Abstract: Certain aspects of the disclosure are directed to methods and apparatuses of intrusion detection for integrated circuits. An example apparatus can include a wired communications bus configured and arranged to carry data and a plurality of integrated circuits. The plurality of integrated circuits can include a first integrated circuit configured and arranged to operate in a scan mode during which the first integrated circuit performs a scan test to detect one or more faults in circuitry of the plurality of integrated circuits. The plurality of integrated circuits can further include a second integrated circuit configured and arranged to operate in a mission mode and supervise data traffic by monitoring communications including data patterns and accesses on the wired communications bus. In response to identifying a suspected illegitimate access, the second integrated circuit can perform a security action to mitigate a suspect illegitimate action in the plurality of integrated circuits.

Abstract: A method includes generating a target map indicative of objects around the vehicle using sensor data from sensor circuitry of the vehicle, the sensor circuitry including at least one radar sensor; and determining, by processing circuitry, if the vehicle is being towed away. Determining if the vehicle is being towed away can include comparing the target map to a previously obtained target map, determining if the vehicle is moving based on the comparison, and in response to determining the vehicle is moving, outputting an alarm message indicative of the vehicle being towed away.
