Dear all

We have submitted a new version of the multicast draft with improvements for the DICE BoF.
All comments and suggested improvements are welcome.

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.

Kind regards
Sandeep
