Computing method, device, electronic equipment and storage medium for mixed plaintext and ciphertext

Abstract

The present application provides a method, device, electronic equipment, and storage medium for mixed plaintext and ciphertext computing, and relates to the technical field of privacy computing. The method includes: a first plaintext node reading the first object of the first calculation data based on a first instruction; a second plaintext node creating a second object of the first calculation data based on the first instruction, the first The second plaintext node is a plaintext node other than the first node; the first plaintext node sends the first object to the ciphertext node based on the second instruction; when the first object of the calculation data required for calculation is received , the ciphertext node performs a logical operation on the first object of the required calculation data based on the third instruction, and creates the first object of the logical operation result based on the fourth instruction. This method allows multiple nodes to jointly maintain a virtual second object mechanism of a set of codes, ensures that multiple nodes run a set of codes together, and solves the problem that codes need to be written in a distributed manner.

Description

technical field [0001] The present application relates to the technical field of communication encryption, in particular, to a method, device, electronic equipment and storage medium for mixed plaintext and ciphertext calculations. Background technique [0002] In traditional mixed plaintext and ciphertext computing systems, users need to write codes in a distributed manner. If the user wants to perform calculations on the plaintext computing side, he needs to write plaintext codes, and if he wants to perform calculations on the ciphertext computing side, he needs to write ciphertext codes. At the same time, a control terminal is also needed to control the data transmission between the plaintext computing terminal and the ciphertext computing terminal. When data is transferred from the plaintext side to the ciphertext side, it is necessary to explicitly call the encryption function provided by the plaintext hybrid computing system; decryption function. During the developm...
