   Automated Certificate Management Environment (ACME) Delay-Tolerant
             Networking (DTN) Node ID Validation Extension
                      draft-ietf-acme-dtnnodeid-00

Abstract

   This document specifies an extension to the Automated Certificate
   Management Environment (ACME) protocol which allows an ACME server to
   validate the Delay-Tolerant Networking (DTN) Node ID for an ACME
   client.  The DTN Node ID is encoded as a certificate Subject
   Alternative Name (SAN) of type Uniform Resource Identifier (URI) and
   ACME Identifier type "uri".

1.  Introduction

   Although the original purpose of the Automatic Certificate Management
   Environment (ACME) [RFC8555] was to allow Public Key Infrastructure
   Using X.509 (PKIX) certificate authorities to validate network domain
   names of clients, the same mechanism can be used to validate any of
   the subject claims supported by the PKIX profile [RFC5280].
