Abstract:
CoAP has emerged as the de-facto IoT standard for communication
involving resource-constrained devices composing Low-power and Lossy
Networks (LLNs). CoAP mandates the adoption of the DTLS protocol to
secure unicast communication. However, in several IoT application
scenarios involving a group of multiple devices, the adoption of CoAP
multicast communication through IPv6 results in a number of
advantages, especially in terms of performance and scalability. Yet,
CoAP does not specify how to secure multicast group communication in
an interoperable way. This draft presents a method to secure
communication in a multicast group, through an adaptation of the DTLS
record layer. In particular, group members rely on the same group
keying material in order to secure both request messages sent via
multicast and possible unicast messages sent as response. Since the
group keying material is provided upon joining the group, all group
members are not required to perform any DTLS handshake with each
other. The proposed method makes it possible to provide either group
authentication or source authentication of secured messages.
