That’s an intriguing angle. Chaotic systems can give you raw noise, but they’re also extremely sensitive to initial conditions. For a secure key you need the output to be statistically uniform and hard to predict, which can be hard to guarantee with plasma turbulence alone. A better bet is to feed a well‑tested pseudorandom generator with a high‑entropy seed, then maybe inject a burst of the chaotic signal as a one‑time pad or entropy booster. I can run some tests on the turbulence data and see how it fares against NIST standards, but just relying on raw plasma noise might leave a pattern gap that an attacker could exploit.
