             A Profile for X.509 PKIX Resource Certificates

Abstract

   This document defines a standard profile for X.509 certificates for
   the purpose of supporting validation of assertions of "right-of-use"
   of Internet Number Resources (INRs).  The certificates issued under
   this profile are used to convey the issuer's authorization of the
   subject to be regarded as the current holder of a "right-of-use" of
   the INRs that are described in the certificate.  This document
   contains the normative specification of Certificate and Certificate
   Revocation List (CRL) syntax in the Resource Public Key
   Infrastructure (RPKI).  This document also specifies profiles for the
   format of certificate requests and specifies the Relying Party RPKI
   certificate path validation procedure.
