Multi-party secure computing method and device, electronic equipment

Abstract

A multi-party secure computing method, applied to any computing node deployed in a distributed network; the distributed network deploys multiple computing nodes, and the multiple computing nodes jointly participate in multi-party secure computing based on private data held by them ; Wherein, the computing node is connected to a trusted key source; the method includes: obtaining a trusted key from the trusted key source; based on the acquired private data held by the trusted key pair Encrypt to obtain ciphertext data; at least send the ciphertext data as calculation parameters to other computing nodes participating in the multi-party secure computing, so that the other computing nodes can use the data collected by the computing nodes participating in the multi-party secure computing. Computational parameters perform multi-party secure computations.

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...
