Title:
SECURE MULTI-PARTY COMPUTATION SYSTEM AND METHOD FOR SECURE DATA SHARING
Document Type and Number:
WIPO Patent Application WO/2023/216404
Kind Code:
A1
Abstract:
Disclosed in the present invention are a NODE ID-based secure multi-party computation system and method for secure data sharing. Data nodes, computation nodes and result nodes are respectively provided with a NODE ID, and the computation nodes are provided with PARTY IDs; each data node establishes a network connection with all the computation nodes, so as to form a data input network; each computation node establishes a network connection with the other computation nodes, so as to form a prediction/training network; and each computation node also establishes a network connection with all the result nodes, so as to form a result reconstruction network. By means of the present invention, a secure multi-party computation protocol supports any number of data providers and result receivers; the control over node data input, training/prediction and result reconstruction permissions is realized; the creation of a node network topology structure in MPC is realized; and all nodes in the MPC execute the same script to complete the whole process of data input, training/prediction and result reconstruction.
