LYNX MOSA.ic™
The Foundation for Mission-Critical Edge Computing
MOSA.ic accelerates safety certification for secure multi-core systems through a modular separation-kernel architecture that enables deterministic partitioning, mixed-criticality consolidation, and open systems integration.
What is LYNX MOSA.ic?
LYNX MOSA.ic™ is a modular software framework and architecture purpose-built for mission-critical edge computing. Based on the Modular Open Systems Approach (MOSA), it provides a flexible foundation for building secure, scalable, and certifiable embedded systems.
Rather than relying on a traditional monolithic operating system, MOSA.ic uses a high-assurance separation kernel to securely run multiple operating environments side-by-side on a single multi-core processor. This includes support for a real-time operating system (RTOS) and a lightweight unikernel, enabling developers to match the right runtime environment to each application.
This architecture ensures that highly critical, real-time functions remain fully isolated from lower-priority software, even while sharing the same hardware delivering strong security, mixed-criticality support, and a clear path to certification.
Key Benefits
Accelerated Certification: By leveraging a modular architecture and tightly scoped, purpose-built components such as unikernels, MOSA.ic helps reduce overall certification effort and streamline recertification when changes are required, enabling faster time to deployment with lower program risk.
Optimized for Multi-Core Processors: Designed to take full advantage of modern multi-core architectures while aligning with CAST-32A and AC 20-193 guidance. Organizations can consolidate mixed-criticality workloads onto shared multi-core platforms with strong partitioning and controlled resource management that minimizes interference risk and supports robust safety arguments.
Future-Proof Modularity: Because the architecture is highly modular, individual software components can be updated, reused, or swapped out independently. This prevents vendor lock-in, reduces program risk, and makes legacy systems cost-effective to upgrade.
Core Architecture
The MOSA.ic software framework is powered by three foundational technologies designed for absolute security and determinism:
LynxSecure (The Hypervisor)
LynxOS-178 (The RTOS)
LynxElement (The Unikernel)
