INITIALIZATION

TEST PROCEDURE

  This test check is following.


           IDENTITY PROTECTION EXCHANGE


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


(2)                     <========       HDR; SA


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


(4)                     <========     HDR; KE; NONCE


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


(6)                     <========     HDR*; IDir; HASH_R <----ID protocol/port : TCP/300(invalid value)




   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). 


   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).  


 * PHASE II


                      QUICK MODE


 #   Initiator(NUT)     Direction      Responder(TN)
(1)  HDR*, HASH(1), 
           SA, Ni       ========> X                        <----must not start Phase II       
                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).
      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.

JUDGEMENT

      In Phase I the first to the fifth message must be exchanged correctly.
      The sixth message must not be accepted. And In Phase II
      the first message must not be returned(Not establish ISAKMP SA, 
      Not start negotiation of Phase II).

TERMINATION

  Clean up SAD and SPD

REFERENCE

  RFC2407
  4.6.2 Identification Payload Content


   The Identification Payload is used to identify the initiator of the
   Security Association.  The identity of the initiator SHOULD be used
   by the responder to determine the correct host system security policy
   requirement for the association.  For example, a host might choose to
   require authentication and integrity without confidentiality (AH)
   from a certain set of IP addresses and full authentication with
   confidentiality (ESP) from another range of IP addresses.  The
   Identification Payload provides information that can be used by the
   responder to make this decision.


   During Phase I negotiations, the ID port and protocol fields MUST be
   set to zero or to UDP port 500.  If an implementation receives any
   other values, this MUST be treated as an error and the security
   association setup MUST be aborted.  This event SHOULD be auditable.


   The following diagram illustrates the content of the Identification
   Payload.

  5.8 Identification Payload Processing


(omit)


   When an Identification payload is received, the receiving entity
   (initiator or responder) MUST do the following:


   1.  Determine if the Identification Type is supported.  This may be
       based on the DOI and Situation.  If the Identification
       determination fails, the message is discarded and the following
       actions are taken:


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


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