Implementing Elliptic Curve Cryptosystems. – A Survey by Mario Schmitz, Massey University, February 2005


  1. Projective Plane requires less multiplication compared to Affine Plane
  2. No invers operation in Projective Plane
  3. Projective Plane requires more memory as more temporary results to be saved
  4. In defining point of infinity, Projective Plane gives a more natural way to programmer to deal with it
