摘要：
This paper proposes a coordinate system in which a point (x, y) is represented as (X, Y, Z, W), where x = X/Z and y = Y/W are satisfied. In the proposed coordinate system, the cost of scalar multiplication, which is the dominant operation of elliptic curve cryptosystems, on the twisted Edwards curve +/- x(2) + y(2) = 1 + dx(2)y(2) is the same as the existing lowest cost in a mixed coordinate system, and implementation of scalar multiplication becomes easier.
