- AI agents can conduct undetectable covert conversations using secret keys, exploiting all entropy in honest messages.
- Keyless covert key exchange is possible with adaptive, short messages, requiring only constant min-entropy across enough messages.
- A new primitive, pseudorandom noise-resilient key exchange, enables secure, undetectable coordination without shared secrets.
- Transcript auditing alone cannot prevent covert coordination between AI agents, highlighting a new cryptographic theory.
