   The Resource Public Key Infrastructure (RPKI) Ghostbusters Record

Abstract

   In the Resource Public Key Infrastructure (RPKI), resource
   certificates completely obscure names or any other information that
   might be useful for contacting responsible parties to deal with
   issues of certificate expiration, maintenance, roll-overs,
   compromises, etc.  This document describes the RPKI Ghostbusters
   Record containing human contact information that may be verified
   (indirectly) by a Certification Authority (CA) certificate.  The data
   in the record are those of a severely profiled vCard.

1.  Introduction

   In the operational use of the RPKI, it can become necessary to
   contact, human to human, the party responsible for a resource-holding
   CA certificate, AKA the certificate's maintainer, be it the holder of
   the certificate's private key or an administrative person in the
   organization, a NOC, etc.  An important example is when the operator
   of a prefix described by a Route Origin Authorization (ROA) sees a
   problem, or an impending problem, with a certificate or Certificate
   Revocation List (CRL) in the path between the ROA and a trust anchor.
   For example, a certificate along that path has expired, is soon to
   expire, or a CRL associated with a CA along the path is stale, thus
   placing the quality of the routing of the address space described by
   the ROA in jeopardy.

   As the names in RPKI certificates are not meaningful to humans, see
   [RFC6484], there is no way to use a certificate itself to lead to the
   worrisome certificate's or CRL's maintainer.  So, "Who you gonna
   call?"

   This document specifies the RPKI Ghostbusters Record, an object
   verified via an end-entity (EE) certificate, issued under a CA
   certificate, the maintainer of which may be contacted using the
   payload information in the Ghostbusters Record.

   The Ghostbusters Record conforms to the syntax defined in [RFC6488].
   The payload of this signed object is a severely profiled vCard.
