Verification Points
Process the Certificate Data field. If the Certificate Data is
invalid or improperly formatted, the payload is discarded and the
following actions are taken:
(a) The event, INVALID CERTIFICATE, MAY be logged in the
appropriate system audit file.
(b) An Informational Exchange with a Notification payload
containing the INVALID-CERTIFICATE message type MAY be sent
to the transmitting entity. This action is dictated by a
system security policy.
Configuration
Initiator and Responder generate the public key and the secret key
Certificate Payload Format(HOST-2:Initiator)
Certificate Data field : 0 (invalid value)

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).
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.
Additionally the responder send Certificate Request Payload.
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. The signed data, SIG_I is the result of the negotiated
digital signature algorithm applied to HASH_I.
Additionally the initiator send invalid Certificate and Certificate
Request Payload
6. Receive the sixth message from NUT
In the sixth message (6), the responder indicates either an ISAKMP
Notify Payload or an ISAKMP delete Payload.
The first and the fourth message must be exchanged correctly.
The fifth message must not be accepted.
And the sixth message(6-A) must not be returned
(* or INVALID-CERTIFICATE message(6-B) is returned).
*option : if you want to check the retruned Notify message.

RFC2408
5.9 Certificate Payload Processing
(omit)
When a Certificate payload is received, the receiving entity
(initiator or responder) MUST do the following:
1. Determine if the Certificate Encoding is supported. If the
Certificate Encoding is not supported, the payload is discarded
and the following actions are taken:
(a) The event, INVALID CERTIFICATE TYPE, MAY be logged in the
appropriate system audit file.
(b) An Informational Exchange with a Notification payload
containing the INVALID-CERT-ENCODING message type MAY be
sent to the transmitting entity. This action is dictated by
a system security policy.
2. Process the Certificate Data field. If the Certificate Data is
invalid or improperly formatted, the payload is discarded and the
following actions are taken:
(a) The event, INVALID CERTIFICATE, MAY be logged in the
appropriate system audit file.
(b) An Informational Exchange with a Notification payload
containing the INVALID-CERTIFICATE message type MAY be sent
to the transmitting entity. This action is dictated by a
# system security policy.
