Abstract:
CoAP and 6LoWPAN are fast emerging as the de-facto protocol standards
in the area of resource-constrained devices forming Low-power and
Lossy Networks (LLNs). Unicast communication in such networks are
secured at the transport layer using DTLS, as mandated by CoAP. For
various applications, IP multicast-based group communications in such
networks provide clear advantages. However, at this point, CoAP does
not specify how to secure group communications in an interoperable
way. This draft specifies two methods for securing CoAP-based group
communication at the transport layer and targets deployment scenarios
that may require group authentication, respectively source
authentication. The specification leverages the fact that DTLS is
already used as the mechanism of choice to secure unicast
communications and allows group communications security to be
implemented as an extension of DTLS record layer processing, thereby
minimizing incremental implementation cost.
