Abstract

The invention discloses a unidirectional isolation GAP. The unidirectional isolation GAP comprises a first isolation device, a second isolation device, and a data reviewing device. The first isolationdevice is suitable for being communicated with a first network, and is used to receive first data from the first network, and is used for the protocol stripping of the first data; and is used to convert original data into second data; and is suitable for the unidirectional communication with the data reviewing device, and is used to transmit the second data to the data reviewing device unidirectionally; the data reviewing data is suitable for the reviewing of the second data, and when the second data passes the reviewing, the second data can be transmitted to the second isolation device; thesecond isolation device is suitable for the communication with the data reviewing device, and is used to receive the second data from the data reviewing device; and is suitable for restoring the second data into the original data; and is suitable for the unidirectional communication with the second network, and is used for the protocol encapsulation of the original data to acquire the first data again, and then the first data is transmitted to the second network. The invention also discloses a data transmission method.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a one-way isolation gatekeeper and a data transmission method. Background technique [0002] With the rapid development of network communication technology and the increasingly abundant information carried, the Internet has become an important infrastructure of human society. At the same time, network virus invasions and hacker attacks also began to flood the Internet, causing serious social impact and immeasurable economic losses. [0003] Even the adoption of products and technical means such as firewalls cannot prevent the frequent occurrence of virus intrusion and hacker attacks. For this reason, a large number of key networks and core business application networks choose to adopt a closed network that is completely isolated from the Internet (or other untrusted networks) to ensure information and system security, and use gatekeeper or one-way gatekeeper technology ...
