Arithmetic of the Group of Elliptic Curve Points

This section describes the Intel IPP functions that implement arithmetic operations with points of elliptic curves [EC]. The elliptic curve is defined by the following equation:
y
2
 =
x
3
 +
A
 ⋅
x
 +
B
where
  • A
     and
    B
     are the parameters of the curve
  • x
     and
    y
     are the coordinates of a point on the curve
This document considers elliptic curves constructed over the finite field GF(
p
) (prime or its extension), therefore the arithmetic of elliptic curves is based on the arithmetic of the underlying finite field. In the equation above,
A, B, x,
 and
y
 belong to the underlying field GF(
p
).
