Hi All

 A new version of the draft has been upload based on the review comments received so far.

 Main changes are
-explaining in more detail the issue with nonce reuse with multi-senders and
-how to deal with late joiners to the group.

Regards
Sandeep

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.

Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
