                   An Out-of-Band Setup Protocol for
     Resource Public Key Infrastructure (RPKI) Production Services

Abstract

   This note describes a simple out-of-band protocol to ease setup of
   the Resource Public Key Infrastructure (RPKI) provisioning and
   publication protocols between two parties.  The protocol is encoded
   in a small number of XML messages, which can be passed back and forth
   by any mutually agreeable means which provides acceptable data
   integrity and authentication.

   This setup protocol is not part of the provisioning or publication
   protocol; rather, it is intended to simplify configuration of these
   protocols by setting up relationships and exchanging keying material
   used to authenticate those relationships.

RFC 8183                 RPKI Out-of-Band Setup                July 2017

1.  Introduction

   This note describes a small XML-based out-of-band protocol used to
   set up relationships between parents and children in the RPKI
   provisioning protocol [RFC6492] and between publishers and
   repositories in the RPKI publication protocol [RFC8181].

   The basic function of this protocol is public key exchange, in the
   form of self-signed X.509 certificates, but workshop experience has
   demonstrated that it's simpler for the user if we also bundle the
   other configuration information needed to bring up a new player into
