System and method for one-way security communication

The present invention relates to a one-way secure communication system and method. The system according to the invention, by constructing a message that includes data that is passed from the first network of the security region is transmitted through the first security server, and the dedicated line for transmitting the transmission message through a dedicated line from the first security server, receiving a message by recombinant and extracts the data of the first network from the received message, and a second security server that is transferred to the second network in the non-secure domain, said first security server sends the message using a one-way transmit-only protocol a transmission a dedicated line, and the second security server may receive a received message from a dedicated line using a one-way receive-only protocols.
