Abstract:
   The BGPSEC protocol requires a method for protection from replay
   attacks, at least to control the window of exposure.  In the context
   of BGPSEC, a replay attack occurs when an adversary suppresses a
   prefix withdrawal (implicit or explicit) or replays a previously
   received BGPSEC announcement for a prefix that has since been
   withdrawn.  This informational document provides design discussion
   and comparison of multiple alternative replay-attack protection
   mechanisms weighing their pros and cons.  It is meant to be a
   companion document to the standards track I-D.-ietf-sidr-bgpsec-
   rollover that will specify a method to be used with BGPSEC for
   replay-attack protection.
