Abstract

The invention discloses a secure multi-party computing method, an electronic device and a storage medium. The method comprises: a user node receiving a calculation request through a calculation contract, the calculation request comprising to-be-calculated data, and the calculation contract being deployed on a block chain; the user node splitting the to-be-calculated data into a plurality of piecesof sub-data by utilizing the calculation contract; the user node sending the first number of pieces of sub-data to different participation nodes in a participation node set by using a calculation contract; the user node receiving transaction information sent by the participation node by using the calculation contract, wherein the transaction information is obtained by calculating the sub-data bythe participation node under the condition that the sub-data is real; and the user node obtaining a final calculation result based on the transaction information by using the calculation contract. Inthis way, the data security can be improved.

Description

technical field [0001] The present application relates to the field of secure multi-party computing, in particular to a secure multi-party computing method, electronic equipment and storage media. Background technique [0002] With the advent of the era of big data, data becomes more and more important. And data needs to be calculated to reflect or realize its value. However, many users are considering information security or interests, and their data is often kept in a confidential state, forming islands of data. Therefore, in an environment where user data has no privacy, it is particularly important to confirm data rights and realize data value. [0003] Secure Multiparty Computation (MPC) is a computing protocol based on this purpose. During the execution of the entire computing protocol, users always have control over their personal data, and only the computing logic is public. The participants only need to participate in the calculation, and can complete the data ca...
