Abstract

The invention provides a secure multi-party calculation implementation method and device, a computer device and a storage medium. The method comprises the steps that a proxy server receives a calculation request sent by a first MPC node, wherein the first MPC node is one MPC node in a plurality of MPC nodes, and a callback function of each MPC node in the plurality of MPC nodes is registered in the proxy server; in response to the calculation request, the proxy server sends the calculation request to each MPC node by calling the callback function of each MPC node; and under the condition thatit is determined that each MPC node receives a calculation request, the proxy server sends a calculation start notification to each MPC node by calling the callback function of each MPC node, whereinthe calculation start notification is used for indicating each MPC node to execute the safe multi-party calculation. According to the above method, the secure multi-party calculation cooperation service can be constructed in a more flexible and configurable manner, and the task cooperation efficiency and the calculation efficiency are effectively improved.

Description

technical field [0001] The present application relates to the technical field of secure multi-party computing, and in particular to a method, device, computer equipment and storage medium for implementing secure multi-party computing. Background technique [0002] Secure Multi-Party Computation (MPC) means that in a distributed network, multiple users need to work together to complete a task. Each user holds some private data as the input of the task, and they hope to complete it together. The calculation of these data also requires each user not to know any input information of other users except the calculation results. Secure multi-party computing is to solve the problem of collaborative computing between a group of participants who do not trust each other under the premise of protecting privacy. Secure multi-party computing must ensure the independence of inputs and the correctness of calculations, while not disclosing each input data to participants other members of th...
