WebTwo families of elliptic curves are used in cryptographic applications: prime curves over Z p and _____ over GF(2 m). We use a cubic equation in which the variables and coefficients all take on values in the set of integers from 0 through p - 1 and in which calculations are performed modulo p for a _____ over Z p. Webequation. By ﬁxing an integer c 2Z, we look for rational solutions to the Diophantine equation y2 x3 = c The solutions to these equations using real numbers are called cubic curves or elliptic curves, each of which is of the form y2 = ax3 +bx2 +cx +d but can be simpliﬁed into the Weierstrass form by substituting x = x b 3a: y2 = ax3 +bx +c
