Abstract:
The CoAP and 6LoWPAN standards are fast emerging as the de-facto
protocols in the area of resource-constrained devices. Such IP-based
systems are foreseen to be used for building and lighting control
systems where wireless devices interconnect with each other, forming
low-power and lossy networks (LLNs). Both multicast and its security
are key needs in these networks. This draft presents a method for
securing IPv6 multicast communication in LLNs based on the DTLS which
is already present for unicast in these CoAP devices. This draft
deals with the adaptation of the DTLS record layer to protect
multicast group communication, assuming that all group members
already have the group security association parameters in their
possession. The adapted DTLS record layer provides message
confidentiality, integrity and replay protection to group messages
using the group keying material before sending the message via IPv6
multicast to the group.
