1. Introduction
This document defines a profile of DTLS 1.3 [I-D.ietf-tls-dtls13] and
TLS 1.3 [RFC8446] that offers communication security services for IoT
applications and is reasonably implementable on many constrained
devices. Profile thereby means that available configuration options
and protocol extensions are utilized to best support the IoT
environment.
For IoT profiles using TLS/DTLS 1.2 please consult [RFC7925]. This
document re-uses the communication pattern defined in [RFC7925] and
makes IoT-domain specific recommendations for version 1.3 (where
necessary).

TLS 1.3 has been re-designed and several previously defined
extensions are not applicable to the new version of TLS/DTLS anymore.
