Data sharing method and related device

Abstract

The embodiment of the invention provides a data sharing method and a related device, a first node initiates consensus of sharing information to nodes in a block chain after acquiring a data sharing demand sent by a second node, the nodes in the block chain comprise the second node, the data sharing demand comprises an industrial Internet identifier of shared data, shared information comprises an associated industrial Internet identifier of the first node, an industrial Internet identifier of the second node and an identifier of the shared data, and a ciphertext of the shared data is sent to the second node after consensus feedback of the block chain to the shared information is obtained. After receiving the ciphertext of the shared data sent by the first node, the second node decrypts theciphertext by using the key to obtain the shared data. The first node shares the data after the shared information is subjected to consensus, so that the record of data sharing can be traced back, andthe security of data sharing is improved. The data sent to the second node by the first node is the ciphertext after the shared data is encrypted, so that the security is further improved.

Description

technical field [0001] The present application relates to the field of data processing, and more specifically, to a data sharing method and a related device. Background technique [0002] In the industrial Internet system, when companies provide data to purchasing companies, in order to protect the privacy of data, the data is only open to purchasing companies and private to other companies. However, the behavior of purchasing companies cannot be traced back, and it is difficult to guarantee that purchasing companies will not arbitrarily share data. Provide or sell to other companies, resulting in data leakage and data abuse. It can be seen that in the industrial Internet system, the data circulation between enterprises has the problems of low security and poor privacy. Contents of the invention [0003] In view of this, the present application provides a data sharing method, device, device and readable storage medium for improving the security and privacy of shared data,...
