The Simple Brilliance of Modern Encryption | Diffie-Hellman Key Exchange

Diffie-Hellman Key Exchange is the first ever public-key encryption method, which is the core paradigm used for communication on the internet today. Amazingly, it is possible to send private data over public networks in a manner that is practical, efficient, and most importantly, secure! This is the first video in a series about modern encryption, where I show you how some of the most technical encryption schemes are a lot simpler than you might think, and can actually be thought of using analogies with physical real-world objects, such as mixing colors of paint together or making a transaction with a padlocked box. The actual implementations of modern encryption protocols involve some beautiful mathematics -- here we take a high-level approach and view the relevant math as a tool that implements the core concepts which make modern encryption possible. We cover two early encryption schemes, Caesar ciphers and One-Time Pads, before delving into the Diffie-Hellman Key Exchange algorithm. In the next video, I cover RSA encryption, and its unique advantages that further improve upon Diffie-Hellman Key Exchange.
