           Constrained Join Proxy for Bootstrapping Protocols
               draft-ietf-anima-constrained-join-proxy-01

Abstract

   This document defines a protocol to securely assign a pledge to a
   domain, represented by a Registrar, using an intermediary node
   between pledge and Registrar.  This intermediary node is known as a
   "constrained Join Proxy".

   This document extends the work of
   [I-D.ietf-anima-bootstrapping-keyinfra] by replacing the Circuit-
   proxy by a stateless/stateful constrained (CoAP) Join Proxy.  It
   transports join traffic from the pledge to the Registrar without
   requiring per-client state.
