Verification Points

IKE implementations MUST support the following attribute values

Parameter Value

ISAKMP SA Attributes - DES in CBC mode
- MD5
- Authentication via pre-shared keys.
- MODP over default group number one.

So, IKE implementations MUST support pre-shared keys.

Configuration

       Initiator and Responder IKE parameter
(It is shown that the mark of "*" permits anythings as attributes.)
At least, following parameter must be included in proposal.

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(PSK:1) 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.
