  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).
=end html =head1 JUDGEMENT The first message's Proposal Payload Format must be base on description of RFC(see above Verification Points). =head1 TERMINATION Clean up SAD and SPD =head1 REFERENCE =begin html
  RFC2407
  2.4 Identifying Security Associations

(omit)
During phase 1 negotiations, the initiator and responder cookies determine the ISAKMP SA. Therefore, the SPI field in the Proposal payload is redundant and MAY be set to 0 or it MAY contain the transmitting entity's cookie.
(omit)
4.4.1.1 PROTO_ISAKMP
The PROTO_ISAKMP type specifies message protection required during Phase I of the ISAKMP protocol. The specific protection mechanism used for the IPSEC DOI is described in [IKE]. All implementations within the IPSEC DOI MUST support PROTO_ISAKMP.

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 "2" or "0". If there are additional Proposal payloads in the message, then this field will be 2. If the current Proposal payload is the last within the security association 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 entire Proposal payload, including generic payload header, the Proposal payload, and all Transform payloads associated with this proposal. In the event there are multiple proposals with the same proposal number (see section 4.2), the Payload Length field only applies to the current Proposal payload and not to all Proposal payloads.
o Proposal # (1 octet) - Identifies the Proposal number for the current payload. A description of the use of this field is found in section 4.2.
o Protocol-Id (1 octet) - Specifies the protocol identifier for the current negotiation. Examples might include IPSEC ESP, IPSEC AH, OSPF, TLS, etc.
o SPI Size (1 octet) - Length in octets of the SPI as defined by the Protocol-Id. In the case of ISAKMP, the Initiator and Responder cookie pair from the ISAKMP Header is the ISAKMP SPI, therefore, the SPI Size is irrelevant and MAY be from zero (0) to sixteen (16). If the SPI Size is non-zero, the content of the SPI field MUST be ignored. If the SPI Size is not a multiple of 4 octets it will have some impact on the SPI field and the alignment of all payloads in the message. The Domain of Interpretation (DOI) will dictate the SPI Size for other protocols.
o # of Transforms (1 octet) - Specifies the number of transforms for the Proposal. Each of these is contained in a Transform payload.
o SPI (variable) - The sending entity's SPI. In the event the SPI Size is not a multiple of 4 octets, there is no padding applied to the payload, however, it can be applied at the end of the message.
(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)
5.5 Proposal Payload Processing
When creating a Proposal Payload, the transmitting entity (initiator or responder) MUST do the following:
1. Determine the Protocol for this proposal.
2. Determine the number of proposals to be offered for this protocol and the number of transforms for each proposal. Transforms are described in section 3.6.
3. Generate a unique pseudo-random SPI.
4. Construct a Proposal payload.
