Does the uFAI have access to it's own public key? If so, I think it can produce coherent output.

All it has to do is encrypt random things with the public key, until it finds something that produces coherent-looking ciphertext from it's own perspective, and then there's a two-way channel.

Isn't "encrypt random things with the public key, until it finds something that produces [some specific] ciphertext" exactly what encryption is supposed to prevent?? :)

(Not all encryption, but commonly)

In RSA, it is easy to find a message whose encryption begins with "001001," for example.
