Data processing method and device and computer readable storage medium

Abstract

The invention discloses a data processing method and device and a computer readable storage medium. The method comprises the steps of a gateway node acquiring an encrypted communication request sent by a first node; wherein the first node is a node associated with the target terminal in the blockchain network; obtaining to-be-verified certificate information associated with a target user corresponding to the target terminal according to the encrypted communication request; when the to-be-verified certificate information has legality, obtaining identity identification information associated with the target user from the to-be-verified certificate information, and performing identity authentication on the target user based on the identity identification information; and when the identity authentication state is a successful state and a handshake task associated with the encrypted communication request is completed, establishing a session with the first node, and returning encrypted datainformation associated with the identity identification information to the first node according to an encryption key corresponding to the session. By adopting the method and the device, the privacy ofdata pulling can be enhanced, and the security of data transmission can be improved.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a data processing method, device, and computer-readable storage medium. Background technique [0002] In the existing technology, the lightweight node (i.e. the first node) corresponding to each entity object (such as an enterprise) can directly pull the entire node containing the respective business data from the full amount of nodes in the consensus network through the hash value. blocks. Since a block can contain the business data information of multiple enterprises (for example, enterprise A, enterprise B, ..., enterprise C), when the lightweight node of enterprise A is pulled to a certain block , while obtaining the business data associated with the enterprise A, the business data associated with other enterprises can also be obtained together, so that it is difficult to ensure the privacy of the business data of other enterprises in the same block. ...

AI Technical Summary

Problems solved by technology

Since a block can contain the business data information of multiple enterprises (for example, enterprise A, enterprise B, ..., enterprise C), when the lightweight node of enterprise A is pulled to a certain block , while obtaining the business data associated with the enterprise A, you can also obtain the business data associated with other enterprises, so that it is difficult to ensure the privacy of the business data of other enterprises in the same block

[0003] In addition, in the process of returning the above block to the light node corresponding to the enterprise A by the full node, the light node can directly get all the business data information from the acquired block, so that the light node is When an illegal node attacks, all the business data information in the process of business data transmission can be obtained, and it is difficult to ensure the transmission security of the business data information of these enterprises
