Bunker-Centric Architecture
Secure Hypervisor-Based Architecture for Embedded Systems
Bunker-Centric Architecture is a multi-domain, hypervisor-based architecture for Embedded Cyber-Physical Systems and Physical AI Systems that require the highest levels of security, safety, and resilience. At its core, it provides a strongly isolated execution environment (“Bunker”), enforced by a secure hypervisor that combines near-native execution efficiency with innovative security mechanisms.

About Bunker-Centric Architecture
Bunker-Centric Architecture enables critical and non-critical workloads to safely coexist on the same hardware while maintaining strict isolation of assets, data, memory, peripherals, and execution domains. The architecture is designed for cyber-physical systems, including Industrial IoT (IIoT), automotive Electronic Control Units (ECUs), medical devices, robotics, autonomous systems, and other embedded platforms where protecting critical assets, ensuring operational continuity, and preserving the availability of critical functions are essential even when the system is under attack.
Its innovative architecture provides strong isolation guarantees while minimizing the trusted computing base, enabling secure execution of software inside the Bunker irrespective of the behavior of non-critcal software. Bunker-Centric Architecture supports the development of highly secure embedded platforms aligned with modern cybersecurity, facilitating compliance with regulatory and industry standards such as Cyber Resilience Act (CRA), IEC 62443, ISO/SAE 21434, and other domain-specific security frameworks.
