Abstract
A share generating device obtains N seeds s, . . . , s, obtains a function value y=g(x, e)∈Fof plaintext x∈Fand a function value e, and obtains information containing a member yand N−1 seeds s, where d∈{0, . . . , N−1} and d≠i, as a share SSof the plaintext x in secret sharing and outputs the share SS. It is to be noted that the function value y is expressed by members y∈F, . . . , y∈Fwhich satisfy m=m(0)+ . . . +m(N−1).
