  • Publication number: 20170126711
    Abstract: The present disclosure provides a vehicle controller area network (CAN) communication attack detection method and apparatus. The apparatus includes: a learning module, a profiling module, and a detection module. The learning module identifies a CAN identifier (ID) upon receiving a predefined CAN packet and generates learning statistical information expressed as bits with respect to a data field corresponding to the identified CAN ID. The profiling module maintains the learning statistical information received and a precollected attack type, and the detection module extracts a CAN ID and a bit stream of a data field from a real-time input CAN packet. In addition, the detection module configures a neural network by acquiring the learning statistical information from the profiling module, inputs the extracted bit stream to the configured neural network, and determines whether attack is detected, based on an output value of the neural network.
