This paper presents a new projective coordinate system and new explicit
algorithms which together boost the speed of arithmetic in the divisor class group of
genus 2 curves. The proposed formulas ge...
Double-and-Add with Relative Jacobian Coordinates
elliptic curve relative Jacobian coordinates co-Z coordinates

One of the most efficient ways to implement a scalar multiplication on elliptic
curves with precomputed points is to use mixed coordinates (affine and Jacobian).
We show how to relax these precondit...
