発明の名称 (英語) RATIONAL POINT INFORMATION COMPRESSION DEVICE, RATIONAL POINT INFORMATION COMPRESSION METHOD, AND RATIONAL POINT INFORMATION COMPRESSION PROGRAM
発明の概要(英語) Provided are a rational point information compression device, a rational point information compression method, and a rational point information compression program which compress and restore rational point information for a rational point group with an embedded degree of 1. With an additive group formed of rational points on an elliptical curve defined over a finite field Fp of a characteristic P designated E(Fp), and sets of rational points having a composite number order r, i.e., subgroups of the additive group, designated G1 = E(Fp)[r] and G2 = E(Fp)[r], rational points P member G1 and Q member G2 are compressed into the rational point R by the formula R = P + Q when being transmitted, and the rational point R is factored and restored into the rational points P and Q at the receiving end, thus shortening the data length involved in transmission and reception.
