                   Bootstrapping Key Infrastructures
               draft-ietf-anima-bootstrapping-keyinfra-01

Abstract

   This document specifies automated bootstrapping of an key
   infrastructure using vendor installed IEEE 802.1AR manufacturing
   installed certificates, in combination with a vendor based service on
   the Internet.  Before being authenticated, a new device has only
   link-local connectivity, and does not require a routable address.
   When a vendor provides an Internet based service, devices can be
   forced to join only specific domains but in limited/disconnected
   networks or legacy environments we describe a variety of options that
   allow bootstrapping to proceed.
