V2XKernel: Low-Jitter Real-Time Microkernels for Vehicular Communications

V2XKernel develops high-integrity operating system microkernels engineered specifically to execute mission-critical V2X communication stacks with guaranteed microsecond responsiveness.

Minimizing the Trusted Code Base for Safety-Critical Communications

Monolithic operating systems like standard Linux carry millions of lines of code, creating unacceptable attack surfaces and unpredictable scheduling delays. V2XKernel implements a minimal microkernel isolating drivers and network stacks in user-space memory.

Core Engineering Areas

• POSIX PSE52 Conformance — Standardized APIs enabling rapid porting of ETSI and SAE communication stacks.
• MPU & Spatial Isolation — Restricting memory write permissions so malicious or corrupted V2X packets cannot crash the kernel.
• Microsecond Interrupt Handling — Directing physical radio interrupts directly to dedicated real-time worker threads without latency jitter.
