Abstract: An electronic control unit connected to a bus of a first network where first-type frames are transmitted following a first communication protocol and a second network where second-type frames are transmitted following a second communication protocol in an onboard network system. The electronic control unit sequentially receives the first-type and the second-type frames from the bus and the second network respectively, and stores in first and second reception buffers, respectively. The electronic control unit sequentially generates first-type data and second-type data by referencing the contents of the first reception buffer and the second reception buffer, and stores the first-type and second-type data in first and second transmission buffers, respectively. The first-type data is traveling control data for a vehicle, and the second-type data is other data. The first-type or second-type data that is priority type data is transmitted with priority.

Abstract: A fraud detecting method for use in an in-vehicle network system including a plurality of electronic control units that communicate with each other via a network includes detecting whether a state of a vehicle satisfies a first condition or a second condition, and switching, upon detecting that the state of the vehicle satisfies the first condition or the second condition, an operation mode of a fraud-sensing electronic control unit connected to the network between a first mode in which a first type of detecting process for detecting a fraudulent message in the network is performed and a second mode in which the first type of detecting process is not performed.

Abstract: 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.

Abstract: An information management method collects log information of one or more home electrical apparatuses corresponding to service providers. Display screen data is generated which indicates a status of the log information. The display screen data includes groups of information which each contain information on an apparatus, a service provider corresponding to the apparatus, and log information output from the apparatus. Provision of the log information of each group is individually selectable. The display screen data is provided via a network to a display terminal that performs access to a server device. Information is received from the display terminal, which indicates that selection on whether or not provision of the log information is performed. Provision of the log information is stopped on the selected group when a determination is made that refusal of provision of the log information on the selected group is performed.

Abstract: A program execution device capable of protecting a program against unauthorized analysis and alteration is provided. The program execution device includes an execution unit, a first protection unit, and a second protection unit. The execution unit executes a first program and a second program, and is connected with an external device that is capable of controlling the execution. The first protection unit disconnects the execution unit from the external device while the execution unit is executing the first program. The second protection unit protects the first program while the execution unit is executing the second program.

Abstract: In a data distribution method according to the disclosure, first authentication servers and a first data server belong to a first group, and second authentication servers and a second data server belong to a second group different from the first group. A first authentication server obtains first transaction data that includes a data obtaining request indicating a request for obtaining or referring to data pertaining to an apparatus, and records a block including the first transaction data into its distributed ledger belonging to the first group. A second authentication server obtains the first transaction data, and records the block including the first transaction data into a distributed ledger belonging to the second group. The first authentication server causes the first data server to transfer the data pertaining to the apparatus held therein to the second data server or to make such data available for reference by the second data server.

Abstract: A fraud detecting method for use in an in-vehicle network system including a plurality of electronic control units that communicate with each other via a network includes detecting whether a state of a vehicle satisfies a first condition or a second condition, and switching, upon detecting that the state of the vehicle satisfies the first condition or the second condition, an operation mode of a second electronic control unit connected to the network. A first mode in which a first type of detecting process for detecting a fraudulent message in the network is performed is switched to a second mode in which the first type of detecting process is not performed upon detecting that the state of the vehicle satisfies the first condition. Moreover, the second mode is switched to the first mode upon detecting that the state of the vehicle satisfies the second condition.

Abstract: A method used in an on-board network system, having electronic controllers that exchange messages and a fraud-detecting electronic controller. The method includes receiving an inquiry for a vehicle status indicating whether a vehicle in which the fraud-detecting electronic controller is installed is running from an external device, transmitting the vehicle status to the external device, and determining whether a message transmitted conforms to fraud detection rules. The method also includes receiving from the external device the delivery data, including updated fraud detection rules and network type information indicating a network type that the updated fraud detection rules are to be applied The method further includes determining whether the vehicle is running, and whether the network type information indicates a drive network that is connected to an electronic controller related to travel of the vehicle. When the network type information does not indicate the drive network, updating the fraud detection rules.

Moreover, in the second mode, a second type of detecting process having a different degree to which a fraudulent message is detectible than the first type of detecting process is performed.
