[curves] ECC introduction: point addition on simple Weierstrass form

[Dominik Pantůček]

Hello curves fans,

another article in my introductory series about elliptic curves used in
cryptography is out[1]. This time it is about point addition on elliptic
curve in simple Weierstrass form over R and GF(p). For those following
my discussion with Brad earlier, you can see the graphical
representation of infinite straight line over GF(p) torus in the
video[2] - around 0:45 it becomes closed. I would appreciate any
feedback regarding the article format, visualizations or anything else -
just, please, bear in mind that the intended audience are real beginners
and therefore I have omitted some things and want to explain them in the
future separately.


Cheers,

Dominik
