        Bootstrapping Remote Secure Key Infrastructures (BRSKI)
               draft-ietf-anima-bootstrapping-keyinfra-26

Abstract

   This document specifies automated bootstrapping of an Autonomic
   Control Plane.  To do this a Remote Secure Key Infrastructure (BRSKI)
   is created using manufacturer installed X.509 certificates, in
   combination with a manufacturer's authorizing service, both online
   and offline.  Bootstrapping a new device can occur using a routable
   address and a cloud service, or using only link-local connectivity,
   or on limited/disconnected networks.  Support for lower security
   models, including devices with minimal identity, is described for
   legacy reasons but not encouraged.  Bootstrapping to is complete when
   the cryptographic identity of the new key infrastructure is
   successfully deployed to the device.  The established secure
   connection can be used to deploy a locally issued certificate to the
   device as well.
