Abstract: An encryption key distribution system includes: a key distribution ECU that transmits an encryption key; and a key reception ECU that receives the encryption key, the key distribution ECU: transmits the encryption key to the key reception ECU; and determines completion of transmission of the encryption key, based on a result of determination as to whether first verification data transmitted from the key reception ECU matches second verification data of the encryption key which is calculated from a common key stored in the key distribution ECU and an identifier of the key reception ECU, the key reception ECU: records the received encryption key in the key reception ECU; calculates the first verification data from the same common key as the common key stored in the key reception ECU and the identifier of the key reception ECU; and transmits the calculated first verification data to the key distribution ECU.

Abstract: A vehicle system includes a plurality of electronic control devices respectively includes a first processor configured to control each unit of a vehicle; and a management electronic control device that includes a second processor configured to manage the plurality of electronic control devices, wherein when an encryption key used to verify a message is updated to another encryption key, the second processor transmits a first message that includes a controller area network identifier (CAN-ID) that identifies the message and a second message that includes the another encryption key to a network, and when the CAN-ID of the message included in the first message is a CAN-ID to be processed, the first processor updates the encryption key used to verify the message to the another encryption key included in the second message.

Abstract: A computer of an image processing device executing an image processing program displays, on a display device, a virtual three-dimensional space where there are a plurality of objects. The computer varies a size of a collision detection region defined for a predetermined object so that the size repeatedly increases and decreases over time, while the predetermined object is moving. Then, based on the collision detection region, it is determined whether or not the predetermined object and another object are in contact with each other. The computer displays, on the display device, a predetermined effect being inflicted on the object determined to be in contact with the predetermined object.
