Device for checking performance of group of rational point of key generation variable, has unit for determining arrangement of group of rational points of Jacobian variable

摘要

The device (100) has a unit (110) for determining an arrangement of a group of rational points of a Jacobian variable. Another unit (120) for determining an arrangement of a group of rational points of an elliptical curve over the finite body. The elliptical curve is that curve, which carries fixed body of involution of a hyperelliptic curve, which is formed from a morphism (f) that belongs to the involution. An independent claim is also included for a method for checking a performance of a group of rational point of a key generation variable.
