Abstract:
The CoAP and 6LoWPAN standards are fast emerging as key 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
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.
