    BRSKI enrollment of with disconnected Registrars -- smarkaklink
                 draft-richardson-anima-smarkaklink-02

Abstract

   This document details the mechanism used for initial enrollment using
   a smartphone of a BRSKI Registrar system.

   There are two key differences in assumption from
   [I-D.ietf-anima-bootstrapping-keyinfra]: that the intended registrar
   has Internet, and that the Pledge has no user-interface.

   This variation on BRSKI is intended to be used in the situation where
   the registrar device is new out of the box and is the intended
   gateway to the Internet (such as a home gateway), but has not yet
   been configured.  This work is also intended as a transition to the
   Wi-Fi Alliance work on the Device Provisioning Protocol (DPP).
