Commercial National Security Algorithm (CNSA) Suite Profile for TLS and
                            DTLS 1.2 and 1.3
                 draft-cooley-cnsa-dtls-tls-profile-07

Abstract

   This document defines a base profile for TLS protocol versions 1.2
   and 1.3, as well as DTLS protocol versions 1.2 and 1.3 for use with
   the United States Commercial National Security Algorithm (CNSA)
   Suite.

   The profile applies to the capabilities, configuration, and operation
   of all components of US National Security Systems that use TLS or
   DTLS.  It is also appropriate for all other US Government systems
   that process high-value information.

   The profile is made publicly available here for use by developers and
   operators of these and any other system deployments.
