摘要： A key management method serves as an electronic control unit (ECU) in an onboard network system having a plurality of ECUs that perform communication by frames via a network. The method includes storing a shared key, acquiring a session key, and executing encryption processing using the session key. The method further includes executing inspection of a security state of the shared key stored in a case where a vehicle is in at least one of the following particular states: the vehicle is not driving and is an accessory-on state; a fuel cap of the vehicle is open, and the vehicle is not driving and is fueling; the vehicle is parked, which is indicated by the gearshift; the vehicle is in a stopped state before driving, which is indicated by the gearshift; and a charging plug is connected to the vehicle, and the vehicle is electrically charging.

摘要： An electronic control unit is connected to a network in an in-vehicle network system. The electronic control unit includes a first control circuit and a second control circuit. The first control circuit is connected to the network via the second control circuit. The second control circuit performs a first determination process on a frame to determine conformity of the frame with a first rule. Upon determining that the frame conforms to the first rule, the second control circuit transmits the frame to the first control circuit. The first control circuit performs a second determination process on the frame to determine conformity of the frame with a second rule. The second rule is different from the first rule.

摘要： An electronic control unit is connected to an in-vehicle network bus in an in-vehicle network system. The electronic control unit includes a first control circuit and a second control circuit. The first control circuit is connected to the in-vehicle network bus via the second control circuit over wired communication and/or wireless communication. The first control circuit performs a first determination process on a frame to determine conformity of the frame with a first rule. The second control circuit performs a second determination process on the frame to determine conformity of the frame with a second rule, and, upon determining that the frame conforms to the second rule, transmits the frame to the in-vehicle network bus.

摘要： A vehicle network system employing a controller area network protocol includes a bus, a first electronic control unit, and a second electronic control unit. The first electronic control unit transmits, via the bus, at least one data frame including an identifier relating to data used for a calculation for obtaining a message authentication code indicating authenticity of transmission content. The second electronic control unit receives the at least one data frame transmitted vis the bus and verifies the message authentication code in accordance with the identifier included in the at least one data frame.

摘要： A security apparatus is provided that is connected to a bus. The security apparatus includes a receiver that receives a first frame from the bus, a memory that stores an examination parameter defining a content of an examination on the first frame, and processing circuitry that performs operations. The performed operations include first determining whether a predetermined condition is satisfied for the first frame. The performed operations also include, in a case where the first determining determined that the predetermined condition is satisfied, updating the examination parameter stored in the memory. The performed operations further include second determining whether the first frame is an attack frame based on the updated examination parameter stored in the memory.

摘要： A key management method serves as an electronic control unit (ECU) in an onboard network system having a plurality of ECUs that perform communication by frames via a network. The method includes storing, in a first-type ECU, a shared key to be mutually shared with second-type ECUs, and executing encryption processing regarding a framed transmitted or received via the network, based on the shared key. The method further includes executing, by the first-type ECU, inspection of a security state of the shared key stored by the second type ECUs in a case where a vehicle is in at least one of the following particular states, including immediately after the vehicle is not driving and is entering the accessory-on state, immediately after the vehicle is not driving and the vehicle is entering the accessory-off state, and immediately after the vehicle engine is started.

摘要： A security apparatus includes a receiver that receives a frame front at least one network, a parameter storage that stores at least one examination parameter defining a content of an examination on a frame, and processing circuitry that performs operations. The operations include judging whether a predetermined condition is satisfied for the frame received by the receiver. When the predetermined condition is satisfied, updating the stored at least one examination parameter, and when the predetermined condition is not satisfied, not updating the stored at least one examination parameter. The operations also include executing an examination, based on the stored at least one examination parameter, as to whether the frame received by the receiver is an attack frame, and performing a process depending on a result of the execution of the examination such that an influence of an attack frame on at least one electronic control unit is suppressed.
