Diffie-Hellman Key Exchange graphically explained – Wikipedia/Computerphile
Posted by jpluimers on 2019/12/31
Sometimes a picture or video is better than a thousand words.
I wish that back when I learned about the mathematics of the Diffie–Hellman key exchange – Wikipedia
I had seen the picture on the right from File:Diffie-Hellman Key Exchange-modified.png – Wikipedia (via DHKE General overview) which inspired the Computerphile and Art-Of-The-Problem videos below doing the same dynamically with colorised liquids and paint.
Art-Of-The-Problem has a similar video on RSA as well which is also below.
Usually Diffie-Hellman is combined with RSA to prevent man-in-the-middle and allow for perfect forward secrecy. That’s what the final computerphile video is about.
Excellent!
Finally, Computerphile also posted a video with the mathematics. If you’re into that: nice work too!
