Requirements for Resource Public Key Infrastructure (RPKI) Relying
Parties
draft-ietf-sidrops-rp-06
Abstract
This document provides a single reference point for requirements for
Relying Party (RP) software for use in the Resource Public Key
Infrastructure (RPKI) in the context of securing Internet routing.
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 Relying Party (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.
