Sovereign Execution Brokers: Enforcing Certificate-Bound Authority in Agentic Control Planes
A security checkpoint that stops AI agents from making unauthorized changes to cloud systems
Autonomous agents controlling cloud infrastructure need a hard stop between decision and action. This paper introduces the Sovereign Execution Broker, a system that sits between an AI agent's proposed changes and the actual infrastructure, verifying that each change matches what was explicitly approved and hasn't been revoked—then recording exactly what happened. The authors tested it on AWS and Kubernetes clusters and found it adds minimal latency while catching unauthorized mutations.
As AI agents gain direct control over production systems, a single compromised or hallucinating agent could cause widespread damage before anyone notices. This broker creates a tamper-proof record and a mandatory verification point that can't be bypassed, letting companies revoke agent permissions instantly and audit every change. In regulated industries like finance and healthcare, having a signed, auditable trail of who authorized what change and when could be legally required.
