Abstract

The embodiment of the invention provides a data processing method and device and a device for data processing. The method comprises the steps that a calculation task is received, and the calculation task comprises a general calculation function; the privacy type of calculation data participating in the general calculation function is determined, the privacy type comprises a plaintext type or a ciphertext type, and the calculation data accords with a predefined general data type; according to the privacy type, a target calculation function conforming to the privacy type and an execution end corresponding to the target calculation function are determined, and the target calculation function comprises a plaintext calculation function or a ciphertext calculation function; and the target calculation function is executed through the execution end. According to the embodiment of the invention, the calculation efficiency can be improved on the basis of ensuring the data privacy security.

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 plaintext and ciphertext hybrid computing system is a system that can perform both plaintext and ciphertext calculations. [0003] Based on the plain-cipher text hybrid computing system, multi-party secure computing can be performed. Multi-party secure computing is a technique for securely computing a contracted function when computing participants do not share their own data and there is no trusted third party. Through secure algorithms and protocols, computing participants encrypt or convert plaintext data before providing it to other parties, and other computing participants cannot access other parties' plaintext data, thereby ensuring the security of all parties' data. [0004] The plaintext calculation function library and the ciphertext calculation function library...
