A system and a method of providing security to an in-vehicle network are provided. The method efficiently operates multiple detection techniques to maintain robustness against malicious message detection while increasing overall detection efficiency.

System and method for providing security to in-vehicle network

A control method of a vehicle by a first controller and a second controller, the control method includes: generating, by the first controller, an Ea(B) in which a second symmetric key is encrypted based on a first symmetric key, and assigning a first random number to the Ea(B); receiving, by the second controller, the Ea(B) and the first random number, generating a fourth symmetric key in which the Ea(B) is decrypted based on a third symmetric key, and generating an Eb(N(MASTER)) in which the first random number is encrypted based on the fourth symmetric key; receiving, by the first controller, the Eb(N(MASTER)), and decrypting the Eb(N(MASTER)) to generate a second random number; and updating the second symmetric key based on a comparison between the first random number and the second random number.

Method of controlling security key of vehicle

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.

System and method for identifying compromised electronic controller using intentionally induced error

A system and a method of providing security to an in-vehicle network are provided. The method efficiently operates multiple detection techniques to reduce the required system resources while maintaining robustness against malicious message detection.
