Table of Contents

1. Introduction

The ADEM Core Specification specifies how a set of tokens, encoded as JSON Web Signatures (JWSs) [RFC7515], can be used as a digital emblem to signal that digital assets enjoy specific protections under International Humanitarian Law (IHL). This document describes a DNS-based distribution and discovery for ADEM tokens.

2. Conventions and Definitions

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. DNS Distribution

Given a set of tokens containing exactly one emblem and zero or more associated endorsements, issuers can distribute this set via DNS TXT records [RFC1035], as follows.

For each such set, issuers MAY choose a unique identifier string. If multiple sets of tokens are associated with a given domain name, issuers SHOULD choose such a string.

Each token is distributed as its own TXT record, which includes a key and a value. The value encodes the token in JWT compact serialization.

Each record's key MUST be formatted as:

key := "adem" [ "-" identifier ]

identifier := CHARACTER-NO-HYPEN+

record := key "=" value

CHARACTER-NO-HYPEN is any printable ASCII character as specified in [RFC0020] except for "-". If present, identifier MUST coincide with the string identifying the token's set.

4. Security Considerations

5. IANA Considerations

This document has no IANA actions.
