ABSTRACT:
A random number generating unit generates a random number t. An elliptic curve setting unit defines an elliptic curve E: y^2=x^3−3x+t. An elliptic curve finitude judging unit judges whether orders m1and m2of respective elliptic curves Ep1and Ep2produced by reducing the elliptic curve E on a rational number field modulo primes p1and p2are relatively prime. An elliptic curve order computing unit computes an order of the elliptic curve E. An elliptic curve condition judging unit judges the security of the elliptic curve E based on the computed order.
