The authors designed Codetta for asymmetric multi-agent settings where agents do not share private randomness.
Codetta protocol enables high-capacity, keyless, undetectable steganography for LLM agents
The scheme combines a shared public model, sampling mechanism, and adaptive error-correcting code, achieving up to 94 times the capacity of prior asymmetric protocols.

Thread:Agent Covert Communication
Qi Pang, Virginia Smith, and Wenting Zheng propose Codetta, a steganographic protocol that allows independently deployed LLM agents to communicate covertly without a pre-shared key.
