What do you get when you cross cryptography with a wall of lava lamps? Believe it or not, a much more secure Internet. Cloudflare’s CTO John Graham-Cumming will explain why all our modern communications require sources of randomness to remain secure, and how his company has used a wall of 100 lava lamps to serve as a serious source of entropy. John will explain how to pick strong passwords using dice, how you can predict random numbers, and whether quantum computing will render all of our crypto technology useless.
