  This test check is following.


 * PHASE I


Either IDENTITY PROTECTION EXCHANGE or AGGRESSIVE EXCHANGE is performed as a pre sequence.



           IDENTITY PROTECTION EXCHANGE

   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) 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. Receive the fourth message from NUT
      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. Send the fifth message from TN
      In the fifth (5) message, 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) message, the responder send identification 
      information and the results of the agreed upon authentication 
      function(hash function).



                        AGGRESSIVE EXCHANGE

                                                 SA established


   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).  There
      can be only one Proposal and one Transform offered (i.e.  no choices)
      in order for the aggressive exchange to work.  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.  Random information provided by both parties SHOULD
      be used by the authentication mechanism to provide shared proof of
      participation in the exchange.  Additionally, the initiator transmits
      identification information.


   2. Recieve 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.  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.
      Random information provided by both parties SHOULD be used by the
      authentication mechanism to provide shared proof of participation in
      the exchange.  Additionally, the responder transmits identification
      information.  All of this information is transmitted under the
      protection of the agreed upon authentication function.  Local
      security policy dictates the action of the responder if no proposed
      protection suite is accepted.  One possible action is the
      transmission of a Notify payload as part of an Informational
      Exchange.


   3. Send the third message from TN
      In the third (3) message, the initiator transmits the results of the
      agreed upon authentication function.  This information is transmitted
      under the protection of the common shared secret.  Local security
      policy dictates the action if an error occurs during these messages.
      One possible action is the transmission of a Notify payload as part
      of an Informational Exchange.



  The test sequence is following.

   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).
      And initiator send HASH(1) and Nonce. HASH(1) is the prf over the 
      message id (M-ID) from the ISAKMP header concatenated with the entire 
      message that follows the hash including all payload headers, 
      but excluding any padding added for encryption. Nonce is random 
      information which is used to guarantee liveness.


   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. And responder send HASH(2) and Nonce.
      HASH(2) is identical to HASH(1) except the initiator's nonce-- Ni,
      minus the payload header-- is added after M-ID but before the
      complete message. Nonce is random 
      information which is used to guarantee liveness.

   The Transform payload provides the initiating entity with the
   capability to present to the responding entity multiple mechanisms,
   or transforms, for a given protocol.  The Proposal payload identifies
   a Protocol for which services and mechanisms are being negotiated.
   The Transform payload allows the initiating entity to present several
   possible supported transforms for that proposed protocol.  There may
   be several transforms associated with a specific Proposal payload
   each identified in a separate Transform payload.  The multiple
   transforms MUST be presented with monotonically increasing numbers in
   the initiator's preference order.  The receiving entity MUST select a
   single transform for each protocol in a proposal or reject the entire
   proposal.  The use of the Transform number in multiple Transform
   payloads provides a second level OR operation, i.e.  Transform 1 OR
   Transform 2 OR Transform 3.  Example 1 below shows two possible
   transforms for ESP and a single transform for AH. Example 2 below
   shows one transform for AH AND one transform for ESP OR two
   transforms for ESP alone.  Note that the Next Payload field of the
   Transform payload points to another Transform payload or 0.  The
   Proposal payload delineates the different proposals.
