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.

In order to start the negotiation of IKE,
TN(HOST-1) transmits Echo Request to TN(HOST-2).
TEST PROCEDURE
This test check is following.
AGGRESSIVE EXCHANGE
# Initiator(NUT) Direction Responder(TN)
(1) HDR; SA, KE, Ni, IDii ========>
CERT Req
(2) <======== HDR; SA, KE, Nr, IDir, SIG_R
CERT, CERT Req <----Certificate Encoding field(CERT) : 0 (invalid)
(3-A)HDR[*]; SIG_I, CERT ========> X <-----Must not transmit
or
(3-B)HDR*; HASH(1); N/D ========>
(HDR; N/D)
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).
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.
And the initiator send Certificate Request Payload.
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.Additionally, the responder
transmits identification information and the signed data, SIG_I is
the result of the negotiated digital signature algorithm applied
to HASH_I.Additionally the responder send Certificate and Certificate
Request Payload
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.
JUDGEMENT
The second message must not be accepted. And the third message
must not be returned (* or INVALID-CERTIFICATE message is returned).
*option : if you want to check the retruned Notify message.

REFERENCE
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.
