Expires 4 February 2024 [Page 2] Internet-Draft A Profile for Route Origin Authorization August 2023 1. Introduction The primary purpose of the Resource Public Key Infrastructure (RPKI) is to improve routing security. (See [RFC6480] for more information.) As part of this system, a mechanism is needed to allow entities to verify that an AS has been given permission by an IP address block holder to advertise routes to one or more prefixes within that block. A ROA provides this function. The ROA makes use of the template for RPKI digitally signed objects [RFC6488], which defines a Crytopgraphic Message Syntax (CMS) [RFC5652] wrapper for the ROA content as well as a generic validation procedure for RPKI signed objects. Therefore, to complete the specification of the ROA (see Section 4 of [RFC6488]), this document defines: * The OID that identifies the signed object as being a ROA. (This OID appears within the eContentType in the encapContentInfo object as well as the content-type signed attribute in the signerInfo object). * The ASN.1 syntax for the ROA eContent. (This is the payload that specifies the AS being authorized to originate routes as well as the prefixes to which the AS may originate routes.) The ROA eContent is ASN.1 encoded using the Distinguished Encoding Rules (DER) [X.690]. * Additional steps required to validate ROAs (in addition to the validation steps specified in [RFC6488]). 1.1. Changes from RFC6482 This section summarizes the significant changes between [RFC6482] and the profile described in this document. * Clarified the requirements for the IP Addresses and AS Identifiers X.509 certificate extensions. * Strengthened the ASN.1 formal notation and definitions. * Incorporated Errata for RFC 6488. * Added an example ROA eContent payload and an ROA. * Specified a canonicalization procedure for the content of ipAddrBlocks. Snijders, et al. Expires 4 February 2024 [Page 3] Internet-Draft A Profile for Route Origin Authorization August 2023 2. Related Work It is assumed that the reader is familiar with the terms and concepts described in "Internet X.509 Public Key Infrastructure Certificate and Certificate Revocation List (CRL) Profile" [RFC5280] and "X.509 Extensions for IP Addresses and AS Identifiers" [RFC3779]. Additionally, this document makes use of the RPKI signed object profile [RFC6488]; thus, familiarity with that document is assumed. Note that the RPKI signed object profile makes use of certificates adhering to the RPKI Resource Certificate Profile [RFC6487]; thus, familiarly with that profile is also assumed. 3. The ROA ContentType The content-type for a ROA is defined as routeOriginAuthz and has the numerical value of 1.2.840.113549.1.9.16.1.24. This OID MUST appear both within the eContentType in the encapContentInfo object as well as the ContentType signed attribute in the signerInfo object (see [RFC6488]). 4. The ROA eContent The content of a ROA identifies a single AS that has been authorized by the address space holder to originate routes and a list of one or more IP address prefixes that will be advertised. If the address space holder needs to authorize multiple ASes to advertise the same set of address prefixes, the holder issues multiple ROAs, one per AS number. A ROA is formally defined as: RPKI-ROA-2023 { iso(1) member-body(2) us(840) rsadsi(113549) pkcs(1) pkcs9(9) smime(16) mod(0) id-mod-rpkiROA-2023(TBD) } DEFINITIONS EXPLICIT TAGS ::= BEGIN IMPORTS CONTENT-TYPE FROM CryptographicMessageSyntax-2010 -- in [RFC6268] { iso(1) member-body(2) us(840) rsadsi(113549) pkcs(1) pkcs-9(9) smime(16) modules(0) id-mod-cms-2009(58) } ; ct-routeOriginAttestation CONTENT-TYPE ::= { TYPE RouteOriginAttestation IDENTIFIED BY id-ct-routeOriginAuthz } id-ct-routeOriginAuthz OBJECT IDENTIFIER ::= Snijders, et al.

Element version The version number of the RouteOriginAttestation MUST be 0. 4.2. Element asID The asID element contains the AS number that is authorized to originate routes to the given IP address prefixes. Snijders, et al. Expires 4 February 2024 [Page 5] Internet-Draft A Profile for Route Origin Authorization August 2023 4.3. Element ipAddrBlocks The ipAddrBlocks element encodes the set of IP address prefixes to which the AS is authorized to originate routes. Note that the syntax here is more restrictive than that used in the IP Address Delegation extension defined in [RFC3779]. That extension can represent arbitrary address ranges, whereas ROAs need to represent only IP prefixes. 4.3.1. Type ROAIPAddressFamily Within the ROAIPAddressFamily structure, the addressFamily element contains the Address Family Identifier (AFI) of an IP address family. This specification only supports IPv4 and IPv6, therefore addressFamily MUST be either 0001 or 0002. IPv4 prefixes MUST NOT appear as IPv4-Mapped IPv6 Addresses (section 2.5.5.2 of [RFC4291]). There MUST be only one instance of ROAIPAddressFamily per unique AFI in the ROA. Thus, the ROAIPAddressFamily structure MUST NOT appear more than twice. The addresses element represents IP prefixes as a sequence of type ROAIPAddress. 4.3.2. Type ROAIPAddress A ROAIPAddress structure is a sequence containing an address element of type IPAddress and an optional maxLength element of type INTEGER. 4.3.2.1. Element address The address element represents a single IP address prefix. See section 2.2.3.8 of [RFC3779] for more details on type IPAddress. 