Secret product-sum calculation method, secret product-sum calculation system, calculation device, and program thereof

摘要

To be performed upon the secret convolutions by cooperation of calculation (computing device) a three-party, to calculate the high-speed and possible, to provide a method implementation is easy. Party X is running and a second calculation step party X and party X first calculation step and party X random number generation step, party Y is second calculation party and party Y Y first calculation step and party Y random number generation step In confidential calculation method to run a step, party Z is, to run a second calculation step party and Z party Z first calculation step and party Z random number generation step, it is symmetrically constructed the calculation processing of each party.
