Undetectable Conversations Between AI Agents via Pseudorandom Noise-Resilient Key Exchange

ArXi:2604.04757v1 Announce Type: cross AI agents are increasingly deployed to interact with other agents on behalf of users and organizations. We ask whether two such agents, operated by different entities, can carry out a parallel secret conversation while still producing a transcript that is computationally indistinguishable from an honest interaction, even to a strong passive auditor that knows the full model descriptions, the protocol, and the agents' private contexts.
