ZTASP: A Zero-Trust Governance Platform for Autonomous Systems

The Zero Trust Autonomic System Platform (ZTASP) is a mission-scale assurance and governance platform designed for autonomous systems operating in real-world environments. It integrates heterogeneous systems—including drones, robots, sensors and human operators—into a unified zero-trust architecture.

Unlike an autonomy algorithm stack, ZTASP functions as a governance layer that couples a chip-to-cloud trust architecture to ensure the integrity of autonomous operations. The platform treats various components as first-class zero-trust nodes, including unmanned aerial vehicles (UAVs), unmanned ground vehicles (UGVs), quadrupeds, and micro-scout robots.

The architecture also incorporates fixed infrastructure sensors and controllers. Human operators are integrated into this secure framework via wearables and First Responder Unit (FRU) rigs.

Real-Time Assurance and Reasoning

ZTASP utilizes two primary mechanisms to maintain operational safety and integrity: Secure Runtime Assurance (SRTA) and Secure Spatio-Temporal Reasoning (SSTR).

SRTA is responsible for enforcing safety constraints on autonomous agents in real time. This process draws on safety-wrapper architectures, runtime monitoring, and formal verification to ensure that agents operate within predefined safety boundaries.

SSTR enables context-aware decision-making across the platform’s heterogeneous systems. This allows for coordinated operations between drones, ground robots, sensors, and humans, providing a more resilient alternative to conventional coordination approaches.

Together, these components allow ZTASP to continuously verify system integrity and enable resilient operation, even when the system is functioning under degraded conditions.

Zero Trust at the Edge

The platform is designed to replace perimeter-based security models, which are often inadequate for governing distributed autonomous systems. ZTASP implements zero-trust principles, specifically continuous verification and least-privilege access, which are essential for multi-agent environments operating at the edge.

By moving away from the assumption that internal network traffic is inherently trusted, the platform reduces vulnerabilities associated with traditional security perimeters in complex, distributed deployments.

Deployment and Technical Readiness

ZTASP has progressed from conceptual design to operational validation. The platform has achieved Technology Readiness Level (TRL) 7 in mission-critical environments.

Some core components of the platform have reached even higher maturity levels. The Saluki secure flight controllers have reached TRL 8 and are already deployed in customer systems.

Although ZTASP was initially developed for high-consequence mission environments, the assurance and governance challenges it addresses are increasingly relevant in other sectors. These include critical infrastructure, transportation, and healthcare, where the secure management of autonomous systems is becoming a necessity.
