INITIALIZATION

TEST PROCEDURE

  This test check is following.


           IDENTITY PROTECTION EXCHANGE


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


(2)                  <========       HDR; SA
                Judgement (Check *1)


   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.

JUDGEMENT

        The first message must be accepted. 
        And the second message that has only one proposal(3DES:5,SHA:2,PSK:1,DH2:2) 
        and Transform # field = 2 must be returned.
        And must conform to above Configuration.

TERMINATION

  Clean up SAD and SPD

REFERENCE

  RFC2408
  4.1.1 Notation


   (omit)


     SA is an SA negotiation payload with one or more Proposal and
          Transform payloads. An initiator MAY provide multiple proposals
          for negotiation; a responder MUST reply with only one.

  4.2 Security Association Establishment


  (omit)


   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.


   When responding to a Security Association payload, the responder MUST
   send a Security Association payload with the selected proposal, which
   may consist of multiple Proposal payloads and their associated
   Transform payloads.  Each of the Proposal payloads MUST contain a
   single Transform payload associated with the Protocol.  The responder
   SHOULD retain the Proposal # field in the Proposal payload and the
   Transform # field in each Transform payload of the selected Proposal.
   Retention of Proposal and Transform numbers should speed the
   initiator's protocol processing by negating the need to compare the
   respondor's selection with every offered option.  These values enable
   the initiator to perform the comparison directly and quickly.  The
   initiator MUST verify that the Security Association payload received
   from the responder matches one of the proposals sent initially.




  RFC2409 
  3.2 Notation


   (omit)


   SA is an SA negotiation payload with one or more proposals. An
   initiator MAY provide multiple proposals for negotiation; a
   responder MUST reply with only one.


   (omit)


  7.1 Phase 1 using Main Mode


   The following diagram illustrates the payloads exchanged between the
   two parties in the first round trip exchange. The initiator MAY
   propose several proposals; the responder MUST reply with one.
