Re: [Mip6] Consensus Call: Standardizing the auth protocol [I-D:draft-ietf-mip6-auth-protocol-00.txt]

Lacking any Security Directorate review opinion on this, I must regrettably
vote NO. I would, however, support pursuing the draft as an informational
RFC for 3GPP2 use only.

Subject: [Mip6] Consensus Call: Standardizing the auth protocol
[I-D:draft-ietf-mip6-auth-protocol-00.txt]

This is a consensus call to the WG on the issue of standardizing the
authentication-data-suboption mechanism for performing a binding between the
MN and HA. The issue has been discussed on the WG mailing list over
the last few weeks. The I-D
(draft-patil-mip6-whyauthdataoption-00.txt) has captured some of the
arguments, but there are several others that have been made on the
list as well. A summary of the discussion was sent out earlier and is
captured in :
http://www1.ietf.org/mail-archive/web/mip6/current/msg01690.html

The proposal here (in brief) is to standardize a mechanism specified
in I-D draft-ietf-mip6-auth-protocol-00.txt for performing MIP6
registration with a home agent. RFC3775 specifies the use of IPsec to
secure the binding update/ACK messages between the MN and HA. The
auth-protocol mechanism relies on the use of an
authentication-data-suboption and does not require the MN-HA to
establish an IPsec SA.
(For the discussion that has ensued so far, please refer to the MIP6
ML archives)

The question to the WG is:

1. Should we standardize the authentication protocol specified in I-D
   draft-ietf-mip6-auth-protocol-00.txt as an alternative (to the
   IPSec mechanism specified in RFC3775/6) means to securing the BUs
   and BAcks between the MN and HA. Note that this solution is an
   additional mechanism for doing registration with an HA and does not
   deprecate the currently specified solution.

   Yes      [ ]
   No      [ ]

The consensus call will close on October 12th, 2004.
