摘要： Provided is a gateway device capable of reducing influence on intra-vehicle network communication from a cyber security attack that infringes availability represented by a DoS attack from an extra-vehicle network. Included are: an external-network-side transfer processing unit that transfers a communication frame received from an external network to an internal network; an internal-network-side transfer processing unit that transfers the communication frame transferred from the external network via the external-network-side transfer processing unit to the internal network; a transfer notification unit that gives a transfer notification to notify transfer of the communication frame from the external-network-side transfer processing unit to the internal-network-side transfer processing unit; and a monitoring unit that determines whether to transfer the communication frame based on at least one of a frequency of the transfer notification to the internal-network-side transfer processing unit and a transfer data amount of the communication frame transferred from the external-network-side transfer processing unit.

摘要： An arithmetic device includes a first core, a second core, and one or more other cores that perform arithmetic processing. The first core includes a first verification unit that performs a first verification process on a message received from outside of the arithmetic device. The second core includes a verification destination determination processing unit that determines whether or not the second core executes the second verification process on the message based on identification information included in the message.

摘要： Provided is a security processing device capable of preventing tampering of software related to detection and diagnosis of abnormality such as a security attack and taking a measure according to a cause in a case where the abnormality occurs. The security processing device which manages a device related to operation control of a vehicle includes: a control part which includes a non-secure area in which a mounted program is capable of being changed from an outside and a secure area in which a mounted program is incapable of being changed from the outside. The control part includes a code of an operation program which is mounted in the non-secure area and performs the operation control of the vehicle, and a diagnosis program which is mounted in the secure area and diagnoses abnormality of the code of the operation program and monitors communication with the outside. In a case where the abnormality of the operation program in the non-secure area is diagnosed, the diagnosis program in the secure area determines a type of the abnormality and executes processing on the basis of the determined type.
