Verification Points

IKE implementations SHOULD support the following attribute values

Parameter Value

ISAKMP SA Attributes - 3DES in CBC mode
- SHA
- Authentication via pre-shared keys.
- MODP over group number two.

So, IKE implementations SHOULD support SHA.

Configuration

       Initiator and Responder IKE parameter

Pre-Sequence

       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 ========>
                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.

JUDGEMENT

     The first message Attributes(SHA:2) must be included.
     And must conform to above Configuration.

TERMINATION

  Clean up SAD and SPD

REFERENCE

  RFC2409 
  4.Introduction


  (omit)


     IKE implementations MUST support the following attribute values:


      - DES [DES] in CBC mode with a weak, and semi-weak, key check
      (weak and semi-weak keys are referenced in [Sch96] and listed in
      Appendix A). The key is derived according to Appendix B.


      - MD5 [MD5] and SHA [SHA].


      - Authentication via pre-shared keys.


      - MODP over default group number one (see below).
