        A Profile for Resource Certificate Repository Structure

Abstract

   This document defines a profile for the structure of the Resource
   Public Key Infrastructure (RPKI) distributed repository.  Each
   individual repository publication point is a directory that contains
   files that correspond to X.509/PKIX Resource Certificates,
   Certificate Revocation Lists and signed objects.  This profile
   defines the object (file) naming scheme, the contents of repository
   publication points (directories), and a suggested internal structure
   of a local repository cache that is intended to facilitate
   synchronization across a distributed collection of repository
   publication points and to facilitate certification path construction.

1.  Introduction

   To validate attestations made in the context of the Resource Public
   Key Infrastructure (RPKI) [RFC6480], relying parties (RPs) need
   access to all the X.509/PKIX Resource Certificates, Certificate
   Revocation Lists (CRLs), and signed objects that collectively define
   the RPKI.

   Each issuer of a certificate, CRL, or a signed object makes it
   available for download to RPs through the publication of the object
   in an RPKI repository.

   The repository system is a collection of all signed objects that MUST
   be globally accessible to all RPs.  When certificates, CRLs and
   signed objects are created, they are uploaded to a repository
   publication point, from whence they can be downloaded for use by RPs.

   This profile defines the recommended object (file) naming scheme, the
   recommended contents of repository publication points (directories),
   and a suggested internal structure of a local repository cache that
