> Technical Summary
>   This document describes a new Constrained Join Protocol (CoJP) and the
>   associated framework required for a new device, called "pledge", to
>   securely join a 6TiSCH network by leveraging a central server, the JRC.
>   The framework requires that the pledge and the JRC share a symmetric key
>   before the join process starts (pre-shared key). How this key is
>   provisioned is out of scope of this document.
>   Through a single CoAP request-response exchange secured by OSCORE, the
>   pledge requests admission into the network and the JRC configures it
>   with link-layer keying material and other parameters.
>   Join Request and Join Response messages defined for this purpose are to
>   be used as a generic transport based on CoAP for AKE messages between
>   the pledge and the JRC, through a Join Proxy. This enables bidirectional
>   communication of the pledge and the JRC, triggered by the pledge.
>   What AKE transports within those messages is not very relevant,
>   be it PSK, RPK or cert-authenticated DH. Once AKE completes and a
>   shared secret is in place at the pledge and the JRC, the join exchange
>   from this draft can take place, secured with OSCORE keys derived from
>   the shared secret.
> Working Group Summary
>   There was a controversy on OSCORE that this draft uses. OSCORE is now
>   approved by IESG. The draft does not have a dependency on EDHOC.
>   The chairs launched a second shorted WGLC after IETF 103.
