificate
   generation as defined in section 4.3.

4.7.4. Notification of new certificate issuance to subscriber

   No stipulation beyond the notification process for any new
   certificate (see section 4.3.2)

4.7.5. Conduct constituting acceptance of a re-keyed certificate

   No stipulation beyond the acceptance process for any new certificate
   (see section 4.4.1)

4.7.6. Publication of the re-keyed certificate by the CA

   No stipulation beyond the publication process for any new
   certificate (see section 4.4.2)

4.7.7. Notification of certificate issuance by the CA to other entities

   The CPS of each CA will indicate whether any other entities will be
   notified when a certificate is issued.

4.8. Certificate modification

4.8.1. Circumstance for certificate modification

   Modification of a certificate occurs to implement changes to
   selected attribute values in a certificate. In the context of this
   PKI, the only changes that are accommodated by certificate
   modification are additions to the address space and/or AS number
   holdings described by the RFC 3779 extension.

Internet-Draft     Certificate Policy for the RPKI          March 2009


   When previously allocated address space or AS numbers are removed
   from a certificate, then the old certificate is revoked and a new
   certificate is issued.

   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 address space and AS
   allocations expanded.  Revocation of the previous certificate is not
   required.

4.8.2. Who may request certificate modification

   The certificate holder or issuer may initiate the certificate
   modification process.

4.8.3. Processing certificate modification requests

   The CA must determine that the requested modification is appropriate
   and that the procedures for the issuance of a new certificate are
   followed.

4.8.4. Notification of new certificate issuance to subscriber

   No stipulation beyond the notification process for any new
   certificate (see section 4.3.2)

4.8.5. Conduct constituting acceptance of modified certificate

   No stipulation beyond the acceptance process for any new certificate
   (see section 4.4.1).

4.8.6. Publication of the modified certificate by the CA

   No stipulation beyond the publication process for any new
   certificate (see section 4.4.2).

4.8.7. Notification of certificate issuance by the CA to other entities

   The CPS of each CA will indicate whether any other entities will be
   notified when a certificate is issued.

4.9. Certificate revocation and suspension

4.9.1. Circumstances for revocation

   Certificates can be revoked for several reasons. Either the issuer
   or subject may choose to end the relationship expressed in the
   certificate, thus creating cause to revoke the certificate  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, e.g., a
   manifest or ROA.

4.9.2. Who can request revocation

   The certificate holder or issuer may request a revocation.

4.9.3. Procedure for revocation request

   A certificate holder must submit a request to the certificate issuer
   for a revocation. A certificate issuer must notify the certificate
   holder when revoking a certificate, however this notification
   requirement is satisfied by publication of a CRL by the issuer.

4.9.4. Revocation request grace period

   A subscriber should request revocation as soon as possible after the
   need for revocation has been identified. There is no specified grace
   period for the subscriber in this process.

4.9.5. Time within which CA must process the revocation request

   No stipulation. Each CA is free to specify its expected revocation
   processing time in its CPS.

4.9.6. Revocation checking requirement for relying parties

   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.

4.9.7. CRL issuance frequency

   The CRL issuance frequency is determine by each CA and stated in its
   CPS. Each CRL carries a nextScheduledUpdate value and a new CRL must
   be published at or before that time. A CA must set the
   nextScheduledUpdate value when it issues a CRL, to signal when the
   next scheduled CRL will be issued.

Internet-Draft     Certificate Policy for the RPKI          March 2009


4.9.8. Maximum latency for CRLs

   The CPS for each CA will specify the maximum latency associated with
   posting its CRL to the repository system.

4.10. Certificate status services

   This PKI does not make use of OCSP or SCVP, because it is
   anticipated that the primary relying parties (ISPs) will acquire and
   validate certificates for all participating resource holders on a
   daily basis. These protocols are not designed for such large-scale,
   bulk certificate status checking. Instead, retrieval of all changed
   or new certificates and CRLs on a daily basis is the anticipated
   mode of certificate status verification.

5. Facility, Management, And Operational Controls

5.1. Physical controls

   Each CA will maintain physical security controls for its operation
   that are commensurate with those employed by the organization in the
   management of address space and AS number allocation. The details
   for each CA will be specified in its CPS.

5.2. Procedural controls

   Each CA is expected to maintain procedural security controls that
   are commensurate with those employed by the organization in the
   management of address space and AS number allocation. The details
   for each CA will be specified in its CPS.

5.3. Personnel controls

   Each CA will maintain personnel security controls that are
   commensurate with those employed by the organization in the
   management of address space and AS number allocation. The details
   for each CA will be specified in its CPS.

5.4. Audit logging procedures

   Details of how a CA implements the audit logging described in this
   section (5.4.1 to 5.4.8) will be addressed in its CPS.

5.4.1. Types of events recorded

   Audit records should be generated for the basic operations of the
   certification authority computing equipment.  Audit records should
   include the date, time, responsible user or process, and summary
   content data relating to the event.  Auditable events include

  . Access to CA computing equipment (e.g., logon, logout)

  . Messages received requesting CA actions  (e.g., certificate
     requests, certificate revocation requests, compromise
     notifications)

  . Certificate creation, modification, revocation, or renewal actions

  . Posting of any material to a repository

  . Any attempts to change or delete audit data

Internet-Draft     Certificate Policy for the RPKI          March 2009


5.4.2. Frequency of processing log

   Each CA will establish its own procedures for review of audit logs.

