Authentication and (D)TLS Profile for DNS-over-TLS and DNS-over-DTLS
draft-ietf-dprive-dtls-and-tls-profiles-00
Abstract
This document describes how a DNS client can use a domain name to
authenticate a DNS server that uses Transport Layer Security (TLS)
and Datagram TLS (DTLS). Additionally, it defines (D)TLS profiles
for DNS clients and servers implementing DNS-over-TLS and DNS-over-
DTLS.
