           Constrained Join Proxy for Bootstrapping Protocols
            draft-vanderstok-anima-constrained-join-proxy-02

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 [ietf-anima-bootstrapping-keyinfra]
   by replacing the Circuit-proxy by a stateless constrained Join Proxy,
   that transports routing information.
