   Requirements for Resource Public Key Infrastructure (RPKI) Relying
                                Parties

Abstract

   This document provides a single reference point for requirements for
   Relying Party (RP) software for use in the Resource Public Key
   Infrastructure (RPKI).  It cites requirements that appear in several
   RPKI RFCs, making it easier for implementers to become aware of these
   requirements that are segmented with orthogonal functionalities.

1.  Introduction

   The RPKI RP software is used by network operators and others to
   acquire and verify Internet Number Resource (INR) data stored in the
   RPKI repository system.  RPKI data, when verified, allow an RP to
   verify assertions about which Autonomous Systems (ASes) are
   authorized to originate routes for IP address prefixes.  RPKI data
   also establishes binding between public keys and BGP routers, and
