    A DANE Record and DNSSEC Authentication Chain Extension for TLS
                draft-ietf-tls-dnssec-chain-extension-04

Abstract

   This draft describes a new TLS extension for transport of a DNS
   record set serialized with the DNSSEC signatures needed to
   authenticate that record set.  The intent of this proposal is to
   allow TLS clients to perform DANE authentication of a TLS server
   without needing to perform additional DNS record lookups.  It will
   typically not be used for general DNSSEC validation of TLS endpoint
   names.
