Abstract:
   This document describes the usage of the Datagram Transport Layer
   Security (DTLS) protocol to protect user messages sent over the
   Stream Control Transmission Protocol (SCTP).  It is an improved
   alternative to the existing RFC 6083.

   DTLS over SCTP provides mutual authentication, confidentiality,
   integrity protection, and replay protection for applications that use
   SCTP as their transport protocol and allows client/server
   applications to communicate in a way that is designed to give
   communications privacy and to prevent eavesdropping and detect
   tampering or message forgery.

   Applications using DTLS over SCTP can use almost all transport
   features provided by SCTP and its extensions.  This document is an
   improved alternative to RFC 6083 and removes the 16 kB limitation on
   protected user message size by defining a secure user message
   fragmentation so that multiple DTLS records can be used to protect a
   single user message.  It further contains a large number of security
   fixes and improvements.  It updates the DTLS versions and SCTP-AUTH
   HMAC algorithms to use.  It mitigates reflection attacks of data and
   control chunks and replay attacks of data chunks.  It simplifies
   secure implementation by some stricter requirements on the
   establishment procedures as well as rekeying to align with zero trust
   principles.
