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/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 multicast communication in LLNs based on the DTLS which is
already present in CoAP devices. This draft deals with the
adaptation of the DTLS record layer to protect multicast group
communication, assuming that all member devices already have a group
key in their own possession. The DTLS record layer implementation is
used to encrypt a multicast message and to provide message
authentication using the group key before sending the message via IP
multicast to the group.
