Researchers have developed a new cryptographic protocol called Heartbeat-Bound Hierarchical Credentials (HBHC) to address the safety gap in autonomous AI agent swarms. This protocol binds credential validity to periodic liveness proofs from parent agents, enabling rapid revocation without requiring network connectivity to a central authority. Experiments with GPT-4o-mini agent swarms demonstrated a significant reduction in the 'zombie agent' window, with zero post-revocation tool calls observed even under prompt injection attacks. AI
