        Bootstrapping Remote Secure Key Infrastructures (BRSKI)
               draft-ietf-anima-bootstrapping-keyinfra-06

Abstract

   This document specifies automated bootstrapping of a remote secure
   key infrastructure (BRSKI) using vendor installed X.509 certificate,
   in combination with a vendor's authorizing service, both online the
   Internet, 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.
