Product Description

One-way data transmission set, which has proprietary intellectual property rights and entirely fits the requirement of physical isolation, developed by Wuhan Engineering Science & Technology Institute and Wuhan Keyuan Anxin Co Ltd.Meanwhile it also have functions which segregate data safely and ensure one-way data transmission without feedback.
The machine adopts a design of dedicated hardware and modular work components with a combination of security functions such as security isolation, real-time information exchange and one-way transmission. It can be applied to equipment systems of various security classifications. Under the premise that physical isolation is safely realized in such equipment, the machine can transmit one-way no-feedback data from the devices of low security classification to those of high security classification in a high-speed, safe and stable way.
As a safe, efficient and flexible new-generation product for network isolation, the one-way data transmission machine subverts the ferry simulation technology of traditional gatekeeper products, and enables no-feedback channels of transmission at physical layer through the unique technology of one-way light transmission to ensure that data can only be introduced from the devices of low security classification and cannot come out of devices of high security classification. It completely cuts off the potential risk of cross-border transmission, truly achieves physical isolation, and reduces the disclosure risk to zero. Meanwhile, it significantly improves the speed and efficiency of data transfer. Now the machine has been awarded the "military C-level" certificate issued by "PLA Information Security Evaluation Center".
The one-way transmission can be widely applied in government agencies, military and public security organizations at all levels as well as the isolated environment of internal and external network with higher requirement of security to achieve secure exchange of information. One-way data transmission machine is especially applicable for the following scenarios.
1）Data transmission from none-classification network to classified network
2）Data transmission from network of low security classification (security domain) to network of high security classification (security domain).
 
Main Functions
1）Respectively connect the hosts of external net and encrypted storage devices of high security classification via USB interface, and establish a channel of data transmission.
2）Physically only one-way transmission channel exists at the transmitting and receiving ends during data transmission through one-way infrared electric devices to ensure the safety and reliability of data transmission.
3）Receive the data required to be shared by external networks via USB interface, then encode by the encoding system. The encoded data will be transmitted by the infrared modulating emission channel.
4）The decoding system encodes the data received by the infrared receiving channel, and the decoded data will be imported to the storage devices of high security classification.
5）Customized non-generic transport protocol is adopted to encode and decode data to isolate the threats at logic layer from devices of low security classification to those of high security classification.
6）Automatically check and correct errors in the transmission through redundant encoding.
