This document specifies an extension to the Automated Certificate
Management Environment (ACME) protocol that allows an ACME server to
validate the Delay-Tolerant Networking (DTN) Node ID for an ACME
client. A DTN Node ID is an identifier used in the Bundle Protocol
(BP) to name a "singleton endpoint": an endpoint that is registered
on a single BP Node. The DTN Node ID is encoded both as a certificate
Subject Alternative Name (SAN) identity of type otherName with an
Other Name form of BundleEID and as an ACME Identifier type "bundleEID".
This document is a product of the Automated Certificate Management Environment
Working Group of the IETF.