5.4.3. Retention period for audit log

   Each CA will establish its own polices for retention of audit logs.

5.4.4. Protection of audit log

   The audit log should be protected based on current industry
   standards.

5.4.5. Audit log backup procedures

   The audit log should be backed up based on current industry
   standards.

5.4.8. Vulnerability assessments

   The PKI subsystems of a registry or ISP should participate in any
   vulnerability assessments that these organizations run as part of
   their normal business practice.

5.6. Key changeover

   When a CA wishes to change keys, it must acquire a new certificate
   containing the public key of the pair, well in advance of the
   scheduled change of the current signature key pair.

   Ideally, the private key that a CA uses to sign a certificate or CRL
   should have a validity period that is at least as long as that of
   any certificate being signed. However, since a certificate issued
   under this PKI may have a validity period that reflects the
   contractual relationship between the issuer and subject, this may
   lead to situations where an issued certificate has a validity period
   longer than that of the key used to sign the certificate.

5.8. CA or RA termination

   In this PKI, each CA is authoritative for a specified range of IP
   addresses and a specified set of AS numbers. If an organization
   acting as a CA in this PKI terminates operation without identifying
   a replacement, then the effective control of the IP addresses and AS
   numbers revert back to the issuing organization, and address space
   and AS number allocations that have been previously validated via
   that CA are invalidated as of revocation of the CA's certificate.

Internet-Draft     Certificate Policy for the RPKI          March 2009


6. Technical Security Controls

   The organizations that allocate IP addresses and AS numbers to
   subscribers are authoritative for these allocations. This PKI is
   designed to enable LIRs/ISPs and network subscribers to demonstrate
   that they are the holders of the resources that have been allocated
   to them. Accordingly, the security controls used by CAs and
   subscribers for this PKI need only to be as secure as those that
   apply to the procedures for administering the allocation of IP
   address space and AS number data by the extant organizations.
   Details of each CA's security controls are described in the CPS
   issued by the CA.

6.1. Key pair generation and installation

6.1.1. Key pair generation

   In most instances, public-key pairs will be generated by the
   subject, i.e., the organization receiving the allocation of address
   space or AS numbers.  However, some CAs may offer to generate key
   pairs on behalf of their subjects at the request of the subjects,
   e.g., to accommodate subscribers who do not have the ability to
   perform key generation in a secure fashion. Since the keys used in
   this PKI are not for non-repudiation purposes, generation of key
   pairs by CAs does not inherently undermine the security of the PKI.
   Each CA will describe its key pair generation procedures in its CPS.

6.1.2. Private key delivery to subscriber

   If a CA provides key pair generation services for subscribers, its
   CPS will describe the means by which private keys are delivered to
   subscribers in a secure fashion.

6.1.3. Public key delivery to certificate issuer

   Each CA operating within the context of this PKI defines procedures
   whereby a subscriber requests IP address space (and/or AS numbers),
   authenticates itself, pays for the resources, etc. The CPS of each
   CA will describe how these procedures are extended to support
   certificate issuance. The security of the procedures used by a
   subject to deliver its public key to a CA need only be commensurate
   with the security of the procedures already employed for management
   of the IP address space and AS numbers.

6.1.4. CA public key delivery to relying parties

   CA public keys for all entities other than default trust anchors are
   contained in certificates issued by other CAs. These certificates



Seo,Watro,Kong&Kent     Expires September 2009                 [Page 31 






Internet-Draft     Certificate Policy for the RPKI          March 2009


   will be published in the RPKI distributed repository system. Relying
   parties will download these certificates from the repositories.
   Public key values and associated data for the default trust anchors
   will be distributed out of band, e.g., embedded in path validation
   software that will be made available to the Internet community.

6.1.5. Key sizes

   For RIR and IANA certificates, the RSA key size will be 2048 bits.
   For all other certificates, the RSA keys will be either 2048 or 1024
   bits.

6.1.6. Public key parameters generation and quality checking

   The RSA algorithm [RSA] is used in this PKI with the public exponent
   (e) F4 (65,537). Each subscriber is responsible for performing
   checks on the quality of its key pair. CAs are not responsible for
   performing such checks for subscribers.

6.1.7. Key usage purposes (as per X.509 v3 key usage field)

   The Key usage extension bit values shall be consistent with RFC
   3280. For CA certificates, the keyCertSign and cRLSign bits shall be
   set TRUE. All other bits (including digitalSignature) shall be set
   FALSE, and the extension shall be marked critical. End entity
   certificates in this PKI may include this extension, with
   appropriate bit values, as per RFC 3280, but such inclusion is not
   required.

6.2. Private Key Protection and Cryptographic Module Engineering
   Controls

6.2.1. Cryptographic module standards and controls

   The cryptographic module standards and controls employed by each CA
   will be described in the CPS issued by that CA.

