        Bootstrapping Remote Secure Key Infrastructures (BRSKI)
               draft-ietf-anima-bootstrapping-keyinfra-30

Abstract

   This document specifies automated bootstrapping of an Autonomic
   Control Plane.  To do this a Secure Key Infrastructure is
   bootstrapped.  This is done using manufacturer-installed X.509
   certificates, in combination with a manufacturer's authorizing
   service, both online and offline.  We call this process the
   Bootstrapping Remote Secure Key Infrastructure (BRSKI) protocol.
   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 deployment models with less
   stringent security requirements is included.  Bootstrapping 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.
