Example Embodiment

[0045] The present invention will be further described now in conjunction with accompanying drawing.

[0046] like figure 1 As shown, the present invention provides a fast data exchange system between networks, and specifically relates to a data exchange system between networks capable of real-time communication. The two processing units respectively perform data segmentation, encryption, combination and decryption, and realize communication with the outside, which can not only ensure the logical isolation between networks, but also realize high-speed network communication.

[0047] The system runs on a processor and is connected to multiple networks; the system includes: a first processing subsystem and a second processing subsystem;

[0048] The first processing subsystem is used to obtain real-time transmitted data from the external network communication system in the A network, and divide it into multiple data packets according to random rules, and use a private data pack...

Abstract

The invention belongs to the technical field of network data exchange, and particularly relates to a rapid data exchange system between networks, which comprises a first processing subsystem and a second processing subsystem, the first processing subsystem is used for acquiring data transmitted in real time from an external network communication system in one network, dividing the data into a plurality of data packets according to a random rule, encrypting the plurality of divided data packets one by one in sequence according to a private encryption algorithm, and sequentially sending the encrypted data packets to the second processing subsystem; the second processing subsystem is used for decrypting the plurality of encrypted data packets one by one in sequence according to a private decryption algorithm to obtain a plurality of decrypted data packets, and verifying each decrypted data packet; and combining the plurality of decrypted data packets after verification according to a sequence by using a random rule, verifying the combined data, and sending the combined data after verification to an external network communication system in another network.

Description

technical field [0001] The invention belongs to the technical field of network data exchange, and in particular relates to a fast data exchange system and exchange method between networks. Background technique [0002] At present, with the rapid development of information technology and the expansion of the application scope of 5G, big data, cloud computing and other technologies, a large number of Internet platforms such as the Internet of Things and the Industrial Internet have emerged. A trend of convergent development of various networks has been formed. However, due to the inconsistent construction time of various networks, a large number of information islands have been formed, and it is impossible to form the integration of data applications between different networks, to achieve fast data exchange, and to realize interconnection between networks. [0003] At present, in order to ensure the safe transmission of data, it is necessary to separate the transmitted data d...
