Modern automobiles have several processing elements called Electronic Control Units (ECUs) that control different functionalities in a vehicle. ECUs run various types of automotive applications such as anti-lock braking control, cruise control, and so on. Most of these automotive applications have strict timing (deadline) and latency constraints, and thus they are classified as hard real-time applications. The ECUs on which these applications execute are distributed across the vehicle and communicate with each other by exchanging messages. These messages can be classified as either time-triggered or event-triggered. Time-triggered messages are periodically generated messages originating from safety-critical software applications. In contrast, event-triggered messages
are generated asynchronously when a specific event occurs, typically by low-priority (e.g., maintenance) applications. The diverse nature of messages in automotive systems requires unique communication protocols and robust networks to support them. The advent of Advanced Driver Assistance Systems (ADAS) in vehicles has resulted in an increase in the number of ECUs, which in turn has increased the complexity of the in-vehicle network and the entire automotive system. It is projected that in the near future, improving ADAS effectiveness will require connecting to external systems using vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) protocols. This increased connectivity will make vehicle networks more vulnerable to sophisticated security attacks.
The research objective of this project is design novel scheduling, allocation, and adaptive management techniques to support secure, real-time, and fault-tolerant communication of messages across automotive networks. The project also involves aspects of anomaly detection using machine learning techniques, to counter attackers targeting automotive networks. The focus is on adapting and deploying these strategies on automotive network standards such as CAN, Flexray, and TTEthernet.
