   1. Receive the first message from NUT
      In the first message (1), the initiator generates a proposal it
      considers adequate to protect traffic for the given situation.  The
      Security Association, Proposal, and Transform payloads are included
      in the Security Association payload (for notation purposes).
      Keying material used to arrive at a common shared secret and random 
      information which is used to guarantee liveness and protect against 
      replay attacks are also transmitted. Additionally, the initiator 
      transmits identification information.


   2. Send the second message from TN
      In the second message (2), the responder indicates the protection
      suite it has accepted with the Security Association, Proposal, and
      Transform payloads. 
      Keying material used to arrive at a common shared secret and random 
      information which is used to guarantee liveness and protect against
      replay attacks is also transmitted.Additionally, the responder 
      transmits identification information and the results of the agreed
      upon authentication function(hash function). 


   3. Receive the third message from NUT
      In the third (3) message, the initiator send the results of the 
      agreed upon authentication function(hash function)

  RFC2408
  4.2 Security Association Establishment


(omit)


   When responding to a Security Association payload, the responder MUST
   send a Security Association payload with the selected proposal, which
   may consist of multiple Proposal payloads and their associated
   Transform payloads.  Each of the Proposal payloads MUST contain a
   single Transform payload associated with the Protocol.  The responder
   SHOULD retain the Proposal # field in the Proposal payload and the
   Transform # field in each Transform payload of the selected Proposal.
   Retention of Proposal and Transform numbers should speed the
   initiator's protocol processing by negating the need to compare the
   respondor's selection with every offered option.  These values enable
   the initiator to perform the comparison directly and quickly.  The
   initiator MUST verify that the Security Association payload received
   from the responder matches one of the proposals sent initially.


  RFC2409
  5. Exchanges


(omit)


   During security association negotiation, initiators present offers
   for potential security associations to responders. Responders MUST
   NOT modify attributes of any offer, attribute encoding excepted (see
   Appendix A).  If the initiator of an exchange notices that attribute
   values have changed or attributes have been added or deleted from an
   offer made, that response MUST be rejected.
