Abstract
A public value 2/m is obtained, and secure computation of public value division [x]/(2/m) using a secret share value [x] and the obtained public value 2/m is performed, so that a secret share value [mx]of a value obtained by right-shifting mx by σ bits is obtained and output. Here, x is a real number, [•] is a secret share value of •, σ is a positive integer that is the number of bits indicating a right shifting amount, and m is a real number.
