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


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


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

  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).


   (omit)


  5. Exchanges


   There are two basic methods used to establish an authenticated key
   exchange: Main Mode and Aggressive Mode. Each generates authenticated
   keying material from an ephemeral Diffie-Hellman exchange. Main Mode
   MUST be implemented; Aggressive Mode SHOULD be implemented. In
   addition, Quick Mode MUST be implemented as a mechanism to generate
   fresh keying material and negotiate non-ISAKMP security services. In
   addition, New Group Mode SHOULD be implemented as a mechanism to
   define private groups for Diffie-Hellman exchanges. Implementations
   MUST NOT switch exchange types in the middle of an exchange.
