    abstract =  {This document describes a method for using existing unidirectional authentication mechanisms such as RADIUS, SecurID, and OTP within IPSec's ISAKMP protocol. The purpose of this draft is not to replace or enhance the existing authentication mechanisms described in {[}IKE{]}, but rather to allow them to be extended using legacy authentication mechanisms.},
