Title

  Test IKEv2.EN.I.1.1.10.1: Sending CERT Payload
  Part A: (ADVANCED)

Purpose

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

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

   NUT                  TN1

Packet #1

See below

Packet #1: IKE_SA_INIT response

IPv6 Header	Same as Common Packet #2
UDP Header	Same as Common Packet #2
IKEv2 Header	Same as Common Packet #2
SA Payload	Same as Common Packet #2
KE Payload	Same as Common Packet #2
Nr Payload	Next Payload	38 (CERTREQ)
	Other fields are same as the Common Packet #2
CERTREQ Payload	See below

CERTREQ Payload	Next Payload	0
	Critical	0
	Reserved	0
	Payload Length	Any
	Certificate Encoding	4 (X.509 Certificate - Signature)
	Certificate Authority	Any

  Part A: (ADVANCED)
     1. NUT starts to negotiate with TN1 by sending IKE_SA_INIT request.
     2. Observe the messages transmitted on Link A.
     3. After reception of IKE_SA_INIT request from the NUT, TN1 responds with an
         IKE_SA_INIT response with a CERTREQ payload to the NUT.
     4. Observe the messages transmitted on Link A.

Observable Results

  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 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
