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 DH2.

Pre-Sequence

       In order to start the negotiation of IKE, 
       NUT 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(DH2:2) 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).


   In addition, IKE implementations SHOULD support: 3DES for encryption;
   Tiger ([TIGER]) for hash; the Digital Signature Standard, RSA [RSA]
   signatures and authentication with RSA public key encryption; and
   MODP group number 2.  IKE implementations MAY support any additional
   encryption algorithms defined in Appendix A and MAY support ECP and
   EC2N groups.


  (omit)


6.2 Second Oakley Group


   IKE implementations SHOULD support a MODP group with the following
   prime and generator. This group is assigned id 2 (two).


   The prime is 2^1024 - 2^960 - 1 + 2^64 * { [2^894 pi] + 129093 }.
   Its hexadecimal value is


         FFFFFFFF FFFFFFFF C90FDAA2 2168C234 C4C6628B 80DC1CD1
