An Introduction to Elliptic Curve Cryptography

Some of my research is focused on the implementation issues of Elliptic Curve Cryptography on embedded systems. Since I often have to explain what Elliptic Curve Cryptography exactly is, I decided to write this little introduction on the matter. Maybe this will get the attention of some of my students, and can perhaps get them more interested in the mathematical branch of finite fields in Algebra.

Last time we build up the basics of the raytracer: some essential math and the corresponding function implementations and structures in the C programming language. We will expand the ray tracer this time to generate actual graphics and to generate these images with multiple spheres, light sources, and reflections.

I've always been fascinated with computer graphics. One of the first things I learned to code when I was a kid was a ray tracer. It was a simple and straight-forward assembly implementation on an early home computer, but it taught me a lot about how computers deal with graphics and just programming in general and its connection to mathematics.
