Verification Points

IKE implementations SHOULD support the following attribute values

Parameter Value

ISAKMP SA Attributes - AES-128 in CBC mode
- MD5
- Authentication via pre-shared keys.
- MODP over default group number one.

So, IKE implementations SHOULD support AES.

Configuration

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(AES-CBC:7) must be included.
     And must conform to above Configuration.

TERMINATION

  Clean up SAD and SPD

Algorithms for Internet Key Exchange version 1 (IKEv1)
draft-hoffman-ikev1-algorithms-02.txt
3.  New algorithm requirements


   The new requirements for IKEv1 are:


   o  TripleDES for encryption MUST be supported
   o  AES-128 in CBC mode [RFC3602] SHOULD be supported
   o  SHA-1 for hashing and HMAC functions MUST be supported
   o  Pre-shared secrets for authentication MUST be supported
   o  AES-128 in CBC mode for HMAC functions ([RFC3566] and [RFC3664])
      SHOULD be supported
   o  Diffie-Hellman MODP group 2 (discrete log 1024 bits) MUST be
      supported
   o  Diffie-Hellman MODP group 14 (discrete log 2048 bits) [RFC3526]
      SHOULD be supported
   o  RSA for authentication with signatures SHOULD be supported


   The other algorithms that were listed at MUST-level and SHOULD-level
   in RFC 2409 are now MAY-level.  This includes DES for encryption, MD5
   and Tiger for hashing, Diffie-Hellman MODP group 1, Diffie-Hellman
   MODP groups with elliptic curves, DSA for authentication with
   signatures, and RSA for authentication with encryption.  DES for
   encryption, MD5 for hashing, Diffie-Hellman MODP group 1 are dropped
   to MAY due to cryptographic weakness.  Tiger for hashing,
   Diffie-Hellman MODP groups with elliptic curves, DSA for
   authentication with signatures, and RSA for authentication with
   encryption are dropped due to lack of any significant deployment and
   interoperability.
