=head1 TEST PROCEDURE
=begin html
This test check is following.
* PHASE I
Either IDENTITY PROTECTION EXCHANGE or AGGRESSIVE EXCHANGE is performed as a pre sequence.
IDENTITY PROTECTION EXCHANGE

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

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

(6) <======== HDR*; IDir; HASH_R
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).
AGGRESSIVE EXCHANGE

1. Recieve 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). There
can be only one Proposal and one Transform offered (i.e. no choices)
in order for the aggressive exchange to work. 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. Random information provided by both parties SHOULD
be used by the authentication mechanism to provide shared proof of
participation in the exchange. Additionally, the initiator transmits
identification information.
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.
Random information provided by both parties SHOULD be used by the
authentication mechanism to provide shared proof of participation in
the exchange. Additionally, the responder transmits identification
information. All of this information is transmitted under the
protection of the agreed upon authentication function. Local
security policy dictates the action of the responder if no proposed
protection suite is accepted. One possible action is the
transmission of a Notify payload as part of an Informational
Exchange.
3. Recieve the third message from NUT
In the third (3) message, the initiator transmits the results of the
agreed upon authentication function. This information is transmitted
under the protection of the common shared secret. Local security
policy dictates the action if an error occurs during these messages.
One possible action is the transmission of a Notify payload as part
of an Informational Exchange.
The test sequence is following.

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.

=head1 JUDGEMENT
In Phase I , messages must be exchanged correctly.
In Phase II , the first message's Transform Payload Format must be base
on description of RFC(see above Verification Points).

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.

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.
(omit)
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.
