Lava Lamp Randomness – Daily Security Byte

Here’s a forgotten video from the vaults. This isn’t any big security incident or vulnerability, just news of a novel way one company creates seeds of randomness for their cryptographic algorithms. If you don’t know why randomness is important to cyrptography, or why computers struggle to be random, this video primer might help. Watch below to learn more about why lava lamps can help secure digital transactions. As an aside, I made this video weeks ago but forgot to post, so the references are older than the video suggests.
