Problems solved by technology

[0006] In practical applications, there will be scenarios where sensitive data is uploaded to the chain. Since sensitive data is stored in a distributed manner in the blockchain network, in order to ensure the security of sensitive data, related technologies adopt the scheme of uploading the summary of sensitive data to the chain instead of The scheme of directly uploading sensitive data to the chain leads to the fact that the blockchain network can only provide the client with the function of verifying sensitive data, but cannot directly provide reliable sensitive data, which causes a greater impact on the client's application based on sensitive data. Restrictions, because the client has to turn to other databases or file systems to obtain and verify sensitive data, and if the sensitive data is encrypted using symmetric or asymmetric encryption and uploaded to the chain, when the key is leaked safety cannot be guaranteed

Abstract

The invention provides a data processing method and device based on a block chain network, electronic equipment and a storage medium. The method comprises the following steps: receiving a transactionproposal submitted by a client and used for carrying out data query operation; executing endorsement verification on the transaction proposal, executing query operation on a state database in an account book of the node in the blockchain network to obtain corresponding key value pair data; calling a white box secret key library in the node through an original secret key carried by the transactionproposal to transform the original secret key to obtain a white box secret key, and decrypting the queried key value pair data through the white box secret key and a white box secret key algorithm; calling a transmission key library in the node so as to symmetrically encrypt the decrypted key value pair data through a transmission key and an encryption socket key algorithm; and constructing the symmetrically encrypted key value pair data into proposal response, and returning the proposal response to the client. According to the invention, the security of sensitive data uplink can be ensured, and the data security in data query is improved.

Description

[0001] Case Description [0002] This application is based on the Chinese patent application with the application number: 201910919440.X, the application date is September 26, 2019, and the invention name is: data processing method, device, electronic equipment and storage medium of blockchain network.
