Verification Points

       Determine if the Key Exchange is supported.  If the Key Exchange
       determination fails, the message is discarded and the following
       actions are taken:

       (a)  The event, INVALID KEY INFORMATION, MAY be logged in the
            appropriate system audit file.

       (b)  An Informational Exchange with a Notification payload
            containing the INVALID-KEY-INFORMATION message type MAY be
            sent to the transmitting entity.  This action is dictated by
            a system security policy.

TEST PROCEDURE

  This test check is following.


                       AGGRESSIVE EXCHANGE


 #   Initiator(TN)         Direction      Responder(NUT)
(1)  HDR; SA, KE, Ni, IDii ========>                                     <-----Key Exchange Data field : 0(1byte)(invalid value)


(2-A)                    X <========       HDR; SA, KE, Nr, IDir, HASH_R <-----Must not transmit
                                       or
(2-B)                      <========       HDR; N/D
                        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).
      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. Receive the second message from NUT
      In the second message (2-B), the responder indicates either an ISAKMP
      Notify Payload or an ISAKMP delete Payload.

JUDGEMENT

      The first message must not be accepted. And the second message(2-A) 
      must not be returned (* or INVALID-KEY-INFORMATION message(2-B) is returned).
      *option : if you want to check the retruned Notify message.

TERMINATION

  Clean up SAD and SPD

REFERENCE

  RFC2408
  5.7 Key Exchange Payload Processing


(omit)


   When a Key Exchange payload is received, the receiving entity
   (initiator or responder) MUST do the following:


   1.  Determine if the Key Exchange is supported.  If the Key Exchange
       determination fails, the message is discarded and the following
       actions are taken:


       (a)  The event, INVALID KEY INFORMATION, MAY be logged in the
            appropriate system audit file.


       (b)  An Informational Exchange with a Notification payload
            containing the INVALID-KEY-INFORMATION message type MAY be
            sent to the transmitting entity.  This action is dictated by
            a system security policy.
