摘　　要：The rapid expansion of intra-vehicle networks has increased the number of threats to such networks.Most modern vehicles implement various physical and data-link layer technologies.Vehicles are becoming increasingly autonomous and connected.Controller area network(CAN)is a serial bus system that is used to connect sensors and controllers(electronic control units-ECUs)within a vehicle.ECUs vary widely in processing power,storage,memory,and connectivity.The goal of this research is to design,implement,and test an efficient and effective intrusion detection system for intra-vehicle CANs.Classic cryptographic approaches are resource-intensive and increase processing delay,thereby not meeting CAN latency requirements.There is a need for a system that is capable of detecting intrusions in almost real-time with minimal resources.Our research proposes a long short-term memory(LSTM)network to detect anomalies and a decision engine to detect intrusions by using multiple contextual parameters.We have tested our anomaly detection algorithm and our decision engine using data from real automobiles.We present the results of our experiments and analyze our findings.After detailed evaluation of our system,we believe that we have designed a vehicle security solution that meets all the outlined requirements and goals.
