SECURE CALCULATION METHOD, SYSTEM AND APPARATUS FOR MULTI-PARTY DATA, AND STORAGE MEDIUM

A secure calculation method, system and apparatus for multi-party data, and a computer-readable storage medium. The method comprises: decomposing original data; allocating the decomposed original data to different calculation servers; respectively calculating split data in each different calculation server according to a corresponding monomial; adding a server random number to each calculation result; solving an intermediate result by a solving server, so as to obtain a simplified third intermediate result; and finally, sending the simplified third intermediate result to a demand terminal, so that the demand terminal performs final resolving to obtain a final calculation result. Therefore, any party participating in calculation does not need to provide original data for other parties participating in calculation, thereby solving the problem of trust between participants; the secure calculation of multi-party data can be completed without local original data being out, thereby not relying on the security of a
