JWS signed Voucher Artifacts for Bootstrapping Protocols
draft-richardson-anima-jose-voucher-02
Abstract
RFC8366 defines a digital artifact called voucher as a YANG-defined
JSON document that has been signed using a Cryptographic Message
Syntax (CMS) structure. This memo introduces a variant of the
voucher structure in which CMS is replaced by the JSON Object Signing
and Encryption (JOSE) mechanism described in RFC7515 to better
support use-cases in which JOSE is preferred over CMS.
In addition to explaining how the format is created, MIME types are
registered and examples are provided.

1. Introduction
"A Voucher Artifact for Bootstrapping Protocols", [RFC8366] describes
a voucher artifact used in "Bootstrapping Remote Secure Key
Infrastructure" [BRSKI] and "Secure Zero Touch Provisioning" [SZTP]
to transfer ownership of a device to from a manufacturer to an owner.
That document defines the base YANG module, and also the initial
serialization to JSON [RFC8259], with a signature provided by
[RFC5652].
Other work, [I-D.ietf-anima-constrained-voucher] provides a mapping
of the YANG to CBOR [RFC8949] with a signature format of COSE
[RFC8812].
This document provides an equivalent mapping of JSON format with the
signature format in JOSE format [RFC7515]. The encoding specified in
this document is required for [I-D.ietf-anima-brski-async-enroll] and
may be required and/or preferred in other use-cases, for example when
JOSE is already used in other parts of the use-case, but CMS is not.

Internet-Draft JWS-voucher July 2021
This document does not extend the YANG definition of [RFC8366] at
all, but accepts that other efforts such as
[I-D.richardson-anima-voucher-delegation],
[I-D.friel-anima-brski-cloud], and
[I-D.ietf-anima-brski-async-enroll] do. This document supports
signing any of the extended schemas defined in those documents and
any new documents that may appear after this one.
With the availability of different encoded vouchers, it is up to an
industry specific application statement to indicate/decide which
voucher format is to be used. There is no provision across the
different voucher formats that a receiver could safely recognize
which format it uses unless additional context is provided. For
example, [BRSKI] provides this context via the MIME-Type for the
voucher payload.
This document should be considered an Update to [RFC8366] in the
category of "See Also" as per [I-D.kuehlewind-update-tag].
2. Terminology
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.
3. JSON Web Signatures
[RFC7515] defines two serializations: the JWS Compact Serialization
and the JWS JSON Serialization. The two serializations are mostly
equivalent, and the JWS Compact Serialization (JWT) format has better
library support in web frameworks, so this document restricts itself
to that choice.
The [RFC8366] JSON structure consists of a nested map, the outer part
of which is:
{ "ietf-voucher:voucher" : { some inner items }}
this is considered the JSON payload as described in [RFC7515] section
3.
The JSON Compact Serialization is explained in section 3.1 or section
7.1, and works out to:
Richardson & Werner Expires 26 January 2022 [Page 3]
Internet-Draft JWS-voucher July 2021
BASE64URL(UTF8(JWS Protected Header)) || '.' ||
BASE64URL(JWS Payload) || '.' ||
BASE64URL(JWS Signature)
Note that this results in a long base64 content (with two
interspersed dots). When using HTTPS, the voucher is transmitted in
base64 format, even though HTTP can accommodate binary content. This
is done to be most convenient for available JWT libraries, and for
humans who are debugging.
There are a number of attributes. They are:
3.1. Unprotected Header
There is no unprotected header in the Compact Serialization format.
3.2. Protected Header
The standard "typ" and "alg" values described in [RFC7515] are
expected in the protected headers.
It remains to be determined (XXX), what values, if any, should go
into the "typ" header, as in the [BRSKI] use cases, there are
additional HTTP MIME type headers to indicate content types.
The "alg" should contain the algorithm type such as "ES256".
If PKIX [RFC5280] format certificates are used then the [RFC7515]
section 4.1.6 "x5c" certificate chain SHOULD be used to contain the
certificate and chain. Vouchers will often need all certificates in
the chain, including what would be considered the trust anchor
certificate because intermediate devices (such as the Registrar) may
need to audit the artifact, or end systems may need to pin a trust
anchor for future operations. This is consistent with [BRSKI]
section 5.5.2.
4. Privacy Considerations
The Voucher Request reveals the IDevID of the system that is on-
boarding.
This request occurs over HTTPS, however the Pledge to Registrar
transaction is over a provisional TLS session, and it is subject to
disclosure via by a Dolev-Yao attacker (a "malicious
messenger")[onpath]. This is explained in [BRSKI] section 10.2.
The use of a JWS header brings no new privacy considerations.

5. Security Considerations
The issues of how [RFC8366] vouchers are used in a [BRSKI] system is
addressed in section 11 of that document. This document does not
change any of those issues, it just changes the signature technology
used for vouchers and voucher requests.
[SZTP] section 9 deals with voucher use in Secure Zero Touch
Provisioning, and this document also makes no changes to security.
6. IANA Considerations
6.1. Media-Type Registry
This section registers the 'application/voucher-jws+json' in the
"Media Types" registry.
6.1.1. application/voucher-jws+json
Type name: application
Subtype name: voucher-jwt+json
Required parameters: none
Optional parameters: none
Encoding considerations: JWS+JSON vouchers are JOSE objects
signed with one signer.
Security considerations: See Security Considerations, Section
Interoperability considerations: The format is designed to be
broadly interoperable.
Published specification: THIS RFC.
Applications that use this media type: ANIMA, 6tisch, and other
zero-touch imprinting systems

A.2. Example Parboiled Voucher Request (from Registrar to MASA)
The term parboiled refers to food which is partially cooked. In
[BRSKI], the term refers to a voucher-request which has been received
by the Registrar, and then has been processed by the Registrar
("cooked"), and is now being forwarded to the MASA.
Richardson & Werner Expires 26 January 2022 [Page 9]
Internet-Draft JWS-voucher July 2021
The following is an example request sent from the Registrar to the
MASA. This example is from the Siemens reference Registrar system.
Note that the previous voucher request can be seen in the payload as
"prior-signed-voucher-request".
