Abstract:
Wireless IP-based systems will be increasingly used for building
control systems in the future where wireless devices interconnect
with each other, forming low-power and lossy networks (LLNs). The
CoAP and 6LoWPAN standards are emerging as the de-facto protocols in
this area for resource-constrained devices. Both multicast and
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 available in CoAP devices. This draft deals
with the adaptation of the DTLS record layer to protect CoAP group
communication, assuming that all group member devices are already
configured with the group security association. The DTLS record
layer is used to provide authentication and encrypt multicast
messages using the group keying material before sending the message
via IPv6 multicast to the group.
