Operations of Points on Elliptic Curve in Projective Coordinates

摘要

In this article, we formalize operations of points on an elliptic curve over GF(p). Elliptic curve cryptography [7], whose security is based on a difficulty of discrete logarithm problem of elliptic curves, is important for information security. We prove that the two operations of points: compell_ProjCo and addell_ProjCo are unary and binary operations of a point over the elliptic curve.
