1. Introduction
[I-D.ietf-ace-dtls-authorize] only specifies use of DTLS
[I-D.ietf-tls-dtls13] but works equally well for TLS. For many
constrained implementations, CoAP over UDP [RFC7252] is the first
choice, but when deploying ACE in networks controlled by other
entities (such as the Internet), UDP might be blocked on the path
between the client and the RS, and the client might have to fall back
to CoAP over TCP [RFC8323] for NAT or firewall traversal. This
feature is supported by the OSCORE profile
[I-D.ietf-ace-oscore-profile] but is lacking from the DTLS profile.
This document updates [I-D.ietf-ace-dtls-authorize] by specifying
that the profile applies to TLS as well as DTLS. The same access
rights are valid in case transport layer security is either DTLS or
TLS, and the same access token can be used.
2. IANA Considerations
No IANA Considerations.
3. Security Considerations
The security consideration and requirements in TLS 1.3 [RFC8446] and
BCP 195 [RFC7525] [RFC8996] also apply to this document.
