  • Verification Points

              
    • All offers made during a Quick Mode are logically related and 
must be consistant. For example, if a KE payload is sent, 
the attribute describing the Diffie-Hellman group (see section 
6.1 and [Pip97]) MUST be included in every transform of every 
proposal of every SA being negotiated.

      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). 


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

   1. Recieve 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).  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. 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.  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. Recieve the third message from NUT
      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. Receive the first message from NUT
      In the first message (1), the initiator generates a proposal it

      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

   All offers made during a Quick Mode are logically related and must be
   consistant. For example, if a KE payload is sent, the attribute
   describing the Diffie-Hellman group (see section 6.1 and [Pip97])
   MUST be included in every transform of every proposal of every SA
   being negotiated. Similarly, if client identities are used, they MUST
   apply to every SA in the negotiation.
