Verification Points
Process the remaining payloads (i.e. Proposal, Transform) of the
Security Association Payload. If the Security Association
Proposal (as described in sections 5.5 and 5.6) is not accepted,
then the following actions are taken:
(a) The event, INVALID PROPOSAL, MAY be logged in the
appropriate system audit file.
(b) An Informational Exchange with a Notification payload
containing the NO-PROPOSAL-CHOSEN message type MAY be sent
to the transmitting entity. This action is dictated by a
system security policy.

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).
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. Additionally, the initiator
transmits identification information.
2. Receive the second message from NUT
In the second message (2-B), the responder indicates either an ISAKMP
Notify Payload or an ISAKMP delete Payload.
The first message must not be accepted. And the second message(2-A) must not be returned
(* or NO-PROPOSAL-CHOSEN message(2-B) is returned).
*option : if you want to check the retruned Notify message.

5.4 Security Association Payload Processing
(omit)
When a Security Association payload is received, the receiving entity
(initiator or responder) MUST do the following:
1. Determine if the Domain of Interpretation (DOI) is supported. If
the DOI determination fails, the message is discarded and the
following actions are taken:
(a) The event, INVALID DOI, MAY be logged in the appropriate
system audit file.
(b) An Informational Exchange with a Notification payload
containing the DOI-NOT-SUPPORTED message type MAY be sent to
the transmitting entity. This action is dictated by a
system security policy.
2. Determine if the given situation can be protected. If the
Situation determination fails, the message is discarded and the
following actions are taken:
(a) The event, INVALID SITUATION, MAY be logged in the
appropriate system audit file.
(b) An Informational Exchange with a Notification payload
containing the SITUATION-NOT-SUPPORTED message type MAY be
sent to the transmitting entity. This action is dictated by
a system security policy.
3. Process the remaining payloads (i.e. Proposal, Transform) of the
Security Association Payload. If the Security Association
Proposal (as described in sections 5.5 and 5.6) is not accepted,
then the following actions are taken:
(a) The event, INVALID PROPOSAL, MAY be logged in the
appropriate system audit file.
(b) An Informational Exchange with a Notification payload
containing the NO-PROPOSAL-CHOSEN message type MAY be sent
to the transmitting entity. This action is dictated by a
system security policy.
