Abstract

An apparatus computing scalar multiplication of a point on an elliptic curve by a scalar value includes an estimation unit configured to estimate a pre-computation amount based on the scalar value, a pre-computation unit configured to perform pre-computation based on the point on the elliptic curve by using the estimated pre-computation amount, a generating unit configured to generate an internal representation of the scalar value by using the estimated pre-computation amount, and a computation unit configured to output a result of the scalar multiplication of the point based on the result of the pre-computation and the internal representation.
