Abstract:
The Datagram Transport Layer Security protocol, DTLS, is usually
transported over UDP. In Constrained Node Networks, there may be
considerable limitations on the packet delivery rates and on
practically usable packet sizes. Applications often can control the
size and retransmission requirements of their data packets, but the
DTLS handshake is out of scope for such application optimizations.
This specification defines how to perform a DTLS handshake on top of
the CoAP protocol. The resulting DTLS connection may then be used
for instance for transporting CoAP, or as a source of keying
material. The latter case is particularly interesting if the CoAP
exchanges transporting the DTLS handshake messages traverse CoAP
proxies.
