1. Introduction

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 [RFC6487], [RFC6488], [RFC9286]). CCR is a data interchange format using Distinguished Encoding Rules (DER, [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.

The format was primarily designed to support comparative analysis of uniformities and differences among multiple RP instances using different RPKI transport protocols (such as [RFC5781], [RFC8182], and [I-D.ietf-sidrops-rpki-erik-protocol]).

1.1. Requirements Language

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here.

2. The Canonical Cache Representation content type

The content of a CCR file is an instance of ContentInfo.

The contentType for a CCR is defined as id-ct-rpkiCanonicalCacheRepresentation, with Object Identifier (OID) 1.2.840.113549.1.9.16.1.54.

The content is an instance of RpkiCanonicalCacheRepresentation.

3. The Canonical Cache Representation content

The content of a Canonical Cache Representation is formally defined as follows:

3.1. version

The version field contains the format version for the RpkiCanonicalCacheRepresentation structure, in this version of the specification it MUST be 0.

3.2. hashAlg

The hashAlg field specifies the algorithm used to construct the message digests. This profile uses SHA-256 [SHS], therefore the OID MUST be 2.16.840.1.101.3.4.2.1.

3.3. producedAt

The producedAt field contains a GeneralizedTime and indicates the moment in time the CCR was generated.

3.4. State aspect fields

Each CCR contains one or more fields representing particular aspects of the cache's state. Implementers should note the ellipsis extension marker in the RpkiCanonicalCacheRepresentation ASN.1 notation and anticipate future changes as new signed object types are standardized.

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.

3.4.1. ManifestState

An instance of ManifestState represents the set of valid, current Manifests ([RFC9286]) in the cache. It contains three fields: mis, mostRecentUpdate, and hash.

3.4.1.1. ManifestInstance

The mis field contains a SEQUENCE of ManifestInstance. There is one ManifestInstance 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 Section 4.2.1 of [RFC9286]).

A ManifestInstance is a structure consisting of the following fields:

hash
the hash of the represented DER-encoded manifest object
size
the size of the represented DER-encoded manifest object
aki
the manifest issuer's key identifier
manifestNumber
the manifest number contained within the manifest's eContent field
thisUpdate
the thisUpdate contained within the manifest's eContent field
locations
a sequence of AccessDescription instances from the manifest's End-Entity certificate's Subject Information Access extension
subordinates
a optional non-empty SEQUENCE of SubjectKeyIdentifier

The subordinates field represents the keypairs associated with the set of non-revoked, non-expired, validly signed, certification authority (CA) resource certificates subordinate to the manifest issuer. Each SubjectKeyIdentifier 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 Section 4.8.2 of [RFC6487]. The sequence elements of the subordinates field MUST be sorted in ascending order by interpreting each SubjectKeyIdentifier value as an unsigned 160-bit integer and MUST be unique with respect to each other.

The sequence elements in the mis field MUST be sorted in ascending order by hash value contained in each instance of ManifestInstance and MUST be unique with respect to the other instances of ManifestInstance.

3.4.1.2. mostRecentUpdate

The mostRecentUpdate is a metadata field which contains the most recent thisUpdate amongst all current manifests represented by the ManifestInstance structures. If the mis field contains an empty sequence, the mostRecentUpdate MUST be set to the POSIX Epoch ("19700101000000Z").

3.4.1.3. hash

The hash field contains a message digest computed using the mis value (encoded in DER format) as input message.

3.4.2. ROAPayloadState

An instance of ROAPayloadState contains a field named rps which represents the current set of Validated ROA Payloads (Section 2 of [RFC6811]) encoded as a SEQUENCE of ROAPayloadSet instances.

The ROAPayloadSet structure is modeled after the RouteOriginAttestation (Section 4 of [RFC9582]). The asID value in each instance of ROAPayloadSet MUST be unique with respect to other instances of ROAPayloadSet. The contents of the ipAddrBlocks field MUST appear in canonical form and ordered as defined in Section 4.3.3 of [RFC9582].

The hash field contains a message digest computed using the rps value (encoded in DER format) as input message.

3.4.3. ASPAPayloadState

An instance of ASPAPayloadState contains an aps field which represents the current set of deduplicated and merged ASPA payloads ([I-D.ietf-sidrops-aspa-profile]) ordered by ascending customerASID value encoded as a SEQUENCE of ASPAPayloadSet instances. The customerASID value in each instance of ASPAPayloadSet MUST be unique with respect to other instances of ASPAPayloadSet.

The ASPAPayloadSet structure is modeled after the ProviderASSet (Section 3.3 of [I-D.ietf-sidrops-aspa-profile]).

The hash field contains a message digest computed using the aps value (encoded in DER format) as input message.

3.4.4. TrustAnchorState

An instance of TrustAnchorState represents the set of valid Trust Anchor (TA) Certification Authority (CA) resource certificates used by the relying party when producing the CCR.

Each SubjectKeyIdentifier is the 160-bit SHA-1 hash of the value of the DER-encoded ASN.1 bit string of the TA's Subject Public Key, as described in Section 4.8.2 of [RFC6487]. The skis field contains a sequence of Subject Key Identifiers (SKI) sorted in ascending order by interpreting the SKI value as an unsigned 160-bit integer.

The hash field contains a message digest computed using the skis value (encoded in DER format) as input message.

3.4.5. RouterKeyState

An instance of RouterKeyState contains an rksets field which represents the current set of valid BGPsec Router Keys [RFC8205] encoded as a SEQUENCE of RouterKeySet instances. The asID value in each instance of RouterKeySet MUST be unique with respect to other instances of RouterKeySet. Instances of RouterKeySet are sorted by ascending value of asID. Instances of RouterKey are sorted by ascending value of ski by interpreting the SKI value as an unsigned 160-bit integer.

The hash field contains a message digest computed using the rks value (encoded in DER format) as input message.

4. Operational Considerations

Comparing the ManifestState mostRecentUpdate timestamp value with the producedAt timestamp might help offer insight into the timing and propagation delays of the RPKI supply chain.

Given the absence of public keys and fairly repetitive content in RPKI AccessDescription instances, it should be noted CCR content compresses well.

4.1. Verifying CCR file integrity

The integrity of a CCR object can be checked by confirming whether the hash values embedded inside state aspects match the computed hash value of the respective state aspect payload structure.

5. Security Considerations

CCR objects are not signed objects.

Appendix C. Implementation status

This section is to be removed before publishing as an RFC.

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.

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".

  • Example .ccr files were created by Job Snijders. A current example CCR (regenerated every few minutes) is available here: https://console.rpki-client.org/rpki.ccr
  • A CCR serializer and deserializer implementation based on [rpki-client] was provided by Job Snijders and Theo Buehler.
  • Another CCR serializer and deserializer implementation based on [rpkitouch] was provided by Job Snijders.
