Identifier-based Controllable Transmission Mechanism

In traditional networks, the initiation and establishment of the connection is not controlled, and the server provides services using well-known port numbers, which facilitates attackers to attack specific services. In this paper, we design, implement, and deploy an identifier-based controllable transmission mechanism (ICTM) that hides the server's real address and port, and authenticates, authorizes, and manages the initiator of the connection. We introduce the transmission control center (TCC) in the network transmission model. The server registers with the TCC for the network service provided by itself. Before the client establishes a connection, it must first obtain the connection authorization from the TCC. The sender carries the connection authorization information and establishes a connection to the server to obtain the service. By modifying the Linux kernel protocol stack, the ICTM can be used without any modification to existing application layer programs.
