draft-ietf-sidrops-rpki-rsc-11 (RSCs)
Abstract
This document defines a Cryptographic Message Syntax (CMS) protected
content type for use with the Resource Public Key Infrastructure
(RPKI) to carry a general purpose general-purpose listing of checksums (a
'checklist'). The objective is to allow for the creation of an
attestation, termed an
RPKI "RPKI Signed Checklist (RSC), (RSC)", which contains
one or more checksums of arbitrary digital objects (files) that are
signed "with resources",
and which, when with a specific set of Internet Number Resources. When
validated, an RSC confirms that the respective Internet
Resource Holder resource
holder produced the RSC.

1. Introduction
This document defines a Cryptographic Message Syntax (CMS) [RFC5652]
[RFC6268] protected content type for a general purpose general-purpose listing of
checksums (a 'checklist'), for use with the Resource Public Key
Infrastructure (RPKI) [RFC6480]. The protected CMS protected content type is
intended to provide for the creation and validation of an RPKI Signed
Checklist (RSC): (RSC), a checksum listing signed with a specific set of
Internet Number Resources. The objective is to allow for the
creation of an attestation that, when validated, provides a means to
confirm a given Internet
Resource Holder resource holder produced the RSC.
RPKI Signed Checklist (RSC).
Signed Checklists are expected to facilitate inter-domain
business
use-cases which use cases that depend on an ability to verify resource
holdership. RPKI-based validation processes are expected to become
the industry norm for automated Bring Your Own IP (BYOIP) on-boarding
or establishment of physical interconnection interconnections between Autonomous Systems.
Systems (ASes).
The RSC concept borrows heavily from RTA [I-D.ietf-sidrops-rpki-rta], Resource Tagged Attestation
(RTA) [RPKI-RTA], Manifests [RFC9286], and OpenBSD's [signify] utility. signify utility
[signify]. The main difference between an RSC and RTA is that the
RTA profile allows multiple signers to attest a single digital object
through a checksum of its content, while the RSC profile allows a
single signer to attest the content of multiple digital objects. A
single signer profile is considered a simplification for both
implementers and operators.
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. RSC Profile and Distribution
RSC follows the Signed Object Template for the RPKI [RFC6488] with
one exception: because RSCs MUST NOT be distributed through the
global RPKI Repository repository system, the Subject Information Access (SIA)
extension MUST be omitted from the RSC's X.509 End-Entity (EE)
certificate.
What constitutes suitable transport for RSC files is deliberately
unspecified. For example, it might be a USB stick, a web interface
secured with HTTPS, a PGP-signed email, an email signed with Pretty Good Privacy (PGP), a
T-shirt printed with a QR code, or a carrier pigeon.
2.1. RSC End-Entity EE Certificates
The Certification Authority (CA) MUST only sign one RSC with each
End-Entity (EE) Certificate, EE
certificate and MUST generate a new key pair for each new RSC. This form of use
type of the associated EE Certificate certificate is termed a "one-time-use" EE certificate (see
Section 3 of [RFC6487]. [RFC6487]).
3. The RSC ContentType eContentType
The ContentType eContentType for an RSC is defined as rpkiSignedChecklist, id-ct-signedChecklist, with
Object Identifier (OID) 1.2.840.113549.1.9.16.1.48.
This OID MUST appear both within both the eContentType in the
encapContentInfo object as well as and the ContentType signed attribute in the
signerInfo object (see [RFC6488]).
4. The RSC eContent
The content of an RSC indicates that a checklist for arbitrary
digital objects has been signed "with resources". with a specific set of Internet
Number Resources. An RSC is formally defined as: as follows:
RpkiSignedChecklist-2022
{ iso(1) member-body(2) us(840) rsadsi(113549)

END
4.1. version Version
The version number of the RpkiSignedChecklist MUST be 0.
4.2. resources Resources
The resources contained here are the resources used to mark the
attestation,
attestation and MUST be a subset of the set of resources listed by
the EE Certificate certificate carried in the CMS certificates field.
If the asID field is present, it MUST contain an instance of
ConstrainedASIdentifiers.
If the ipAddrBlocks field is present, it MUST contain an instance of
ConstrainedIPAddrBlocks.
At least one of asID or ipAddrBlocks MUST be present.
Each of
ConstrainedASIdentifiers and ConstrainedIPAddrBlocks are specified
such that the resulting DER-encoded data instances are binary
compatible with, respectively, with ASIdentifiers and IPAddrBlocks
defined (defined in [RFC3779].
[RFC3779]), respectively.
Implementations encountering decoding errors whilst attempting to
read DER-encoded data using this specification should be aware of the
possibility that the data may have been encoded using an
implementation intended for use with [RFC3779]. Such data may
contain elements prohibited by the current specification.
Attempting to decode the errored data using the more permissive
specification contained in [RFC3779] may enable implementors to
gather additional context for use when reporting errors to the user.
