                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.


   4. Send the fourth message from TN
      In the fourth (4) message, 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. Receive the fifth message from NUT
      In the fifth (5) message, the initiator send identification 
      information and the results of the agreed upon authentication 
      function(hash function).
=end html =head1 JUDGEMENT The first to the fourth message must be exchanged correctly. The fifth message must be encrypted and received. And must conform to above Configuration. =head1 TERMINATION Clean up SAD and SPD =head1 REFERENCE =begin html 
  RFC2408 
  3.1 ISAKMP Header Format


   (omit)


    o  Flags (1 octet) - indicates specific options that are set for the
       ISAKMP exchange.  The flags listed below are specified in the
       Flags field beginning with the least significant bit, i.e the
       Encryption bit is bit 0 of the Flags field, the Commit bit is bit
       1 of the Flags field, and the Authentication Only bit is bit 2 of
       the Flags field.  The remaining bits of the Flags field MUST be
       set to 0 prior to transmission.


      --  E(ncryption Bit) (1 bit) - If set (1), all payloads following
          the header are encrypted using the encryption algorithm
          identified in the ISAKMP SA. The ISAKMP SA Identifier is the
          combination of the initiator and responder cookie.  It is
          RECOMMENDED that encryption of communications be done as soon
          as possible between the peers.  For all ISAKMP exchanges
          described in section 4.1, the encryption SHOULD begin after
          both parties have exchanged Key Exchange payloads.  If the
          E(ncryption Bit) is not set (0), the payloads are not
          encrypted.


   (omit)


  RFC2409
  3.2 Notation


   (omit)


   Message encryption (when noted by a '*' after the ISAKMP header) MUST
   begin immediately after the ISAKMP header. When communication is
   protected, all payloads following the ISAKMP header MUST be
   encrypted.  Encryption keys are generated from SKEYID_e in a manner
   that is defined for each algorithm.
