Sovereign Execution Brokers: Enforcing Certificate-Bound Authority in Agentic Control Planes

Summary

The Sovereign Execution Broker (SEB) is introduced as a runtime enforcement boundary designed for certificate-bound agentic infrastructure, addressing the risk of production mutation authority residing within non-deterministic autonomous agents. Existing access control and assurance layers are insufficient alone. SEB consumes certificates from a Sovereign Assurance Boundary (SAB), verifies requested mutations against certified execution contracts, checks validity windows, policy/revocation epochs, and live-state drift. It then mints scoped execution identity, invokes infrastructure APIs, and records signed decision and outcome records. This mechanism transforms certified authority into a short-lived, revocable, and auditable runtime capability, provided production mutation APIs reject non-broker identities. A prototype was evaluated on AWS and Kubernetes clusters, measuring latency, revocation propagation, drift detection, and security under fault injection.

Key takeaway

For AI Security Engineers deploying autonomous agents with infrastructure access, the Sovereign Execution Broker (SEB) offers a critical enforcement boundary. It ensures that non-deterministic agent reasoning processes cannot directly mutate production systems, instead enforcing certificate-bound, short-lived authority. You should investigate integrating SEB to enhance auditability, control, and security, especially when managing agentic control planes on platforms like AWS or Kubernetes, to mitigate risks associated with agent autonomy.

Key insights

SEB enforces certificate-bound authority for autonomous agents at the point of infrastructure mutation, separating proposal, admission, and execution.

Principles

• Production mutation authority should not reside inside non-deterministic reasoning processes.
• Separating proposal, admission, and execution creates short-lived, revocable, auditable runtime capability.

Method

SEB consumes SAB certificates, verifies mutation contracts, checks validity/epochs/drift, mints scoped identity, invokes APIs, and records outcomes.

In practice

• Deploy SEB as a runtime enforcement boundary for agentic infrastructure.
• Configure production mutation APIs to reject non-broker identities.
