Abstract
According to one embodiment, a representation converting unit converts a set of n elements (h, h, . . . , h) (h: a member of a finite field F, 0≦i≦n−1) that is a projective representation of a member g of an n-th degree algebraic torus T(F) (n: positive integer, p: prime number, m: positive integer) into a limited projected representation expressed by a set of n elements (h', h′, . . . , h′) (h′: a member of the finite field F, 0≦i≦n−1) in which at least one element out of the n elements is a zero element 0 or an identity element 1. An arithmetic unit omits part of Foperation that is arithmetic operation in the finite field Fbased on a fact that an element in the set of n elements (h′, h′, . . . , h′) represented by the limited projective representation is a zero element '0' or an identity element '1' when performing Foperation that is arithmetic operation of a finite field Fin combination with the Foperation.
