Security SG: Scope issues



In November meeting, we had a straw poll related to scope issues on
SSOH (Security Signaling Optimization during Handover) problem.  The
result was:

  Support EAP: Yes(20)/No(0) 
  Support Non-EAP: Yes(10)/ No(7)
  Support inter-technology handover: Yes(21)/No(0)

We need more detailed discussion to make a decision.  Please state
your opinion (as detailed as possible) on the scope-related issues
listed below by next Security SG teleconference on December 18, 2007.
If those issues are resolved, we will be in a good position to come to
an agreement on PAR/5C in January!

Issue 1: Should we support non-EAP in addition to EAP?

Issue 2: Should we support handover to/from non-802 networks in
addition to handover within 802 networks?

Issue 3: Should we support inter-administrative-domain handover?

The definition of "administrative domain" is given below:

"
Administrative Domain

  A collection of End Systems, Intermediate Systems, and
  subnetworks operated by a single organization or administrative
  authority.  The components which make up the domain are assumed
  to interoperate with a significant degree of mutual trust among
  themselves, but interoperate with other Administrative Domains
  in a mutually suspicious manner.

  Administrative Domains can be organized into a loose hierarchy
  that reflects the availability and authoritativeness of
  authentication and authorization information.  This hierarchy does
  not imply administrative containment, nor does it imply a strict
  tree topology.
