  • Verification Points

           Determine if the Signature is supported.  If the Signature
       determination fails, the message is discarded and the following
       actions are taken:
    
       (a)  The event, INVALID SIGNATURE INFORMATION, MAY be logged in
            the appropriate system audit file.
    
       (b)  An Informational Exchange with a Notification payload
            containing the INVALID-SIGNATURE message type MAY be sent to
            the transmitting entity.  This action is dictated by a
            system security policy.

                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).


   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. The signed data, SIG_I is the result of the negotiated 
      digital signature algorithm applied to HASH_I.


   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. The signed data, SIG_R is the result of the negotiated 
      digital signature algorithm applied to HASH_R. 


   7. Receive the seventh message from NUT
      In the seventh message (7), the initiator indicates either an ISAKMP
      Notify Payload or an ISAKMP delete Payload.
=end html =head1 JUDGEMENT The first to the fifth message must be exchanged correctly. The sixth message must not be accepted. And the seventh message must not be returned (* or INVALID-SIGNATURE message is returned). (Not establish ISAKMP SA, Not start negotiation of Phase II). *option : if you want to check the retruned Notify message. =head1 TERMINATION Clean up SAD and SPD =head1 REFERENCE =begin html

  5.12 Signature Payload Processing


(omit)


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


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


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


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


   2.  Perform the Signature function as outlined in the DOI and/or Key
       Exchange protocol documents.  If the Signature function fails,
       the message is discarded and the following actions are taken:


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


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