This document updates [RFC6487]. 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]. 2. Update to RFC 6487 [RFC6487] profiles certificates, certificate revocation lists, and certificate signing requests specified in [RFC5280] for use in routing public key infrastructure. [RFC5280] defines an extension to certificates for the listing of policy information (see Section 4.2.1.4). [RFC6487] states in Section 4.8.9: "This extension MUST be present and MUST be marked critical. It MUST include exactly one policy, as specified in the RPKI CP [RFC6484]". This references the CertPolicyId of the sequence allowed in PolicyInformation as defined by [RFC5280]. [RFC5280] also specifies that PolicyInformation may optionally have a sequence of PolicyQualifierInfo objects. [RFC6487] does not specifically allow or disallow these PolicyQualifierInfo objects, although Section 4 also states: "Unless specifically noted as being OPTIONAL, all the fields listed here MUST be present, and any other fields MUST NOT appear in a conforming resource certificate." Newton & Huston Standards Track [Page 2] RFC 7318 RPKI Policy Qualifiers July 2014 Because there is a need for some RPKI Certificate Authorities to include policy qualifiers in their certificates, this document updates Section 4.8.9 of [RFC6487] as follows: OLD: This extension MUST be present and MUST be marked critical. It MUST include exactly one policy, as specified in the RPKI Certificate Policy (CP) [RFC6484]. NEW: This extension MUST be present and MUST be marked critical. It MUST include exactly one policy, as specified in the RPKI CP [RFC6484]. Exactly one policy qualifier MAY be included. If a policy qualifier is included, the policyQualifierId MUST be the Certification Practice Statement (CPS) pointer qualifier type (id-qt-cps). As noted in [RFC5280], Section 4.2.1.4: "Optional qualifiers, which MAY be present, are not expected to change the definition of the policy." In this case, any optional policy qualifier that MAY beShow full document text
