 Using DNS Security Extensions (DNSSEC) and DNS-based Authentication of
 Named Entities (DANE) as a Prooftype for XMPP Domain Name Associations
                 draft-miller-xmpp-dnssec-prooftype-04

Abstract

   This document defines a prooftype that uses DNS-based Authentication
   of Named Entities (DANE) for associating a domain name with an XML
   stream in the Extensible Messaging and Presence Protocol (XMPP).  It
   also defines a method that uses DNS Security (DNSSEC) for securely
   delegating a source domain to a derived domain in XMPP.

1.  Introduction

   The [XMPP-DNA] specification defines a framework for secure
   delegation and strong domain name associations (DNA) in the
   Extensible Messaging and Presence Protocol (XMPP).  This document
   defines a secure delegation method that uses DNS Security (DNSSEC)
   [RFC4033] in conjuction with the standard DNS SRV records [RFC2782]
   employed in domain name resolution in XMPP, with the result that a
   client or peer server that inititates an XMPP stream can legitimately
   treat a derived domain as a reference identifier during stream
   negotiation.  This document also defines a DNA prooftype that uses
   DNS-based Authentication of Named Entities [RFC6698] (DANE) to verify
   TLS certificates containing source domains or derived domains during
   stream negotiation.

2.  Terminology

   This document inherits XMPP terminology from [RFC6120], DNS
   terminology from [RFC1034], [RFC1035], [RFC2782] and [RFC4033], and
