Edwards curve information


Edwards curves of equation x2 + y2 = 1 + d ·x2·y2 over the real numbers for d = −300 (red), d = −8 (yellow) and d = 0.9 (blue)

In mathematics, the Edwards curves are a family of elliptic curves studied by Harold Edwards in 2007. The concept of elliptic curves over finite fields is widely used in elliptic curve cryptography. Applications of Edwards curves to cryptography were developed by Daniel J. Bernstein and Tanja Lange: they pointed out several advantages of the Edwards form in comparison to the more well known Weierstrass form[example needed].