However, implementations MUST NOT ignore errors resulting from the
more restrictive definitions contained herein: herein; in particular, such
errors MUST cause the validation procedure described in Section 5 to
fail.
4.2.1. ConstrainedASIdentifiers type Type
ConstrainedASIdentifiers is a SEQUENCE, SEQUENCE consisting of a single field
"asnum", itself containing field,
asnum, which in turn contains a SEQUENCE OF one or more ASIdOrRange
instances as defined in [RFC3779].
ConstrainedASIdentifiers is defined such that the resulting DER-
encoded data are binary compatible with ASIdentifiers defined in
[RFC3779].
4.2.2. ConstrainedIPAddrBlocks type Type
ConstrainedIPAddrBlocks is a SEQUENCE OF one or more instances of
ConstrainedIPAddressFamily.
There MUST be only one instance of ConstrainedIPAddressFamily per
unique AFI. Address Family Identifier (AFI).
The elements of ConstrainedIPAddressFamily MUST be ordered by
ascending addressFamily values (treating the octets as unsigned
numbers). Thus, when both IPv4 and IPv6 addresses are specified, the
IPv4 addresses MUST precede the IPv6 addresses (since the IPv4 AFI of
0001 is less than the IPv6 AFI of 0002).
ConstrainedIPAddrBlocks is defined such that the resulting DER-
encoded data are binary compatible with IPAddrBlocks defined in
[RFC3779].
4.2.2.1. ConstrainedIPAddressFamily type Type
4.2.2.1.1. addressFamily field Field
The addressFamily field is an OCTET STRING containing a two-octet
Address Family Identifier (AFI), 2-octet AFI,
in network byte order. Unlike IPAddrBlocks [RFC3779], a third octet
containing a Subsequent Address Family Identifier (SAFI) MUST NOT be
present. AFIs are specified in the Address "Address Family Numbers Numbers" registry
[IANA.ADDRESS-FAMILY-NUMBERS] maintained by IANA.
4.2.2.1.2. addressesOrRanges field Field
The addressesOrRanges element is a SEQUENCE OF one or more
IPAddressOrRange values, as defined in [RFC3779]. The rules for
canonicalization and encoding defined in Section 2.2.3.6 of [RFC3779]
apply to the value of addressesOrRanges.
4.3. digestAlgorithm
The digest algorithm is used to create the message digest of the
attested digital object(s). This algorithm MUST be a hashing
algorithm defined in [RFC7935].
4.4. checkList
This field is a SEQUENCE OF one or more FileNameAndHash values.
There is one FileNameAndHash entry for each digital object referenced
on the Signed Checklist. RSC.
4.4.1. FileNameAndHash
Each FileNameAndHash is an ordered pair of the name of the directory
entry containing the digital object, object and the message digest of the
digital object.
The hash field is mandatory. The value of the hash field is the
calculated message digest of the digital object. The hashing
algorithm is specified in the digestAlgorithm field.
The fileName field is OPTIONAL. This is to allow Signed Checklists RSCs to be used in
a "stand-alone" fashion in which nameless digital objects are
addressed directly through their respective message digest rather
than through a file system abstraction.
If the fileName field is present present, then its value:
* MUST contain only characters specified in the Portable Filename
Character Set as defined in [POSIX].
* MUST be unique with respect to the other FileNameAndHash elements
of checkList for which the fileName field is also present.
Conversely, if the fileName field is omitted, then the value of the
hash field MUST be unique with respect to the other FileNameAndHash
elements of checkList for which the fileName field is also omitted.
5. RSC Validation
Before a Relying Party (RP) can use an RSC to validate a set of
digital objects, the Relying Party RP MUST first validate the RSC. To validate an
RSC, the Relying Party RP MUST perform all the validation checks specified in [RFC6488] (except
[RFC6488], except for checking for the presence of an SIA extension,
which MUST NOT be present in the EE X.509 certificate (see Section 4.8.8.2 of [RFC6487]), and 2). In
addition, the RP MUST perform the following additional RSC-specific validation
steps:
1. The contents of the CMS eContent field MUST conform to all of the
constraints described in Section 4 4, including the constraints
described in Section 4.4.1.
2. If the asID field is present within the contents of the
'resources' resources
field, then the AS Resources identifier delegation extension [RFC3779] MUST
be present in the EE certificate contained in the CMS
certificates field. The AS identifiers present in the eContent
'resources'
resources field MUST be a subset of those present in the
certificate extension. The EE certificate's AS Resources identifier
delegation extension MUST NOT contain "inherit" elements.
3. If the ipAddrBlocks field is present within the contents of the
'resources'
resources field, then the IP Resources address delegation extension
[RFC3779] MUST be present in the EE certificate contained in the
CMS certificates field. The IP addresses present in the eContent
'resources'
resources field MUST be a subset of those present in the
certificate extension. The EE certificate's IP Resources address
delegation extension MUST NOT contain "inherit" elements.
