Abstract: An anomaly detection server is provided. The anomaly detection server is a server for counteracting an anomalous frame transmitted on an on-board network of a single vehicle. The anomaly detection server acquires information about multiple frames received on one or multiple on-board networks of one or multiple vehicles, including the single vehicle. The anomaly detection server, acting as an assessment unit that, based on the information about the multiple frames and information about a frame received on the on-board network of the single vehicle after the acquisition of the information about the multiple frames, assesses an anomaly level of the frame received on the on-board network of the single vehicle.

Abstract: A controller and a first device perform mutual authentication, create a group key, and share the group key, and the first device is set as a reference device. Thereafter, at a group key update timing when the controller and the reference device update the group key to an updated group key, the controller and a second device, which is not the reference device, perform mutual authentication, and the updated group key is also shared by the second device. Further, encrypted data is generated by encrypting transmission data by using the group key, a MAC (Message Authentication Code) is generated from the transmission data, a header, a transmission source address, and a transmission destination address, and a message that includes the encrypted data, the header, the transmission source address, the transmission destination address, and the MAC is broadcast.

Abstract: 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 via the bus and verifies the message authentication code in accordance with the identifier included in the at least one data frame.

Abstract: A hub is connected to first and second networks where first-type and second-type frames are transmitted following first and second communication protocols. The hub sequentially receives each of the first-type and second-type frames, and stores data in first and second reception buffers. If the destination of data stored in the first and second reception buffers is the first network, the hub stores the data in a first transmission buffer. If the destination is the second network, the hub stores the data in a second transmission buffer. If the first transmission buffer is a priority transmission buffer, the hub transmits first yet-to-be-transmitted data in the first transmission buffer with priority. If the second transmission buffer is the priority transmission buffer, the hub transmits second yet-to-be-transmitted data in the second transmission buffer with priority.

Abstract: An unauthorized activity detection method is provided in an onboard network system having multiple electronic units (ECU) that perform communication via a bus, such that an occurrence of an unauthorized state can be detected by monitoring frames transmitted over the bus. The unauthorized activity detection method determines, by a monitoring electronic control unit using unauthorized activity detection rule information indicating a first condition, whether or not a set of frames received from the bus satisfies the first condition. The first condition being a condition regarding a relation in content between a first frame having a first identifier and a second frame having a second identifier that differs from the first identifier. And the method further detects the occurrence of the unauthorized state in a case where the first condition is not satisfied.
