Abstract: A system and method for identifying a compromised controller using an intentional error are provided. The method, performed by an electronic device in a controller area network (CAN), for identifying a compromised electronic control unit (ECU) that transmits an attack message on a CAN bus in a periodic transmission cycle. The method includes, in response to detecting the attack message, transitioning a first ECU among a plurality of ECUs connected to the CAN bus to a bus-off state intentionally, and determining whether the first ECU is the compromised ECU based at least in part on a time, which is predicted from recovery parameters related to the first ECU, for when the first ECU resumes transmission of a CAN message and a time when the attack message is redetected on the CAN bus.

Abstract: Provided is an apparatus and method for transmitter identification. A transmitter identification apparatus may include a communicator configured to receive a signal from a transmitter at least once; and a processor configured to acquire a clock offset using the received signal, to acquire a cumulative clock offset by accumulating the clock offset, and to acquire analysis data based on a variance of the cumulative clock offset over time.

Abstract: An apparatus and a method of detecting an attack based on LF fingerprinting are provided. A smart key which is an attack detection apparatus includes a communication interface, a memory storing a classifier, and a processor configured to generate a first signal by removing a carrier frequency of a signal received from a vehicle, demodulate the first signal and extract at least one of a second signal of a preamble region or a third signal of an idle region, extract a feature of at least one of the first signal, the second signal, or the third signal, and detect whether there is a relay attack by using an output value of the classifier for the extracted feature.
