   Title:   Secure BFD Sequence Numbers

   This document describes a new BFD Authentication mechanism,
   Meticulous Keyed ISAAC.  This mechanism can be used to authenticate
   BFD packets with less CPU time cost than using MD5 or SHA1, with the
   tradeoff of decreased security.  This mechanism cannot be used to
   signal state changes, but it can be used as an authenticated signal
   to maintain a session in the the "Up" state.  This document updates
   RFC 5880.
