Today’s digital landscape, encryption stands as the foundation of secure communication, protecting everything from private messages to financial transactions. The strength of that encryption hinges on one critical factor: the randomness of the keys it uses. This paper proposes an unconventional yet compelling idea—tapping into the chaotic, unpredictable electric arcs produced by a Tesla coil as a physical source of randomness, or entropy. By capturing these dazzling arcs with high-resolution, high-speed cameras and converting the resulting visual data into cryptographic keys, we outline a hardware-based approach to elevate the quality of randomness in encryption systems. This method offers a fresh alternative to conventional software-based random number generators or other physical entropy sources, like the famous lava lamps used in LavaRand. With the potential to enhance both the security and uniqueness of cryptographic keys, this concept invites us to rethink how we generate the building blocks of digital protection.
