  1. Extensions to the Emergency Services Architecture for dealing with Unauthenticated and Unauthorized Devices H.  Schulzrinne,  S.  McCann,  G.  Bajko,     H.  Tschofenig,  D.  Kroeselberg

  2. Status • http://tools.ietf.org/html/draft-ietf-ecrit-unauthenticated-access-05 • Scope  of  the  draft: • No  Access  Authentication (NAA) • No  ASP  (NASP) • Zero­balance ASP  (ZBP)

  3. Deployment Challenge • Today’s  networks  suffer  from  many   limitations. • Traffic inception  (e.g.,  HTTP  redirect) • Lots  of  userinteraction  for  network  access • Claim: • Described  solution  cannot  be  deployed  with   today’s  network.

  4. Lack  of  network  access   authorization • The  NAA  case  only  focuses  on  the  lack  of   credentials  but  does  not  consider  the  case   where  credentials  are  available  but  network   access  authorization  fails  nevertheless.   • Lack  of  authorization  at  the  application  layer  is   covered.
