Test IKEv2.EN.R.1.2.6.8: D-H transform NONE when rekeying the IKE_SA Part A: (BASIC)
To verify an IKEv2 device properly handles D-H transform NONE when rekeying the IKE_SA.
* [RFC 4718] - Sections 5.12
* Network Topology Connect the devices according to the Common Topology. * Configuration In each part, configure the devices according to the Common Configuration. * Pre-Sequence and Cleanup Sequence IKEv2 on the NUT is disabled after each part.

Packet #3: CREATE_CHILD_SA request Packet #3 is same as Common Packet #11 except SA Transform proposed in each test.
Part A:
SA Transform of Tranform Type D-H is replaced by the following SA
Transfrom.
SA Transform Next Payload 0 (last) Reserved 0 Transform Length 8 Transform Type 4 (D-H) Reserved 0 Transform ID 0 (NONE)
Part A: (BASIC) 1. TN1 starts to negotiate with NUT by sending IKE_SA_INIT request. 2. Observe the messages transmitted on Link A. 3. After reception of IKE_SA_INIT response from the NUT, TN1 transmits an IKE_AUTH request to the NUT. 4. Observe the messages transmitted on Link A. 5. TN1 transmits a CREATE_CHILD_SA request including a SA payload. A proposal in the SA payload contains 1 (IKE) in the Protocol ID field, 8 in the SPI size field and the rekeyed IKE_SA Initiator's SPI value. The message proposes D-H transform NONE. 6. Observe the messages transmitted on Link A.
Part A Step 2: Judgment #1 The NUT transmits an IKE_SA_INIT response including "ENCR_3DES", "PRF_HMAC_SHA1", "AUTH_HMAC_SHA1_96" and "D-H group 2" as accepted algorithms.
Step 4: Judgment #2 The NUT transmits an IKE_AUTH response including "ENCR_3DES", "AUTH_HMAC_SHA1_96" and "No Extended Sequence Numbers" as accepted algorithms.
Step 6: Judgment #3 The NUT transmits a CREATE_CHILD_SA response including a Notify payload of type NO_PROPOSAL_CHOSEN.
* None.
