Title

  Test IKEv2.EN.R.1.1.10.1: Sending Certificate Payload
  Part A: (ADVANCED)


Purpose


  To verify an IKEv2 device handles a CERTREQ payload and transmits a CERT payload
  propoerly.


References

  * [RFC 4306] - Sections 1.2 and 3.8


Test Setup

  * Network Topology
      Connect the devices according to the Common Topology.
  * Configuration
      In each part, configure the devices according to the following IKE peer configuration.
Authentication Method
Remote X.509 Certificate - Signature
  * Pre-Sequence and Cleanup Sequence
      IKEv2 on the NUT is disabled after each part.


Procedure

(End-node)           (End-Node)
    |                    |
    |<-------------------| IKE_SA_INIT request (HDR, SAi1, KEi, Ni)
    |                    | (Packet #1)
    |------------------->| IKE_SA_INIT Response (HDR, SAr1, KEr, Nr)
    |                    | (Judgement #1)
    |                    |
    |<-------------------| IKE_AUTH request (HDR, SK {IDi, CERTREQ, AUTH, N, SAi2, TSi, TSr})
    |                    | (Packet #2)
    |------------------->| IKE_AUTH response (HDR, SK {IDr, CERT, AUTH, N, SAr2, TSi, TSr})

  Part A: (ADVANCED)
     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 with a CERTREQ payload to the NUT.
     4. Observe the messages transmitted on Link A.


Observable Result


  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 with a CERT payload which contains 4 (X.509
       Certificate - Signature) as Certificate Encoding and the NUT's certificate as Certificate Data.


Possible Problems

  * None.
