                   BGPsec Router Certificate Rollover
                 draft-ietf-sidrops-bgpsec-rollover-01

Abstract

   Certificate Authorities (CAs) managing CA certificates and End-Entity
   (EE) certificates within the Resource Public Key Infrastructure
   (RPKI) will also manage BGPsec router certificates.  But the rollover
   of CA and EE certificates BGPsec router certificates have additional
   considerations for Normal and emergency rollover processes.  The
   rollover must be carefully managed in order to synchronize
   distribution of router public keys and BGPsec routers creating BGPsec
   Update messages verified with those router public keys.  This
   document provides general recommendations for the rollover process,
   as well as describing reasons why the rollover of BGPsec router
   certificates might be necessary.  When this rollover process is
   followed the rollover should be accomplished without routing
   information being lost.

2.  Introduction

   In BGPsec, a key rollover (or re-key) is the process of changing a
   router's key pair (or key pairs), issuing the corresponding new
   BGPsec router certificate and (if the old certificate is still valid)
   revoking the old certificate.  This process will need to happen at
