Multi-party safety calculation method and device, and electronic equipment

Abstract

A multi-party secure computing method is applied to any computing node deployed in a distributed network. A plurality of computing nodes are deployed in the distributed network, and the plurality of computing nodes participate in the multi-party secure computing together based on the privacy data held by the plurality of computing nodes respectively; Wherein the computing node is corresponding toa trusted key source; The method includes obtaining a trusted key from the trusted key source; Encrypting the held privacy data based on the obtained trusted key to obtain ciphertext data; sending atleast the ciphertext data as computational parameters to other computational nodes participating in the multi-party security computation to perform the multi-party security computation by the other computational nodes based on the collected computational parameters sent by each computational node participating in the multi-party security computation.

Description

technical field [0001] One or more embodiments of this specification relate to the field of distributed computing, and in particular to a multi-party secure computing method and device, and electronic equipment. Background technique [0002] Multi-party secure computing is a cryptographic technology. Multiple parties participating in the calculation can perform a multi-party secure computing algorithm based on their own input data to jointly perform secure calculations and obtain a calculation result without disclosing the holding data to other parties. Some input data. [0003] Although multi-party secure computing algorithms can protect private data, incorrect or even malicious algorithm implementations may still leak private data. Ideally, all parties can develop their own multi-party secure computing software, and use their own multi-party secure computing software to participate in multi-party secure computing. However, in practical applications, all parties usually u...
