  RPKI Multiple "All Resources" Trust Anchors Applicability Statement


   This document provides an applicability statement for the use of
   multiple, over-claiming 'all resources' (0/0) RPKI certificate
   authorities (CA) certificates used as trust anchors (TAs) operated by
   the Regional Internet Registry community to help mitigate the risk of
   massive downstream invalidation in the case of transient registry

2.  Introduction

   The RPKI is a hierarchical cryptologic system that uses X.509
   certificates to match and validate holdership of Internet number
   resources.  This validation follows the allocation change from IANA
   to an RIR, to an NIR or LIR, and ending with end users who make use
   of the address block.  Since these allocations can be
   cryptographically validated, this can then be tied to assertions made
   by the holder of those number resources.  As an improvement of this
   system, the RPKI was updated to add validation of origin routing
   announcements via ROAs.  These ROAs can then be independently and
   cryptographically validated by third parties to assure themselves
   that the origin of the announcement as seen in the actual routing
   system is valid.

   Since this system is envisioned to be used by network operators and
   ISPs to determine their routing decisions, there is a goal to be 100%
   correct 100% of the time.  This goal could be achieved if the system
   was contained in a static environment where there is little or no
   movement of holdership changes from one organization to another of
   number resources.  Unfortunately, this state cannot be achieved
   today, as movement of number resouces from from organization to
   organization is becoming common largely due to IPv4 scarcity.
