        This document specifies a Canonical Cache Representation (CCR) content type for use with the Resource Public Key Infrastructure (RPKI).
        CCR is a DER-encoded data interchange format which can be used to represent various aspects of the state of a validated cache at a particular point in time.
        The CCR profile is a compact and versatile format well-suited for a diverse set of applications such as audit trail keeping, validated payload dissemination, and analytics pipelines.

      <t>
        This document specifies a Canonical Cache Representation (CCR) content type for use with the Resource Public Key Infrastructure (RPKI).
        A validated cache contains all RPKI objects that the Relying Party (RP) has verified to be valid according to the rules for validation (see <xref target="RFC6487"/>, <xref target="RFC6488"/>, <xref target="RFC9286"/>).
        CCR is a data interchange format using Distinguished Encoding Rules (DER, <xref target="X.690"/>) which can be used to represent various aspects of the state of a validated cache at a particular point in time.
        The CCR profile is a compact and versatile format well-suited for a diverse set of applications such as audit record keeping, validated payload dissemination, and analytics pipelines.
      </t>
      <t>
         The format was primarily designed to support comparative analysis of uniformities and differences among multiple RP instances using different RPKI transport protocols (such as <xref target="RFC5781"/>, <xref target="RFC8182"/>, and <xref target="I-D.spaghetti-sidrops-rpki-erik-protocol"/>).

        </t>
        <t>
          Each state aspect generally consists of a sequence of details extracted from RPKI Objects of a specific type, along with a digest computed by hashing the aforementioned DER-encoded sequence, optionally including some metadata.

          <name>ManifestState</name>
          <t>
            An instance of <tt>ManifestState</tt> represents the set of valid, current Manifests (<xref target="RFC9286"/>) in the cache.
            It contains three fields: <tt>mis</tt>, <tt>mostRecentUpdate</tt>, and <tt>hash</tt>.

              The <tt>mis</tt> field contains a SEQUENCE of <tt>ManifestInstance</tt>.
              There is one <tt>ManifestInstance</tt> for each current manifest.
              A manifest is nominally current until the time specified in nextUpdate or until a manifest is issued with a greater manifestNumber, whichever comes first (see <xref target="RFC9286" section="4.2.1"/>).
            </t>
            <t>
              A <tt>ManifestInstance</tt> is a structure consisting of the following fields:

            </dl>
            <t>
              The <tt>subordinates</tt> field represents the keypairs associated with the set of non-revoked, non-expired, validly signed resource certificates subordinate to the manifest issuer.
              Each <tt>SubjectKeyIdentifier</tt> is the 160-bit SHA-1 hash of the value of the DER-encoded ASN.1 bit string of the resource certificate's Subject Public Key, as described in <xref target="RFC6487" section="4.8.2"/>.
              The sequence elements of the <tt>subordinates</tt> field <bcp14>MUST</bcp14> be sorted in ascending order by interpreting each <tt>SubjectKeyIdentifier</tt> value as an unsigned 160-bit integer and <bcp14>MUST</bcp14> be unique with respect to each other.

              <t>To help reduce well-known threats against BGP including prefix mis- announcing and monkey-in-the-middle attacks, one of the security requirements is the ability to validate the origination Autonomous System (AS) of BGP routes. More specifically, one needs to validate that the AS number claiming to originate an address prefix (as derived from the AS_PATH attribute of the BGP route) is in fact authorized by the prefix holder to do so. This document describes a simple validation mechanism to partially satisfy this requirement. [STANDARDS-TRACK]</t>

              <t>This document defines a "manifest" for use in the Resource Public Key Infrastructure (RPKI). A manifest is a signed object (file) that contains a listing of all the signed objects (files) in the repository publication point (directory) associated with an authority responsible for publishing in the repository. For each certificate, Certificate Revocation List (CRL), or other type of signed objects issued by the authority that are published at this repository publication point, the manifest contains both the name of the file containing the object and a hash of the file content. Manifests are intended to enable a relying party (RP) to detect certain forms of attacks against a repository. Specifically, if an RP checks a manifest's contents against the signed objects retrieved from a repository publication point, then the RP can detect replay attacks, and unauthorized in-flight modification or deletion of signed objects. This document obsoletes RFC 6486.</t>

            <abstract>
              <t>In the Resource Public Key Infrastructure (RPKI), Certificate Authorities (CAs) publish certificates, including end-entity certificates, Certificate Revocation Lists (CRLs), and RPKI signed objects to repositories. Relying Parties retrieve the published information from those repositories. This document specifies a new RPKI Repository Delta Protocol (RRDP) for this purpose. RRDP was specifically designed for scaling. It relies on an Update Notification File which lists the current Snapshot and Delta Files that can be retrieved using HTTPS (HTTP over Transport Layer Security (TLS)), and it enables the use of Content Distribution Networks (CDNs) or other caching infrastructures for the retrieval of these files.</t>

              <t>This document describes BGPsec, an extension to the Border Gateway Protocol (BGP) that provides security for the path of Autonomous Systems (ASes) through which a BGP UPDATE message passes. BGPsec is implemented via an optional non-transitive BGP path attribute that carries digital signatures produced by each AS that propagates the UPDATE message. The digital signatures provide confidence that every AS on the path of ASes listed in the UPDATE message has explicitly authorized the advertisement of the route.</t>

      <name>Implementation status</name>
      <t>
        This section records the status of known implementations of the protocol defined by this specification at the time of posting of this Internet-Draft, and is based on a proposal described in RFC 7942.
        The description of implementations in this section is intended to assist the IETF in its decision processes in progressing drafts to RFCs.
        Please note that the listing of any individual implementation here does not imply endorsement by the IETF.
        Furthermore, no effort has been spent to verify the information presented here that was supplied by IETF contributors.
        This is not intended as, and must not be construed to be, a catalog of available implementations or their features.
        Readers are advised to note that other implementations may exist.
      </t>
      <t>
        According to RFC 7942, "this will allow reviewers and working groups to assign due consideration to documents that have the benefit of running code, which may serve as evidence of valuable experimentation and feedback that have made the implemented protocols more mature.
        It is up to the individual working groups to use this information as they see fit".
