摘要

The countermeasure process uses an encryption algorithm with an elliptical curve public key. Two random numbers are chosen providing an isomorphic elliptical curve and coordinate of a point found. An exponential algorithm is applied to find a second point, and the coordinates of an elliptical curve found. The countermeasure process uses an encryption algorithm with a public key with an elliptical curve defined by two characteristics. Two random numbers are chosen and coordinates of a point on an elliptical curve found. An exponential algorithm is then applied to find a second point.
