INITIALIZATION

TEST PROCEDURE

  This test check is following.


                       AGGRESSIVE EXCHANGE


 #   Initiator(NUT)         Direction      Responder(TN)
(1)  HDR; SA, KE, Ni, IDii ========>

(2)                        <========       HDR; SA, KE, Nr, IDir, SIG_R
                                           CERT, CERT Req                <---Certificate Data field(CERT Req): The value which 
                                                                         is not available for Certificate Authority

     (HDR; N/D)     
                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).
      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.
      And the initiator send Certificate Request Payload.


   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.Additionally, the responder 
      transmits identification information and the signed data, SIG_I is 
      the result of the negotiated digital signature algorithm applied 
      to HASH_I.Additionally the responder send Certificate and Certificate
      Request Payload


   3. Receive the third message from NUT
      In the third message (3-B), the initiator indicates either an ISAKMP
      Notify Payload or an ISAKMP delete Payload.

JUDGEMENT

      The second message must not be accepted. And the third message(3-A) must not be returned
      (* or CERTIFICATE-UNAVAILABLE message(3-B) is returned).
      *option : if you want to check the retruned Notify message.

REFERENCE

  RFC2408
  5.10 Certificate Request Payload Processing


(omit)


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


   1.  Determine if the Certificate Encoding is supported.  If the
       Certificate Encoding is invalid, the payload is discarded and the
       following actions are taken:


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


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


       If the Certificate Encoding is not supported, the payload is
       discarded and the following actions are taken:


       (a)  The event, CERTIFICATE TYPE UNSUPPORTED, MAY be logged in
            the appropriate system audit file.


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


   2.  Determine if the Certificate Authority is supported for the
       specified Certificate Encoding.  If the Certificate Authority is
       invalid or improperly formatted, the payload is discarded and the
       following actions are taken:


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


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


   3.  Process the Certificate Request.  If a requested Certificate Type
       with the specified Certificate Authority is not available, then
       the payload is discarded and the following actions are taken:


       (a)  The event, CERTIFICATE-UNAVAILABLE, MAY be logged in the
            appropriate system audit file.


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