  • Verification Points

              
    • DH Group
      • 
        IKE implementations support a 2048 bit MODP group. 
        This group is assigned id 14.
        
    • PFS
      • 
        For PFS to exist the key used to protect transmission of data MUST
        NOT be used to derive any additional keys,
        and if the key used to protect transmission of data was derived 
        from some other keying material, that material MUST NOT be used to
        derive any more keys.
        
    • KE payload
      • 
        An optional Key Exchange payload can be exchanged to allow for 
        an additional Diffie-Hellman exchange and exponentiation per 
        Quick Mode. While use of the key exchange payload with Quick Mode is 
        optional it MUST be supported.

 * PHASE I


Either IDENTITY PROTECTION EXCHANGE or AGGRESSIVE EXCHANGE is performed as a pre sequence.

   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).


   2. Send the second message from TN
      In the second message (2), the responder indicates the protection
      suite it has accepted with the Security Association, Proposal, and
      Transform payloads. 


   3. Receive the third message from NUT
      In the third (3) message, the initiator send keying material 
      used to arrive at a common shared secret and random information 
      which is used to guarantee liveness and protect against replay attacks.


   4. Send the fourth message from TN
      In the fourth (4) message, the responder send keying material 
      used to arrive at a common shared secret and random information 
      which is used to guarantee liveness and protect against replay attacks.


   5. Receive the fifth message from NUT
      In the fifth (5) message, the initiator send identification 
      information and the results of the agreed upon authentication 
      function(hash function). 


   6. Send the sixth message from TN
      In the sixth (6) message, the responder send identification 
      information and the results of the agreed upon authentication 
      function(hash function).

                                                 SA established


   1. Recieve 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).  There
      can be only one Proposal and one Transform offered (i.e.  no choices)
      in order for the aggressive exchange to work.  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.  Random information provided by both parties SHOULD
      be used by the authentication mechanism to provide shared proof of
      participation in the exchange.  Additionally, the initiator transmits
      identification information.


   2. Send the second message from TN
      In the second message (2), the responder indicates the protection
      suite it has accepted with the Security Association, Proposal, and
      Transform payloads.  Keying material used to arrive at a common
      shared secret and random information which is used to guarantee
      liveness and protect against replay attacks is also transmitted.
      Random information provided by both parties SHOULD be used by the
      authentication mechanism to provide shared proof of participation in
      the exchange.  Additionally, the responder transmits identification
      information.  All of this information is transmitted under the
      protection of the agreed upon authentication function.  Local
      security policy dictates the action of the responder if no proposed
      protection suite is accepted.  One possible action is the
      transmission of a Notify payload as part of an Informational
      Exchange.


   3. Recieve the third message from NUT
      In the third (3) message, the initiator transmits the results of the
      agreed upon authentication function.  This information is transmitted
      under the protection of the common shared secret.  Local security
      policy dictates the action if an error occurs during these messages.
      One possible action is the transmission of a Notify payload as part
      of an Informational Exchange.



  The test sequence is following.

   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).
      And initiator send HASH(1) and Nonce. HASH(1) is the prf over the 
      message id (M-ID) from the ISAKMP header concatenated with the entire 
      message that follows the hash including all payload headers, 
      but excluding any padding added for encryption. Nonce is random 
      information which is used to guarantee liveness.KE is keying material 
      used to arrive at a common shared secret.

  RFC2409 
  3.3 Perfect Forward Secrecy


   When used in the memo Perfect Forward Secrecy (PFS) refers to the
   notion that compromise of a single key will permit access to only
   data protected by a single key. For PFS to exist the key used to
   protect transmission of data MUST NOT be used to derive any
   additional keys, and if the key used to protect transmission of data
   was derived from some other keying material, that material MUST NOT
   be used to derive any more keys.


   Perfect Forward Secrecy for both keys and identities is provided in
   this protocol. (Sections 5.5 and 8).

  5.5 Phase 2 - Quick Mode


  (omit)


   Quick Mode is essentially a SA negotiation and an exchange of nonces
   that provides replay protection. The nonces are used to generate
   fresh key material and prevent replay attacks from generating bogus
   security associations.  An optional Key Exchange payload can be
   exchanged to allow for an additional Diffie-Hellman exchange and
   exponentiation per Quick Mode. While use of the key exchange payload
   with Quick Mode is optional it MUST be supported.

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.