4.3.2.2. Element maxLength When present, the maxLength specifies the maximum length of the IP address prefix that the AS is authorized to advertise. The maxLength element SHOULD NOT be encoded if the maximum length is equal to the prefix length. If present, the maxLength MUST be: * an integer greater than or equal to the length of the accompanying prefix, and Snijders, et al. Expires 4 February 2024 [Page 6] Internet-Draft A Profile for Route Origin Authorization August 2023 * less than or equal to the maximum length (in bits) of an IP address in the applicable address family: 32 in case of IPv4 and 128 in case of IPv6. For example, if the IP address prefix is 203.0.113.0/24 and the maxLength is 26, the AS is authorized to advertise any more specific prefix with a maximum length of 26. In this example, the AS would be authorized to advertise 203.0.113.0/24, 203.0.113.128/25, or 203.0.113.192/26; but not 203.0.113.0/27. See [RFC9319] for more information on the use of maxLength. When the maxLength is not present, the AS is only authorized to advertise the exact prefix specified in the ROAIPAddress' address element. 4.3.2.3. Note on overlapping or superfluous information encoding Note that a valid ROA may contain an IP address prefix (within a ROAIPAddress element) that is encompassed by another IP address prefix (within a separate ROAIPAddress element). For example, a ROA may contain the prefix 203.0.113.0/24 with maxLength 26, as well as the prefix 203.0.113.0/28 with maxLength 28. This ROA would authorize the indicated AS to advertise any prefix beginning with 203.0.113 with a minimum length of 24 and a maximum length of 26, as well as the specific prefix 203.0.113.0/28. Additionally, a ROA MAY contain two ROAIPAddress elements, where the IP address prefix is identical in both cases. However, this is NOT RECOMMENDED as, in such a case, the ROAIPAddress with the shorter maxLength grants no additional privileges to the indicated AS and thus can be omitted without changing the meaning of the ROA. 4.3.3. Canonical form for ipAddrBlocks As the data structure described by the ROA ASN.1 module allows for many different ways to represent the same set of IP address information, a canonical form is defined such that every set of IP address information has a unique representation. In order to produce and verify this canonical form, the process described in this section SHOULD be used to ensure information elements are unique with respect to one another and sorted in ascending order. This canonicalization procedure builds upon the canonicalization procedure specified in section 2.2.3.6 of [RFC3779]. In order to semantically compare, sort, and deduplicate the contents of the ipAddrBlocks field, each ROAIPAddress element is mapped to an abstract data element composed of four integer values: Snijders, et al. Expires 4 February 2024 [Page 7] Internet-Draft A Profile for Route Origin Authorization August 2023 afi The AFI value appearing in the addressFamily field of the containing ROAIPAddressFamily as an integer. addr The first IP address of the IP prefix appearing in the ROAIPAddress address field, as 32-bit (IPv4) or 128-bit (IPv6) integer value. plen The prefix length of the IP prefix appearing in the ROAIPAddress address field as an integer value. mlen The value appearing in the maxLength field of the ROAIPAddress, if present, otherwise the above prefix length value. Thus, the equality or relative order of two ROAIPAddress elements can be tested by comparing their abstract representations. 4.3.3.1. Comparator 1. Data elements with a lower afi value precede data elements with a higher afi value. 2. Data elements with a lower addr value precede data elements with a higher addr value. 3. Data elements with a lower plen value precede data elements with a higher plen value. 4. Data elements with a lower mlen value precede data elements with a higher mlen value. Data elements for which all four values compare equal are duplicates of one another. 4.3.3.2. Example implementations A sorting implementation [roasort-c] in ISO/IEC 9899:1999 ("ANSI C99"). A sorting implementation [roasort-rs] in Rust 2021 Edition. 5. ROA Validation Before a relying party can use a ROA to validate a routing announcement, the relying party MUST first validate the ROA. To validate a ROA, the relying party MUST perform all the validation checks specified in [RFC6488] as well as the following additional ROA-specific validation steps. Snijders, et al. Expires 4 February 2024 [Page 8] Internet-Draft A Profile for Route Origin Authorization August 2023 * The IP Address Delegation extension [RFC3779] is present in the end-entity (EE) certificate (contained within the ROA), and every IP address prefix in the ROA payload is contained within the set of IP addresses specified by the EE certificate's IP Address Delegation extension. * The EE certificate's IP Address Delegation extension MUST NOT contain "inherit" elements described in [RFC3779]. * The Autonomous System Identifier Delegation Extension described in [RFC3779] is not used in Route Origin Authorizations and MUST NOT be present in the EE certificate. 6. Security Considerations There is no assumption of confidentiality for the data in a ROA; it is anticipated that ROAs will be stored in repositories that are accessible to all ISPs, and perhaps to all Internet users. There is no explicit authentication associated with a ROA, since the PKI used for ROA validation provides authorization but not authentication. Although the ROA is a signed, application-layer object, there is no intent to convey non-repudiation via a ROA. The purpose of a ROA is to convey authorization for an AS to originate a route to the prefix(es) in the ROA. Thus, the integrity of a ROA MUST be established. The ROA specification makes use of the RPKI signed object format; thus, all security considerations in [RFC6488] also apply to ROAs. Additionally, the signed object profile uses the CMS signed message format for integrity; thus, ROAs inherit all security considerations associated with that data structure. The right of the ROA signer to authorize the target AS to originate routes to the prefix(es) is established through use of the address space and AS number PKI described in [RFC6480]. Specifically, one MUST verify the signature on the ROA using an X.509 certificate issued under this PKI, and check that the prefix(es) in the ROA are contained within those in the certificate's IP Address Delegation Extension. 7.
