Data processing system and method and server

Abstract

The invention provides a data processing system and method and a server. The system comprises a data processing server, data acquisition equipment and optical shutter equipment, wherein the data processing server is used for generating a public key and a private key of a preset asymmetric encryption algorithm and sending the public key to the data acquisition equipment, and decrypting the encrypted acquisition data sent by the inner end of the optical shutter equipment through the private key; the data acquisition equipment is used for encrypting the acquired data through the public key to obtain encrypted acquired data and sending the encrypted acquired data to the outer end of the optical shutter equipment; and the optical shutter equipment is used for sending the encrypted acquired datareceived from the outer end to the data processing server from the inner end. According to the technical scheme, physical isolation is carried out through the optical shutter equipment, and the public key and the private key of the asymmetric encryption algorithm are adopted, and therefore, the risk that ciphertext data is decrypted can be effectively reduced, and the security of information transmission can be ensured.

Description

technical field [0001] The invention relates to the field of computers, in particular to a data processing system, method and server. Background technique [0002] With the increasingly developed information technology, especially 5G communication technology, Internet of Things devices have sprung up in the network. Some of these devices are terminals responsible for data collection, and send data compression and simple encryption back to the background data collection server for data analysis. and processing to obtain valuable data. [0003] When data is generated, transmitted to the data cache in the data acquisition server, any link in the entire chain may leak data, especially in some businesses with relatively high data confidentiality or confidential projects, the failure of any link may cause May cause irreparable damage. [0004] In the prior art, the foreground and the station are only separated by a firewall, and the data collection terminal and the background bu...

Problems solved by technology

[0005] In the above technical solution, the external network and the local area network are only separated by a firewall, and the physical link is still connected, and there are still security risks, so that the attacker can obtain the ciphertext data and the key, thereby causing the ciphertext data to be decrypted; the attacker It may even enter other devices on the LAN to steal or damage important data
