IETF 73 RMT WG Minutes
Monday, 17 November 2008
========================


1) Agenda Bashing
   The agenda was accepted without comment.

2) WG Progress

   The WG Chairs presented the following documents' status and
   there was discussion on each:

   a) The publication approval of "draft-ietf-rmt-bb-norm-revised" as 
      RFC 5401 was announced pending full author concurrence was 
      announced.  All authors have concurred except Mark Handley
      who had not yet responded.

   b) The "draft-ietf-rmt-bb-fec-rs" is approved but awaits the
      FEC Basic Schemes document due to dependency.
   
   c) A new version of "draft-ietf-rmt-bb-fec-basic-schemes-revised"
      was posted that should address the final IESG concerns.

   d) A new version of "draft-ietf-rmt-pi-norm-revised-07" was
      posted that is ready for AD/IESG review.

   e) The "draft-ietf-rmt-bb-lct-revised-07" is ready for 
      publication writeup.

   f) Both "draft-ietf-rmt-pi-alc-revised-06" and "draft-ietf-rmt-flute-
      revised-06" and are ready for working group last call.

   g) The following documents were updated and were discussed in
      separate presentations at this meeting:
       - "draft-ietf-rmt-simple-auth-for-alc-norm-00"
       - "draft-ietf-rmt-sec-discussion-03"
       - "draft-roca-rmt-newfcast-03"

3) FLUTE/ALC/LCT "EXT_FTI" Issue.
   Toni Palia had raised an issue questioning the consistency of
   the specification of the EXT_FTI header extension for
   the FLUTE/ALC/LCT documents.  Toni was not present but Mark
   Watson commented that, although the specification has been
   moved and is split among multiple documents as compared to
   earlier versions of the specification, the format is compatible
   with what was earlier specified. 

4) RMT Security Issues Document
   Brian Adamson presented a short summary of the updates to the
   "draft-ietf-rmt-sec-discussion-03".  This document may also be ready
   for working group last call, ready to fulfill its role as an
   informational reference for RMT Protocol Instantiation documents.

5) "TESLA for ALC/NORM"
   Vincent Roca provided a summary of the updated document, 
   "draft-ietf-msec-tesla-for-alc-norm-06".  Although this is
   an MSEC WG document, there is, of course, considerable 
   interest in the RMT WG regarding it.  The document had
   some comments and is close to ready for publication submission.

6) "Simple Authentication for ALC/NORM"
    Vincent Roca provided a summary of the updated document,
    "draft-ietf-rmt-simple-auth-for-alc-norm-00".  This was
    formerly a personal draft, but now has been adopted as
    an RMT WG document per prior RMT discussion.  One issue that
    was raised was concerning the description of use of Eliptical
    Curve Cryptography (ECC) which has some IPR claims 
    associated with it.  Brian Adamson volunteered to have the NRL
    team that developed an experimental "Secure NORM" solution
    that used ECC to review the implication of this.

7) "FCAST Discussion"
   Vincent Roca provided a summary of the updated document,
   "draft-roca-rmt-newfcast-03".  The principal questions were
   if there was sufficient interest to make this a working
   group document.  Gorry Fairhurst cited that he saw value
   in the document as an alternative to the FLUTE specification.
   Gorry had also raised the question of specifying a checksum
   for the Compound Object Header and/or object body (content). 
   The merits of header-only versus header+body.  Gorry suggested
   that a single approach be specified.  There was consensus that
   a checksum would be a useful addition to the header.  The
   question of accepting or rejecting this as a working group
   item was tabled pending more input from the mailing list
   and interested (or opposed) parties.

ACTION ITEMS:  The working group chairs will post working group last call requests for the ALC, FLUTE, and RMT Security Discussion documents.
