Embodiment approach

[0142] Among them, the purpose of the data node DS performing random decentralized processing on the data segments of the data to be processed is to obtain ciphertext fragments of the data segments, and these ciphertext fragments can represent the data segments, thereby realizing the encryption of the data segments. When the data node DS randomly disperses the data segments, a feasible implementation method is:

[0143] Assuming that the data segment contains private data X, two private data X are randomly generated for private data X 1 and x 2 , based on the private data X 1 and x 2 Divide private data X into {X 1 、X 1 ', X 2 、X 2 ', X a 、X a ', X b 、X b ′}; where X 2 =X-X 1 =X a , X 1 =X b , X 2 '=X-X 1 '=X b ',X 1 '=X a ’; data node DS sends the following ciphertext fragments to four computing nodes ES included in a group of computing nodes: {X 1 、X 1 '}, {X 2 、X 2 '}, {X a 、X a '}, {X b 、X b '}.

Abstract

The embodiment of the invention provides a data processing method, system and device, electronic equipment and a readable storage medium, and aims to improve the processing efficiency of data processing based on a multi-party security computing protocol. The data processing method is applied to a database engine, and comprises the steps of receiving a calculation task for to-be-processed data; determining position information of each data segment included in the to-be-processed data in the to-be-processed data according to a preset splitting rule; generating a first configuration file according to the calculation task and the position information; sending the first configuration file to a server so as to execute the calculation task in parallel for a plurality of data segments through the server to obtain a summary result of the to-be-processed data.
