Hi All,

We have submitted a new version of the "DTLS-based Multicast Security" draft.   

http://tools.ietf.org/html/draft-keoh-dice-multicast-security-04

This version does not yet address the valuable comments from Michael StJohns.  We are still analyzing Michael's comments and will attempt to respond to them as soon as possible.

The changes in this version of the draft are as follows.

Changes from keoh-03 to keoh-04:
------------------------------------------
   o  Added description of Proxy operation in a DTLS-based multicast
      scenario in Section 4.5 (Proxy Operation).

   o  Corrected text in Section 2.2 (Security Requirements), item "h",
      to indicate that multicast source authentication is not specified
      in this version of the draft.

   o  Clarified that draft is written primarily for securing of CoAP
      based group communication, but that other protocols may also be
      supported if they have similar characteristics.  See Section 1
      (Introduction).

   o  Ran IETF spell checker and ID-Nits tools and corrected various
      issues throughout the document.

   o  Various editorial updates.

Best Regards,

Akbar

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.

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.