6. Verifying files Files or data using Data Using RSC
To verify a set of digital objects with an RSC:
* The RSC MUST be validated according to the procedure described in
Section 5. If the RSC cannot be validated, verification MUST
fail. This error SHOULD be reported to the user.
* For every digital object to be verified:
1. If the verification procedure is provided with a file name filename for
the object being verified (e.g. (e.g., because the user has provided
a file system path from which to read the object) object), then
verification SHOULD proceed in "filename-aware" mode.
Otherwise, verification SHOULD proceed in "filename-unaware"
mode.
Implementations MAY provide an option to override the
verification mode, for example example, to ignore the fact that the
object is to be read from a file.
2. The message digest MUST be computed from the file contents or
data using the digest algorithm specified in the
digestAlgorithm field of the RSC.
3. The digest computed in step Step 2 MUST be compared to the value
appearing in the hash field of all FileNameAndHash elements of
the checkList field of the RSC.
One or more FileNameAndHash elements MUST be found with a
matching hash value, otherwise value; otherwise, verification MUST fail fail, and
the error SHOULD be reported to the user.
4. If the mode selected in step Step 1 is "filename-aware" "filename-aware", then
exactly one of the FileNameAndHash elements matched in step Step 3
MUST contain a fileName field value exactly matching the file
name
filename of the object being verified.
Alternatively, if the mode selected in step Step 1 is "filename-
unaware"
unaware", then exactly one of the FileNameAndHash elements
matched in step Step 3 MUST have the fileName field omitted.
Otherwise, verification MUST fail, and the error SHOULD be
reported to the user.
Note that in the above procedure, not all elements of checkList
necessarily need be used. That is, it is not an error if the length
of checkList is greater than the size of the set of digital objects
to be verified. However, in this situation, implementations SHOULD
issue a warning to the user, allowing for corrective action to be
taken if necessary.
7. Operational Considerations
When creating digital objects of a plain-text nature (such as ASCII,
UTF-8, HTML, Javascript, XML, etc.) and XML), converting such objects into a
lossless compressed form is RECOMMENDED. Distributing plain-text
objects within a compression envelope (such as GZIP [RFC1952]) might
help avoid unexpected canonicalization at intermediate systems (which
in turn would lead to checksum verification errors). Validator
implementations are expected to treat a checksummed digital object as
a string of arbitrary single octets.
If a fileName field is present, but no digital object within the set
of to-be-verified digital objects has a filename that matches the
content of that field, a validator implementation SHOULD compare the
message digest of each digital object to the value from the hash
field of the associated FileNameAndHash and report matches to the
user for further consideration; or report an error indicating no file
by that name exists. consideration.
8. Security Considerations
Relying parties
RPs are hereby warned that the data in a RPKI Signed
Checklist an RSC is self-asserted. When
determining the meaning of any data contained in an RPKI Signed Checklist, Relying Parties RSC, RPs MUST NOT
make any assumptions about the signer beyond the fact that it had
sufficient control of the issuing CA to create the object. These
data have not been verified by the Certificate Authority (CA) that
issued the CA certificate to the entity that issued the EE
Certificate
certificate used to validate the Signed Checklist. RSC.
RPKI Certificates certificates are not bound to real world identities, real-world identities; see
[RFC9255] for an elaboration. Relying Parties RPs can only associate
real world real-world
entities to Internet Number Resources by additionally consulting an
exogenous authority. Signed Checklists RSCs are a tool to communicate assertions 'signed
signed with Internet Number Resources', Resources and do not
about communicate any
other aspect of the resource holder's business operations operations, such as
the identity of the resource holder itself.
RSC objects are not distributed through the RPKI Repository repository system.
From this, it follows that third parties who do not have a copy of a
given RSC, RSC may not be aware of the existence of that RSC. Since RSC
objects use EE Certificates, certificates but all other currently defined types of
RPKI object profiles are published in public CA repositories, an
observer may infer from discrepancies in the Repository repository that RSC
object(s) may exist. For example, if a CA does not use random serial
numbers for Certificates, certificates, an observer could detect gaps between the
serial numbers of the published EE Certificates. certificates. Similarly, if the
CA includes a serial number on a CRL Certificate Revocation List (CRL)
that does not match any published object, an observer could postulate
that an RSC EE Certificate certificate was revoked.
Conversely, a gap in serial numbers does not imply that an RSC
exists. Nor does an arbitrary (to the RP unknown) serial presence in a CRL of a serial number unknown to
the RP imply an RSC object exists: the implicitly referenced object
might not be an RSC, it might have never been published, or was it may
have been revoked before it was visible to RPs. In general, it is
not possible to confidently infer the existence or non-existence of
RSCs from the
Repository repository state without access to a given RSC.
While a one-time-use EE Certificate certificate must only be used to generate and
sign a single RSC object, CAs technically are not restricted from
generating and signing multiple different RSC objects with a single
keypair.
key pair. Any RSC objects sharing the same EE Certificate can not certificate cannot be
revoked individually.
