Abstract

The invention provides a network invasion preventing safe data transmission system and a network invasion preventing safe data transmission method. On condition that a network is physically isolated, data transmission between an internal-network computer and an external-network computer is realized through an RF communication module. In view of low safety in RF communication data transmission, identity authentication is performed between the internal-network computer and the external-network computer. Furthermore a data transmission manner with discontinuous RF communication intervals is used for frequently confirming the validity of the computer which transmits and receives data. Only under a precondition that the identity of the computer is valid, data transmission can be finished, thereby settling a problem of low safety in RF communication data transmission. Because high identity validity confirmation speed is realized in a two-dimensional code manner, speed and safety in data transmission are greatly improved. Data transmission speed in the network invasion preventing safe data transmission system and the network invasion preventing safe data transmission method is far higher than that of data transmission mode in which the two-dimensional code is utilized.

Description

technical field [0001] The invention relates to a data security transmission system and method for preventing network intrusion. Background technique [0002] The current conventional network communication technology can easily transmit data between two computers connected to the network. When a computer on the internal network is connected to the external network, external intruders can easily use operating system vulnerabilities to invade computers on the internal network. Physical isolation is required to achieve data transmission between the external network and the internal network. Someone in the industry proposed a two-dimensional code-based physical isolation transmission method (CN105049425A), in the case of physical isolation between the internal and external networks, data transmission is performed through the two-dimensional code. However, the two-dimensional code can only carry a limited amount of information, and the speed of data transmission cannot be accele...
