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.
