JOSE signed Voucher Artifacts for Bootstrapping Protocols

Abstract

This document describes a serialiation of the RFC8366 voucher format to a JSON format is then signed using the JSON Object Signing and Encryption mechanism described in RFC7515.¶

In addition to explaining how the format is created, MIME types are registered and examples are provided.¶

1. Introduction

[RFC8366] describes a voucher artifact used in [RFC8995] and [RFC8572] 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].¶

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.¶

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. This document restricts itself to the JWS Compact Serialization (JWT) format.¶

The [RFC8366] JSON structure consists of a nested map, the outer part of which is:¶

{ "ietf-voucher:voucher" : { ..some items }}

this is considered the JSON payload as described in [RFC7515] section 3.¶

The JSON Compact Serialization is examplained in section 3.1 or section 7.1, and works out to:¶

      BASE64URL(UTF8(JWS Protected Header)) || '.' ||
      BASE64URL(JWS Payload) || '.' ||
      BASE64URL(JWS Signature)

Note that this results in a long base64 content (with two interspersed dots). The content is transmitted within the HTTPS session in this base64 format, even though HTTP can accomodate 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 [RFC8995] 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 [RFC8995] section 5.5.2.¶

4. Privacy Considerations

The Voucher Request reveals the IDevID of the system that is onboarding.¶

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 [RFC8995] section 10.2.¶

5. Security Considerations

The issues of how [RFC8366] vouchers are used in a [RFC8995] system is addressed in¶

6. IANA Considerations

6.1. Media-Type Registry

This section registers the the 'application/voucher-jwt+json' in the "Media Types" registry.¶

6.1.1. application/voucher-jose+json

Type name:  application
Subtype name:  voucher-jwt+json
Required parameters:  none
Optional parameters:  none
Encoding considerations:  JWT+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
