  • Patent number: 10764326
    Abstract: A CAN controller safe against a CAN-communication-based hacking attack includes each CAN controller that filters a message to be transmitted to a CAN bus. A corresponding CAN controller filters only a message having a valid transmission ID to be transmitted. The CAN controller safe includes a transmission buffer, a transmission filter unit, a protection memory and a filter value setting unit. The transmission buffer unit temporarily stores transmission data to be transmitted to a CAN bus. The transmission filter unit has message IDs allowed to be transmitted as a transmission filter, configured to search for a message ID of the transmission data in the transmission filter, and filter the transmission data. The protection memory stores one or more filter values of the transmission filter and the filter value setting unit is configured to fetch the filter value stored in the protection memory.

  • Publication number: 20200134186
    Abstract: Provided is an electronic control unit (ECU) security function setting system including an ECU and a tester connected to the ECU through a communication network. The tester includes a security function requester configured to request a security function loader to the ECU when the ECU is in a security function setting mode; an user authenticator configured to receive a user authentication request from the ECU and perform an user authentication; and a firmware transmitter configured to transmit stored security function firmware to the ECU when the user authentication is passed, and the ECU activates an instruction present in the received security function firmware and perform a security function setting.

  • Publication number: 20200120117
    Abstract: Provided is a CAN communication based abnormal message detection method including obtaining reception times of reception messages; a reception filtering operation for performing a period calculation for comparing a difference between reception times of reception messages having the same message ID and a reference period of the corresponding message ID; an abnormal message detecting operation for determining the reception messages as abnormal messages when, as a result of the period calculation, the difference between the reception times is smaller than the reference period and determining the reception messages as normal messages when the difference between the reception times is greater than the reference period; and a blocking operation for blocking the abnormal messages.

  • Patent number: 10373679
    Abstract: A method for reading data of a memory cell including a resistive memory element having a low resistance state and a high resistance state according to stored data and a selection element may include applying a recovery voltage to both ends of the memory cell, and applying a read voltage to both ends of the memory cell and sensing the data. The recovery voltage may be equal to or more than a second voltage obtained by adding a drift value of the memory cell to a first voltage for turning on the memory cell in a case in which the resistive memory element is in the low resistance state.
