Resource Public Key Infrastructure (RPKI) Validation Reconsidered
Abstract
This document specifies an alternative to the certificate validation
procedure specified in RFC 6487 that reduces aspects of operational
fragility in the management of certificates in the Resource Public
Key Infrastructure (RPKI), while retaining essential security
features.
The procedure specified in RFC 6487 requires that Resource
Certificates are rejected entirely if they are found to overclaim any
resources not contained on the issuing certificate, whereas the
validation process defined here allows an issuing Certification
Authority (CA) to chose to communicate that such Resource
Certificates should be accepted for the intersection of their
resources and the issuing certificate.
It should be noted that the validation process defined here considers
validation under a single trust anchor (TA) only. In particular,
concerns regarding overclaims where multiple configured TAs claim
overlapping resources are considered out of scope for this document.
This choice is signaled by a set of alternative Object Identifiers
(OIDs) per "X.509 Extensions for IP Addresses and AS Identifiers"
(RFC 3779) and "Certificate Policy (CP) for the Resource Public Key
Infrastructure (RPKI)" (RFC 6484). It should be noted that in case
these OIDs are not used for any certificate under a trust anchor, the
validation procedure defined here has the same outcome as the
procedure defined in RFC 6487.
Furthermore, this document provides an alternative to Route Origin
Authorization (ROA) (RFC 6482) and BGPsec Router Certificate (BGPsec
PKI Profiles -- publication requested) validation.
