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.

Book: The Code Book: The Science of Secrecy from Ancient Egypt to Quantum Cryptography

Carey Parker began programming computers in middle school when personal computers were just starting to become popular. For years, these twin interests percolated until he attended Purdue University and he learned you could get paid to do this stuff – it was called Electrical Engineering! After obtaining a bachelor’s and a master’s degree in EE, Carey wrote software for multiple companies, large and small. In recent years, particularly after the Edward Snowden revelations in 2013, he became deeply concerned about computer security and privacy. In 2014, he combined his passion for computers, cybersecurity and fantasy novels with the long-time desire to write the book: Firewalls Don’t Stop Dragons.
