Abstract:
The CoAP standard is fast emerging as a key protocol in the area of
resource-constrained devices. Such IP-based systems are foreseen to
be used for building and lighting control systems where devices
interconnect with each other, forming, for example, 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 based on the DTLS which is already supported
for unicast communication for 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.
