摘要： An in-vehicle authentication system has a vehicle communication apparatus (100) that is provided in a vehicle equipped with a plurality of ECUs and that communicates with each ECU of the plurality of ECUs. An authentication part (101) performs configuration authentication for authenticating validity of a configuration for each ECU, and registers an ECU that has failed the configuration authentication in an authentication error list. A determination part (102) determines an in-vehicle function that is realizable in the vehicle based on the authentication error list and a function correlation table which indicates correlation between an in-vehicle function realized in the vehicle and an ECU used to realize the in-vehicle function. A display part (107) displays the in-vehicle function determined to be realizable in the vehicle by the determination part (102) on a display (805).

摘要： A storage unit stores message information in which a vehicle state, a message attribute that specifies a message to be communicated, and permission information on communication of the message specified by the message attribute are associated with one another. A protocol conversion unit acquires, as a communication message, a message to be communicated between an in-vehicle system and an external system. Based on a message attribute that specifies the communication message, a current state which is a current state of a vehicle, and the message information, a determination unit determines whether communication of the communication message is permitted when the vehicle is in the current state.

摘要： An attack detection device (501) includes a group generation unit (30), a log management unit (40), an authenticator generation unit (90) and a graph management unit (60). The group generation unit (30) generates an authenticator graph (D36) including a plurality of pieces of correspondence information wherein a plurality of logs and an identifier to identify an authenticator generated by using the plurality of logs are associated. The log management unit (40) manages the plurality of logs used for generation of an authenticator identified by the identifier in the authenticator graph (D36). The authenticator generation unit (90) generates the authenticator identified by the identifier for each identifier in the authenticator graph (D36) from the plurality of logs. The graph management unit (60) manages the authenticator graph (D36) and the authenticator generated.

摘要： A management domain unit is connected, via an independent virtual network (95) using a hypervisor unit, to a separate management domain unit (B) (10B) of a separate electronic control unit ECU (B) (1) having the separate management domain unit (B) (10B) and a separate basic domain unit (A) (50B) which substitutes for a basic domain unit. When an abnormality of the basic domain unit is detected, the management domain unit halts operation of the basic domain unit, and causes the separate management domain unit (B) (10B) possessed by the separate electronic control unit ECU (B) (1) to start operation of the separate basic domain unit (A) (50B).

摘要： A waveform analysis unit (102) analyzes a measured waveform which is a waveform obtained by measuring one of a voltage value and an impedance value of a bus line (300). A device authentication unit (104) determines whether or not a new device is connected to the bus line (300), the new device being a device not included in configuration information (1070) which includes one or more devices known to be connected to the bus line (300), performs authentication for each of the devices connected to the bus line (300), and when the new device is connected to the bus line (300), acquires authentication information used for the authentication for the new device, and performs the authentication for the new device. An illegitimate operation determination unit (105) determines whether or not illegitimate operation is performed on the bus line (300), by using the configuration information, an analysis result from the waveform analysis unit (102), and an authentication result from the device authentication unit (104).
