Embodiment Construction

[0062] In practical applications, for the purpose of privacy protection, multi-party secure computing algorithms are usually black-box algorithms, and the data transmission behavior between computing nodes equipped with multi-party secure computing algorithms is very opaque;

[0063] For example, between computing nodes equipped with multi-party secure computing algorithms such as secret sharing, homomorphic encryption, and obfuscated circuits, interactive messages carrying a large amount of ciphertext and / or random numbers are usually transmitted, even for users of multi-party secure computing algorithms It is also difficult to understand the specific meaning of the ciphertext and / or random numbers carried in the above interaction messages.

[0064] Therefore, for the provider of the multi-party secure computing algorithm, in order to prove that the multi-party secure computing algorithm it provides is transparent and credible, it has to share the source code of the multi-part...

Abstract

A multi-party secure computing method is applied to any computing node deployed in a distributed network. Wherein a plurality of computing nodes are deployed in the distributed network, and the plurality of computing nodes jointly participate in multi-party secure computing based on the privacy data held by the plurality of computing nodes, wherein the method comprises the following steps of: generating computing parameters related to the held privacy data based on a multi-party secure computing algorithm; Sending the computing parameters to other computing nodes participating in the multi-party security computing to perform the multi-party security computing by the other computing nodes based on the collected computing parameters sent by each computing node participating in the multi-party security computing; And creating an audit log corresponding to the calculation parameter; Wherein the audit log records description information related to the calculation parameter.

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...
