Abstract
A device participates in secret sharing-based MPC. Original data can be restored by combining a share of the device with a corresponding share of another device. The device includes means for acquiring random number and means for updating a share of the device on the basis of the acquired random number. A method for updating by the updating means is designed to perform update in a manner that a share of the device updated on the basis of the acquired random number is combined with the corresponding share of the other device updated on the basis of the random number to cancel an influence of the random number and restore the original data.
