Test IKEv2.EN.I.1.1.6.5: Sending Multiple Transforms for CHILD_SA
Part A: Multiple Encryption Algorithms (ADVANCED)
To verify an IKEv2 device properly transmits IKE_AUTH request with multiple transforms
for CHILD_SA.
* [RFC 4306] - Sections 2.7 and 3.3
* Network Topology

Part A: Multiple Encryption Algorithms (ADVANCED)
1. NUT starts to negotiate with TN1 by sending IKE_SA_INIT request including a SA payload
as described above to the TN1.
2. Observe the messages transmitted on Link A.
3. NUT transmits an IKE_AUTH request including a SA payload as described above to the
TN1.
4. Observe the messages transmitted on Link A.
Part A
Step 2: Judgment #1
The NUT transmits an IKE_SA_INIT request including "ENCR_3DES",
"PRF_HMAC_SHA1", "AUTH_HMAC_SHA1_96" and "D-H group 2" as proposed
algorithms.
Step 4: Judgment #2
The NUT transmits an IKE_AUTH request including "ENCR_3DES", "ENCR_AES_CBC",
"AUTH_HMAC_SHA1_96" and "No Extended Sequence Numbers" as proposed algorithms.
* None.
