Detect Denial of Service on an Open Embedded Automotive Platform
summary
Describes an open distributed embedded automotive testbed built from Raspberry Pi nodes (with IndustrialBerry CANberry Dual V2.1) and an Odroid XU3 gateway (using Scantool OBD Dev Kit USB‑to‑CAN with STN2120). It studies detection of CAN bus denial‑of‑service on the gateway by measuring per‑ID packet frequency, Cortex‑A15 core energy via INA231 over I2C, thermal zone gradients via I2C, and round‑trip times between RPI1 and RPI2, reporting that energy measurements gave the best detection accuracy and were used to trigger interface throttling or shutdown to protect ECUs.
