        Bootstrapping Remote Secure Key Infrastructures (BRSKI)
               draft-ietf-anima-bootstrapping-keyinfra-16

Abstract

   This document specifies automated bootstrapping of a remote secure
   key infrastructure (BRSKI) using manufacturer installed X.509
   certificate, 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 is complete when the cryptographic identity of the new
   key infrastructure is successfully deployed to the device but the
   established secure connection can be used to deploy a locally issued
   certificate to the device as well.
