Secure wireless vehicle monitoring and control

The availability of real-time CAN-ECU data and the emerging vehicular networks are critical for advanced vehicle monitoring and control. This paper presents our integrated info-security scheme, real-time hardware/software solutions and their application scenarios. The core is the Integrated Info-Security Circuit Board to communicate with ECUs and sensors inside a vehicle through CAN Bus, LIN Bus, FlexRay and MOST Bus with wire interfaces, and to communicate with other vehicles, road-side infrastructure and mobile phones with wireless interfaces. We have built the first prototype with two circuit boards which communicate directly with CAN network and process CAN messages. One circuit board is used for monitoring and control Vehicle Functions via real-time CAN messages, while another circuit board is used to monitoring and control vehicle itself to against the theft. The demonstrations in the first prototype show that our solutions work very well.
