With the rapid development of informatization, various industries are accelerating their digitalization process. However, in the process of data transmission and archiving, the reliability of data is highly concerned. For some key industries such as government agencies, financial industry, military field, etc., data security is particularly emphasized. In order to avoid data leakage, black attacks, etc., multiple departments such as the Party, government, military, and enterprises have established dedicated internal networks.
However, with the continuous replacement of external network resources, the demand for data exchange between internal and external networks has increased. According to the Administrative Provisions on the Confidentiality of Computer Information System Networking, computer information systems involving state secrets must not be directly or indirectly connected to the Internet or other public information networks, and must be physically isolated. At the same time, the Guide to E-government Confidentiality Management jointly issued by the State Security Administration and the State Council Information Work Office also clearly pointed out that, according to the technical requirements for information confidentiality, classified networks cannot be directly connected to the Internet. If the Internet data is to be transmitted to the classified network, it must be transmitted from the Internet to the non classified network, and then from the non classified network to the classified network.
How to achieve secure transmission of data between internal and external networks in this context? The disc shuttle provided the answer.
What is a ferry machine? Ferry machines are generally dedicated machines for data exchange between internal and external networks, as well as between different levels of classified networks and individual classified machines, using certain security measures.
In practical applications, the intelligent disc shuttle system developed and produced by Dimensity Technology, which specializes in optical and magnetic storage, is widely used in various industries such as military, finance, and government agencies, providing an automated, secure, and reliable solution for exchanging data between internal and external networks. The system is based on mechatronics technology, using a robotic arm to simulate human manual operation (pure mechanical transmission), and a physical isolation method to automatically import external data (one-way) into the confidential network, avoiding uncontrollable factors caused by manual operation and effectively solving the problem of data exchange between external networks and confidential networks.

System Advantages
01 Unidirectional data transmission to prevent information leakage
The system automatically imports external data into the classified network through modular design and physical isolation, ensuring one-way data transmission, preventing information leakage, and achieving true physical isolation between the external network and the classified network. Meanwhile, MD5 verification technology is adopted to ensure the integrity of ferry data; Log auditing can view information such as ferry progress and start time to ensure data reliability.
02 Intelligent CD burning and convenient disc printing
The system adopts a fully automatic robotic arm for disc burning, disc data import, and unmanned operation; CD disc printing can print information such as file name, submitter, and disc shuttle time, making it easy to manage CDs. For example, simple instructions for importing data, file name, import date, importer, and other information can be printed on the CD disc, making it easier to manage the lifecycle of CDs in the future.
03 Seamless integration of on-demand development and design system
The Dimensity CD shuttle provides a secondary development interface that can be combined with the user's existing data exchange system. With professional modular design, it can be designed as needed to achieve functions such as data exchange approval, auditing, and logging.
Under the wave of domestic production, China's information and innovation industry is vigorously developing. The Dimensity intelligent disc shuttle system is independently developed and controllable, and the overall product design complies with the national "Regulations on the Management of Computer Information System Networking Confidentiality". It is an efficient and reliable data transmission platform that fully meets users' requirements for data security and reliability.
