The Datagram Transport Layer Security (DTLS) Connection Identifier
draft-ietf-tls-dtls-connection-id-00
Abstract
This document specifies the "Connection ID" concept for the Datagram
Transport Layer Security (DTLS) protocol, version 1.2 and version
1.3.
A Connection ID is an identifier carried in the record layer header
that gives the recipient additional information for selecting the
appropriate security association. In "classical" DTLS, selecting a
security association of an incoming DTLS record is accomplished with
the help of the 5-tuple. If the source IP address and/or source port
changes during the lifetime of an ongoing DTLS session then the
receiver will be unable to locate the correct security context.
