Algorithm Agility Procedure
for the Resource Public Key Infrastructure (RPKI)
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 over a timescale of several years.
Consequently, no emergency transition is specified. The transition
procedure defined in this document supports only a top-down migration
(parent migrates before children).

1. Introduction
The Resource Public Key Infrastructure (RPKI) must accommodate
transitions between the public keys used by Certification Authorities
(CAs). Transitions of this sort are usually termed "key rollover".
Planned key rollover will occur regularly throughout the life of the
RPKI, as each CA changes its public keys, in a non-coordinated
fashion. (By non-coordinated we mean that the time at which each CA
elects to change its keys is locally determined, not coordinated
across the RPKI.) Moreover, because a key change might be
