> The ECDLP involves finding the integer k such that P=k⋅G, where P is a point on the curve, G is a known point (the generator point), and k is the ephemeral key. The difficulty of this problem is what makes ECC secure. I am trying to match up the statement above with the visualization directly below it where they show the generator point, G, on the curve. The plot shows k, the ephemeral key, as another point-- but it's NOT an integer, k is a point! And then there's a Q, which is the public key, and that's not described in the paragraph above at all. Nor is P shown in the plot. I don't get it?
