Abstract:
   TCP servers are visible on the Internet to unauthorized clients, as
   the existence of a TCP server is leaked in the TCP handshake before
   applications have a chance to authenticate the client.

   We present a small modification to the initial TCP handshake that
   allows TCP clients to replace the TCP ISN in the TCP SYN packet with
   an authorization token.  Based on this information, TCP servers may
   then chose to obscure their presence from unauthorized TCP clients.

   This RFC documents the specific method for calculating the
   authorization token to ensure interoperability and to minimize
   interference by middleboxes.  Mandating support for this method in
   operating system TCP/IP implementation will ensure that clients can
   connect to TCP servers protected by this method.
