                Judgement (Check *1)


   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).


   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. 


   3. Receive the third message from NUT
      In the third (3) message, the initiator send keying material 
      used to arrive at a common shared secret and random information 
      which is used to guarantee liveness and protect against replay attacks.
=end html =head1 JUDGEMENT The first and the second message must be exchanged correctly.

And must conform to above Configuration. =head1 TERMINATION Clean up SAD and SPD =head1 REFERENCE =begin html

  5.3 Generic Payload Header Processing


   When creating any of the ISAKMP Payloads described in sections 3.4
   through 3.15 a Generic Payload Header is placed at the beginning of
   these payloads.  When creating the Generic Payload Header, the
   transmitting entity (initiator or responder) MUST do the following:


   1.  Place the value of the Next Payload in the Next Payload field.
       These values are described in section 3.1.


   2.  Place the value zero (0) in the RESERVED field.


   3.  Place the length (in octets) of the payload in the Payload Length
       field.


   4.  Construct the payloads as defined in the remainder of this
       section.


  (omit)


  5.7 Key Exchange Payload Processing


   When creating a Key Exchange Payload, the transmitting entity
   (initiator or responder) MUST do the following:


   1.  Determine the Key Exchange to be used as defined by the DOI.


   2.  Determine the usage of the Key Exchange Data field as defined by
       the DOI.


   3.  Construct a Key Exchange payload.


   4.  Transmit the message to the receiving entity as described in
       section 5.1.


  (omit)


  RFC2409 
  5. Exchanges


  (omit)


   The Diffie-Hellman public value passed in a KE payload, in either a
   phase 1 or phase 2 exchange, MUST be the length of the negotiated
   Diffie-Hellman group enforced, if necessary, by pre-pending the value
   with zeros.
