摘要
PURPOSE: A remote security service method of a centralized unmanned control system using the Internet without changing a constructed control system is provided to offer a middleware-typed service method for offering a security service on diverse control systems without largely changing the current system. CONSTITUTION: A control message for a control terminal received from a central control server is transmitted to a security client(S100). Certification for the security client is performed to form an SSL(Secure Sockets Layer) security tunnel with the security client(S110). Data received from the security client is transmitted to a security server through a SSL security tunnel(S120). The security server encrypts/transmits the control instruction data to the security client(S130). The security client enables the central control server to receive the data needed for control by decrypting/transmitting the data transmitted through the SSL security tunnel to the central control server(S140). The security client decrypts/transmits the encrypted control instruction to the control terminal(S150).
