Cryptography thread

What if there were a method of enabling data to be sent using an "absolutely unbreakable" one-time communication technique? What if that technique could achieve perfect secrecy cryptography via correlated mixing of chaotic waves in an irreversible time-varying silicon chip?

I am a nigger

One-time-pad then just delete the secret key.
Literally impossible to decrypt.
