摘要：
A relay device 12 is provided which transfers a plurality of original data fragments corresponding to a plurality of secret sharing values of original data to a plurality of secure computation devices, transfers, to each of the secure computation devices, a request to send a result fragment based on a secure computation result corresponding to any one of the original data fragments, and transfers the result fragment. The relay device 12 controls timing with which the original data fragments are transferred and timing with which the request to send is transferred.
