Problems solved by technology

If in the process of multi-party security calculation, it is necessary to operate on string type data, such as string comparison and other operations, it is necessary to add additional algorithms to realize string type data operations, and the length and encoding of strings need to be considered and other problems, resulting in a more cumbersome algorithm, which in turn affects the efficiency and versatility of string type data operations

Abstract

Embodiments of the present invention provide a data processing method, device, and device for data processing. The method includes: obtaining a character string to be processed; converting the character string to be processed into target data of integer type according to the character encoding of each character in the character string to be processed; encrypting the target data , to obtain ciphertext data; input the ciphertext data into the multi-party secure computing system, perform preset operations on the ciphertext data through the multi-party secure computing system, and obtain the ciphertext of the operation result corresponding to the character string to be processed arts. The embodiment of the present invention can improve the generality of the data operation of the string type, and improve the efficiency of the data operation of the string type.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a data processing method, device and device for data processing. Background technique [0002] The MPC (Secure Multi-Party Computation, multi-party secure computing) system is used to solve the problem of secure multi-party collaborative computing in the absence of a trusted third party. The multi-party secure computing system requires the input data to be in the state of ciphertext, that is, in a distributed network, multiple participating entities each hold secret inputs, and all parties hope to jointly complete the calculation of a function, and each participating entity is required to divide the calculation No input from other participating entities will be available outside of the results. [0003] Currently, the types of input data that can be supported by the multi-party secure computing system usually include integer, fixed-point or floating-point types, but do...
