INITIALIZATION

TEST PROCEDURE

  This test check is following.


           IDENTITY PROTECTION EXCHANGE


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

JUDGEMENT

       The first message's Transform Payload Payload Format must be base 
       on description of RFC(see above Verification Points).

TERMINATION

  Clean up SAD and SPD

REFERENCE

  RFC2407
  4.4.2.1 KEY_IKE


   The KEY_IKE type specifies the hybrid ISAKMP/Oakley Diffie-Hellman
   key exchange (IKE) as defined in the [IKE] document.  All
   implementations within the IPSEC DOI MUST support KEY_IKE.



 
  RFC2408


  2.5.2 RESERVED Fields


   The existence of RESERVED fields within ISAKMP payloads are used
   strictly to preserve byte alignment.  All RESERVED fields in the
   ISAKMP protocol MUST be set to zero (0) when a packet is issued.  The
   receiver SHOULD check the RESERVED fields for a zero (0) value and
   discard the packet if other values are found.

  (omit)


    o  Next Payload (1 octet) - Identifier for the payload type of the
       next payload in the message.  This field MUST only contain the
       value "3" or "0".  If there are additional Transform payloads in
       the proposal, then this field will be 3.  If the current
       Transform payload is the last within the proposal, then this
       field will be 0.


    o  RESERVED (1 octet) - Unused, set to 0.


    o  Payload Length (2 octets) - Length in octets of the current
       payload, including the generic payload header, Transform values,
       and all SA Attributes.


    o  Transform # (1 octet) - Identifies the Transform number for the
       current payload.  If there is more than one transform proposed
       for a specific protocol within the Proposal payload, then each
       Transform payload has a unique Transform number.  A description
       of the use of this field is found in section 4.2.


    o  Transform-Id (1 octet) - Specifies the Transform identifier for
       the protocol within the current proposal.  These transforms are
       defined by the DOI and are dependent on the protocol being
       negotiated.


    o  RESERVED2 (2 octets) - Unused, set to 0.


    o  SA Attributes (variable length) - This field contains the
       security association attributes as defined for the transform
       given in the Transform-Id field.  The SA Attributes SHOULD be
       represented using the Data Attributes format described in section
       3.3.  If the SA Attributes are not aligned on 4-byte boundaries,
       then subsequent payloads will not be aligned and any padding will
       be added at the end of the message to make the message 4-octet
       aligned.

  5.3 Generic Payload Header Processing


   When creating any of the ISAKMP Payloads described in sections 3.4
   through 3.15 a Generic Payload Header is placed at the beginning of
   these payloads.  When creating the Generic Payload Header, the
   transmitting entity (initiator or responder) MUST do the following:


   1.  Place the value of the Next Payload in the Next Payload field.
       These values are described in section 3.1.


   2.  Place the value zero (0) in the RESERVED field.


   3.  Place the length (in octets) of the payload in the Payload Length
       field.


   4.  Construct the payloads as defined in the remainder of this
       section.


  (omit)


5.6 Transform Payload Processing


   When creating a Transform Payload, the transmitting entity (initiator
   or responder) MUST do the following:


   1.  Determine the Transform # for this transform.


   2.  Determine the number of transforms to be offered for this
       proposal.  Transforms are described in sections 3.6.


   3.  Construct a Transform payload.
