           Constrained Join Proxy for Bootstrapping Protocols
            draft-vanderstok-anima-constrained-join-proxy-04

Abstract

   This document defines a protocol to securely assign a pledge to an
   owner, using an intermediary node between pledge and owner.  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 constrained (CoAP) Join Proxy.  It transports
   join traffic from the pledge to the Registrar without requiring per-
   client state.
