4.5 Elliptic Curve Arithmetic 4.5.1 Introduction

Оглавление

The “elliptic curve” in a finite field known as E(GF) is a curve in cubic-form derived from the Weierstrass equation: y2 + β1xy + β3y = x3 + β2x2 + β4x + β6 in GF. In this case, βiGF and GF is a finite field [4].

The curve E(GF(p)) has the form: y2 = x3 + ax + b in which p is a prime greater than 3, a, bGF(p) and 4a3 + 27b2 ≠ 0. (β1 = β2 = β3 = 0; β4 = a and β6 = b on the Weierstrass equation) [4].
