=end html =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
# Initiator(TN) Direction Responder(NUT) (1) HDR; SA ========>
(2) <======== HDR; SA
(3) HDR; KE; NONCE ========>
(4) <======== HDR; KE; NONCE
(5) HDR*; IDii; HASH_I ========>
(6) <======== HDR*; IDir; HASH_R
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.
3. Send the third message from TN 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. Receive the fourth message from NUT 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. Send the fifth message from TN In the fifth (5) message, the initiator send identification information and the results of the agreed upon authentication function(hash function).
6. Receive the sixth message from NUT In the sixth (6) message, the responder send identification information and the results of the agreed upon authentication function(hash function).

AGGRESSIVE EXCHANGE
# Initiator(TN) Direction Responder(NUT) NOTE (1) HDR; SA; KE; => Begin ISAKMP-SA or Proxy negotiation NONCE; IDii and Key Exchange
(2) <= HDR; SA; KE; NONCE; IDir; AUTH Initiator Identity Verified by Responder Key Generated Basic SA agreed upon
(3) HDR*; AUTH => Responder Identity Verified by Initiator SA established
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). 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. Recieve 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. 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. Send the third message from TN 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.
* PHASE II
QUICK MODE
# Initiator(TN) Direction Responder(NUT) (1) HDR*, HASH(1), SA, Ni,IDci, IDcr; ========>
(2) <======== HDR*, HASH(2), SA, Nr, IDci, IDcr; 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). 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. IDci and IDcr is identification information.
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. And responder send HASH(2) and Nonce. HASH(2) is identical to HASH(1) except the initiator's nonce-- Ni, minus the payload header-- is added after M-ID but before the complete message. Nonce is random information which is used to guarantee liveness. IDci and IDcr is identification information.
=end html =head1 JUDGEMENT In Phase I , messages must be exchanged correctly. In Phase II , the first message must be accepted. And the second message's Transform Payload Format must be base on description of RFC(see above Verification Points). =head1 TERMINATION Clean up SAD and SPD =head1 REFERENCE =begin html
  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.
(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.
