Sovereign Execution Brokers: Enforcing Certificate-Bound Authority in Agentic Control Planes
This paper introduces the Sovereign Execution Broker (SEB), a new runtime enforcement boundary designed to secure autonomous agents. SEB ensures that agent actions are authorized by certificates and adhere to defined execution contracts, preventing non-deterministic reasoning processes from directly controlling critical workflows. The system separates proposal, admission, and execution phases, creating a short-lived, auditable capability for certified authority. A prototype implementation was evaluated on AWS and Kubernetes, measuring performance and security under various conditions. AI
IMPACT Enhances security and auditability for autonomous agents in production environments.
