  This test check is following.


           the first IDENTITY PROTECTION EXCHANGE


 #   Initiator(TN)     Direction      Responder(NUT)
(1)  HDR; SA            ========>                        <---- Life Time = 60sec


(2)                     <========       HDR; SA          <---- Life Time = 60sec #1 : responder cookie


(3)  HDR; KE; NONCE     ========>

(5)  HDR*; IDii; HASH_I ========>


(6)                     <========     HDR*; IDir; HASH_R


   1. Send the first message from TN
      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. Receive the second message from NUT
      In the second message (2), the responder indicates the protection
      suite it has accepted with the Security Association, Proposal, and
      Transform payloads. 


   3. Send the third message from TN
      In the third (3) messages, 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.


   4. Receive the fourth message from NUT
      In the fourth (4) messages, the responder 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.


   5. Send the fifth message from TN
      In the fifth (5) messages, the initiator send identification 
      information and the results of the agreed upon authentication 
      function(hash function). 


   6. Receive the sixth message from NUT
      In the sixth (6) messages, the responder send identification 
      information and the results of the agreed upon authentication 
      function(hash function).  


 10sec after the first IDENTITY PROTECTION EXCHANGE, 
 negotiation of IKE(the second IDENTITY PROTECTION EXCHANGE) is started.


           The second IDENTITY PROTECTION EXCHANGE


 #   Initiator(TN)     Direction      Responder(NUT)
(1)  HDR; SA            ========>


(2)                     <========       HDR; SA        <---- #2 : responder cookie
                Judgement (Check *1)


   1. Send the first message from TN
      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).
      In this message, initiator cookie is different from the first IDENTITY 
      PROTECTION EXCHANGE's initiator cookie.


   2. Receive the second message from NUT
      In the second message (2), the responder indicates the protection
      suite it has accepted with the Security Association, Proposal, and
      Transform payloads.
=end html =head1 JUDGEMENT In the first IDENTITY PROTECTION EXCHANGE, the first to the sixth message must be exchanged correctly. In the second IDENTITY PROTECTION EXCHANGE, The first message must be accepted. And second message's responder cookie(#2) is not same as the first IDENTITY PROTECTION EXCHANGE's responder cookie(#1). =head1 TERMINATION Clean up SAD and SPD =head1 REFERENCE =begin html 
  RFC2408
  4.3 Security Association Modification


   Security Association modification within ISAKMP is accomplished by
   creating a new SA and initiating communications using that new SA.
   Deletion of the old SA can be done anytime after the new SA is
   established.  Deletion of the old SA is dependent on local security
   policy.  Modification of SAs by using a "Create New SA followed by
   Delete Old SA" method is done to avoid potential vulnerabilities in
   synchronizing modification of existing SA attributes.  The procedure
   for creating new SAs is outlined in section 4.2.  The procedure for
   deleting SAs is outlined in section 5.15.


   Modification of an ISAKMP SA (phase 1 negotiation) follows the same
   procedure as creation of an ISAKMP SA. There is no relationship
   between the two SAs and the initiator and responder cookie pairs
   SHOULD be different, as outlined in section 2.5.3.


   Modification of a Protocol SA (phase 2 negotiation) follows the same
   procedure as creation of a Protocol SA. The creation of a new SA is
   protected by the existing ISAKMP SA. There is no relationship between
   the two Protocol SAs.  A protocol implementation SHOULD begin using
   the newly created SA for outbound traffic and SHOULD continue to
   support incoming traffic on the old SA until it is deleted or until
   traffic is received under the protection of the newly created SA. As
   stated previously in this section, deletion of an old SA is then
   dependent on local security policy.
