How to Achieve Both "Physical Isolation" and "Secure File Transfer" under the State of Strong Supervision

Abstract

Communication security involves all aspects of the country and society, and financial security is of top priority. Through strong supervision and strong technical means, a "semaphore" file exchange station is established. The data transmission system is composed of a sending server, a receiving server, and a "semaphore" communication box. Physical connections between internal and external networks are eliminated to achieve the purpose of "physical isolation" and "secure file transfer".
