System, method and device for data distributed encryption and decryption, electronic device and medium

Abstract

The invention provides a system, a method and a device for data distributed encryption and decryption, an electronic device and a medium. The system comprises: a master node, used for receiving an encryption and decryption request of specified data sent by a requester, dividing the specified data into segmented data according to a set segmented length, determining a segmented secret key of each segmented data, and sending the segmented data, the segmented secret keys and the segmented numbers to at least two slave nodes, and the segmented secret keys corresponding to the segmented data are different; and at least two slave nodes, used for encrypting and decrypting the segmented data according to the segmented key, and sending the encrypted and decrypted segmented data and the segmented number to the master node. The main node is also used for assembling the encrypted and decrypted segmented data into encrypted and decrypted data according to the segment number and returning the encrypted and decrypted data to the requester. According to the invention, the master node uniformly receives the encryption and decryption request and distributes the segmented data to the slave node for encryption and decryption, and the keys of the segmented data are different, so that the risk of key leakage is reduced, and the security of the data is improved.

Description

Technical field [0001] The present invention relates to the technical field of data encryption and decryption, in particular to a system, method, device, electronic equipment and medium for distributed encryption and decryption of data. Background technique [0002] In order to increase the speed of encryption and decryption, a distributed encryption and decryption method can be used for encryption and decryption of relatively large data. [0003] In the existing technical solutions, for distributed encryption and decryption of data, each distributed node shares the same encryption and decryption key. For different data encryption and decryption, the encryption and decryption keys are different each time. The key will be transmitted between distributed nodes. If the key is leaked when the key is transmitted between any two nodes, the data encryption and decryption will be completely cracked, and the risk of key leakage is high. Summary of the invention [0004] In view of the foreg...
