=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(NUT) Direction Responder(TN) (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. 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
# Initiator(NUT) Direction Responder(TN) 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. 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.
* PHASE II
QUICK MODE
# Initiator(NUT) Direction Responder(TN) (1) HDR*, HASH(1), SA, Ni ========>
(2) <======== HDR*, HASH(2), SA, Nr <-----Protocol-ID field : 248(invalid)
(3-A)HDR*, HASH(3) ========> X <-----Must not transmit or (3-B)HDR*, HASH(1), N/D ========> Judgement
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.
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. 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.
3. Receive the third message from NUT In the third message (3-B), the initiator indicates either an ISAKMP Notify Payload or an ISAKMP delete Payload.
=end html =head1 JUDGEMENT In Phase I , messages must be exchanged correctly. In Phase II , the second message must not be accepted. And the third message(3-A) must not be returned (* or INVALID-PROTOCOL-ID message(3-B) is returned). *option : if you want to check the retruned Notify message. =head1 TERMINATION Clean up SAD and SPD =head1 REFERENCE =begin html

  5.5 Proposal Payload Processing

(omit)
When a Proposal payload is received, the receiving entity (initiator or responder) MUST do the following:
1. Determine if the Protocol is supported. If the Protocol-ID field is invalid, the payload is discarded and the following actions are taken:
(a) The event, INVALID PROTOCOL, MAY be logged in the appropriate system audit file.
(b) An Informational Exchange with a Notification payload containing the INVALID-PROTOCOL-ID message type MAY be sent to the transmitting entity. This action is dictated by a system security policy.
2. Determine if the SPI is valid. If the SPI is invalid, the payload is discarded and the following actions are taken:
(a) The event, INVALID SPI, MAY be logged in the appropriate system audit file.
(b) An Informational Exchange with a Notification payload containing the INVALID-SPI message type MAY be sent to the transmitting entity. This action is dictated by a system security policy.
3. Ensure the Proposals are presented according to the details given in section 3.5 and 4.2. If the proposals are not formed correctly, the following actions are taken:
(a) Possible events, BAD PROPOSAL SYNTAX, INVALID PROPOSAL, are logged in the appropriate system audit file.
(b) An Informational Exchange with a Notification payload containing the BAD-PROPOSAL-SYNTAX or PAYLOAD-MALFORMED message type MAY be sent to the transmitting entity. This action is dictated by a system security policy.
4. Process the Proposal and Transform payloads as defined by the Next Payload field. Examples of processing these payloads are given in section 4.2.1.
