## Elliptic Curve Cryptography: finite fields and discrete logarithms

This post is the second in the series ECC: a gentle introduction.In the previous post, we have seen how elliptic curves over the real numbers can be used to define a group. Specifically, we have defined a rule for point addition: given three aligned points, their sum is zero ($P + Q + R = 0$). We have derived a geometric method and an algebraic method …
