I’ve been thinking about a concept that mixes LLMs with public-key style communication, and I’m trying to understand whether it has any real cryptographic value or if it’s fundamentally flawed.

Idea:

• Each client generates a private/public key pair.
• Public keys are exchanged like in PKI/HTTPS.
• A special LLM acts as the encoder/decoder mechanism.

To send a message:

• Sender provides the plaintext + their private key to the LLM.
• The LLM outputs a natural-language “slop text” that does not obviously contain the original message.

To decode:

• Receiver provides the slop text + sender’s public key to the LLM.
• The LLM reconstructs the original plaintext.

The intention is not classical ciphertext, but semantically transformed text that looks harmless or unrelated.

Curious whether this is nonsense, already explored, or potentially an interesting direction.

Is there existing research close to this idea?
