Abstract
A random number generating unit generates a random number t. An elliptic curve setting unit defines an elliptic curve E: y{circumflex over ( )}2=x{circumflex over ( )}3−3x+t. An elliptic curve finitude judging unit judges whether orders m and m of respective elliptic curves Ep and Ep produced by reducing the elliptic curve E on a rational number field modulo primes p and p are 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.