6.2.2. Private key (n out of m) multi-person control

   CAs may employ multi-person controls to constrain access to their
   private keys, but this is not a requirement for all CAs in the PKI.
   The CPS for each CA will describe which, if any, multi-person
   controls it employs.

6.2.3. Private key escrow

   No private key escrow procedures are required for this PKI.

Internet-Draft     Certificate Policy for the RPKI          March 2009


6.2.4. Private key backup

   Because of the adverse operational implications associated with the
   loss of use of a CA private key in the PKI, each CA should employ a
   secure means to backup its private keys. The details of the
   procedures for backing up a CA's private key will be described in
   the CPS issued by the CA.

6.3. Other aspects of key pair management

6.3.1. Public key archival

   Because this PKI does not support non-repudiation, there is no need
   to archive public keys.

6.3.2. Certificate operational periods and key pair usage periods

   The resource allocations held by RIRs and the NIRs periodically
   change because these registries receive new allocations. Therefore
   it is appropriate for their certificates to have lifetimes that
   match the periodicity of these changes.  However, to minimize
   disruption, the key pairs should be maintained across certificate
   changes.

   If LIR/ISP and subscriber certificates are tied to the duration of
   service agreements, these certificates should have validity periods
   commensurate with the duration of these agreements. In any case, the
   validity period for certificates will be chosen by the issuing CA
   and described in its CPS.

6.5. Computer security controls

   Each CA will document the technical security requirements it employs
   for CA computer operation in its CPS.

6.6. Life cycle technical controls

6.6.1. System development controls

   The CPS for each CA will document any system development controls
   required by that CA, if applicable.

6.6.2. Security management controls

   The CPS for each CA will document the security controls applied to
   the software and equipment used for this PKI. These controls shall
   be commensurate with those used for the systems used by the CAs for
   managing and allocating IP address and AS number resources.

Internet-Draft     Certificate Policy for the RPKI          March 2009


6.6.3. Life cycle security controls

   The CPS for each CA will document how the equipment (hardware and
   software) used for this PKI shall be procured, installed,
   maintained, and updated. This will be done in a fashion commensurate
   with the way in which equipment for the management and allocation of
   IP address space and AS numbers is handled.

6.7. Network security controls

   The CPS for each CA will document the network security controls
   employed for CA operation. These should be commensurate with the
   protection it employs for the computers used for managing allocation
   of IP addresses and AS numbers.

6.8. Time-stamping

   The PKI in question does not make use of time stamping.

8. Compliance Audit And Other Assessments

   The Certificate Policy for a typical PKI defines the criteria
   against which prospective CAs are evaluated and establishes
   requirements that they must meet. In this PKI, the CAs are already
   authoritative for the management of IP address space and AS numbers,
   and the PKI simply supports verification of the allocation if these
   resources to subscribers. Accordingly, whatever audit and other
   assessments are already used to ensure the security of the
   administration of IP addresses and AS numbers is sufficient for this
   PKI. The CPS for each CA will describe what audits and other
   assessments are used.

9. Other Business And Legal Matters

   As noted throughout this certificate policy, the organizations
   managing the allocation of IP addresses and AS numbers are
   authoritative in their roles as managers of this data. They will
   operate this PKI to allow the holders of address space and AS number
   allocations to generate digitally signed data that attest to these
   allocations. Therefore, the manner in which the organizations in
   question manage their business and legal matters for this PKI should
   be commensurate with the way in which they already manage business
   and legal matters in their existing roles. Since there is no single
   set of responses to this section that would apply to all
   organizations, the topics listed in sections 4.9.1 to 4.9.11 and
   4.9.13 to 4.9.17 of RFC 3647 should be covered in the CPS issued by
   each CA, although not every CA may choose to address all of these
   topics.

9.12. Amendments

9.12.1. Procedure for amendment

   The procedure for amendments to this CP is via written notice from
   IANA and the Regional Internet Registries (RIRs).

9.12.2. Notification mechanism and period

   The IANA and the RIRs will provide one month's notice of a change to
   this CP.

9.12.3. Circumstances under which OID must be changed

   If the IANA and the RIRs judge that the change(s) will not
   materially reduce the acceptability of certificates for RPKI
   purposes, then there will be no change to the CP OID. If they judge
   that the change(s) will materially change the acceptability of
   certificates for RPKI purposes, then there will be a new CP OID.

10. Security Considerations

   According to X.509, a certificate policy (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." A CP may be used by a relying party to help
   in deciding whether a certificate, and the binding therein, are
   sufficiently trustworthy and otherwise appropriate for a particular
   application. This document describes the CP for the Internet Address
   and AS Number PKI.  There are separate documents (Certification
   Practice Statements (CPS's) that cover the factors that determine
   the degree to which a relying party can trust the binding embodied
   in a certificate. The degree to which such a binding can be trusted
   depends on several factors, e.g., the practices followed by the
   certification authority (CA) in authenticating the subject; 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), and the stated
   responsibilities and liability terms and conditions of the CA (for
   example, warranties, disclaimers of warranties, and limitations of
   liability).

11. IANA Considerations

   None.
