A cross-network isolation unidirectional import system based on a radio frequency technology and a data import method

Abstract

The invention discloses a cross-network isolation unidirectional import system based on a radio frequency technology and a data import method. The system comprises an extranet host, an Intranet host,a radio frequency card, a radio frequency tag reading equipment, a first light-emitting element, a first light-sensing device, a second light-emitting element and a second light-sensing device; the radio frequency card, the firt light emitting element and the first light-sensing device are connected with the external network host, the radio frequency tag reading device, the second light-emittingelement and the second light-sensing device are connected with the internal network host. The data importing method realizes one-way data importing based on the system. Cross-network data one-way import under the physical isolation condition is achieved, it is guaranteed that data in an internal network cannot flow to the external network while automatic, safe and reliable import of the external network data into the internal network is achieved, and the cross-network isolation data safe import problem of the external network and the internal network is thoroughly solved.

Description

technical field [0001] The invention relates to a cross-network isolation one-way import system and a data import method, in particular to a cross-network isolation one-way import system and a data import method based on radio frequency technology. Background technique [0002] At present, the government, military, military industry and other secret-related units, in accordance with the requirements of national security and confidentiality management, in order to prevent the occurrence of information and data leaks based on network connections, each unit has set up an internal dedicated network, and the business system and office environment are dedicated. It operates in the network, and according to the needs of actual business work, some units also establish multiple private networks with different security levels. However, the physical isolation of the network environment adds a lot of inconvenience to the necessary information and data transmission between different netw...

Problems solved by technology

[0006] Purpose of the invention: The technical problem to be solved by the present invention is to provide a cross-network isolation one-way import system and data import method based on radio frequency technology, which solves the defects that the current import system is not safe, reliable, and inefficient, and realizes physical isolation. The one-way import of cross-network data under certain conditions, while realizing the automatic, safe and reliable import of external network data to the internal network, ensures that the data in the internal network cannot flow to the external network, and completely solves the cross-network isolation between the external network and the internal network Data security import issues
