                 Algorithm Agility Procedure for RPKI.
                  draft-ietf-sidr-algorithm-agility-07

Abstract

   This document specifies the process that Certification Authorities
   (CAs) and Relying Parties (RPs) participating in the Resource Public
   Key Infrastructure (RPKI) will need to follow to transition to a new
   (and probably cryptographically stronger) algorithm set.  The process
   is expected to be completed in a time scale of months or years.
   Consequently, no emergency transition is specified.  The transition
   procedure defined in this document supports only a top-down migration
   (parent migrates before children).
