GatewayV2X: Interfacing V2X Wireless Sidelink with Zonal Vehicle Networks

GatewayV2X designs high-performance gateway architectures that route, filter, and translate external V2X messages into internal automotive bus protocols with hardware firewalls.

The Boundary Between Untrusted Wireless Airwaves and Vehicle Actuators

As the physical entry point for all over-the-air cooperative messages, the V2X gateway enforces strict protocol validation, cryptographic verification, and rate limiting before forwarding data to zonal controllers.

Core Engineering Areas

• V2X to CAN-XL & Ethernet Translation — High-throughput hardware-accelerated payload unpacking, serialization, and deterministic bus routing.
• Hardware Firewalls & DPI — Protecting internal ECUs against spoofed safety alerts, replay attacks, and denial-of-service floods.
• Zonal Architecture Integration — Architectures for routing time-critical telemetry over 10BASE-T1S and multi-gigabit Ethernet backbones.
