Abstract: A vehicle-function management device includes one or more processors and a storage medium storing a program. The program includes one or more instructions that cause the one or more processors to acquire certificate data including contents of a function's setting of a vehicle in a specific area and effective-distance information regarding a change of the function's setting, acquire positional information of the vehicle, determine a position of the vehicle by short-range wireless communication, change the function's setting in accordance with the contents of the function's setting in the certificate data when it is determined that the vehicle is in the specific area designated by the certificate data, and terminate a state in which the function's setting has been changed when a travel distance of the vehicle in a state in which the function's setting has been changed exceeds a travel distance indicated by the effective-distance information.

Abstract: A control system includes a first processor and a second processor. The first processor includes: first security circuitry configured to hold a first encryption key and permit limited access from an external device; and first storage circuitry. The second processor includes: second security circuitry configured to hold a second encryption key and permit limited access from the external device; and second storage circuitry. The first processor is configured to: generate an authentication key to be used for authentication processing; supply the authentication key to the second processor; generate a first authentication key by encrypting the authentication key using the first encryption key; and store the first authentication key in the first storage circuitry. The second processor is configured to: generate a second authentication key by encrypting the authentication key supplied from the first processor using the second encryption key; and store the second authentication key in the second storage circuitry.

Abstract: An information processing apparatus includes a processor(s) and a storage medium storing a program. The program causes the processor(s) to execute: a first reception process for receiving partial data in update data other than including a first software program and first version information indicating a version of the first software program and stored in an area closer to a head than the first software program; a process for storing the partial data in a first storage area; a process for comparing the first version information and second version information indicating a version of a pre-update second software program stored in a second storage area for the first software program; and a process for storing, in the second storage area, the first software program received by a second reception process subsequent to the first reception process when the first version information is determined to be newer than the second version information.

Abstract: A control apparatus for a vehicle includes a processor, a storage, and a first determining unit. The processor is configured to control a control target mounted in the vehicle. The storage is configured to contain unauthorized entry data. The unauthorized entry data indicates a presence of an unauthorized entry into the vehicle. The first determining unit is configured to make a determination on a necessity of a secure boot process upon activation of the processor, on the basis of the unauthorized entry data.

Abstract: A vehicle detection information sharing system includes a detection information acquiring unit, a vehicle information acquiring unit, a risk degree calculator, and an information transmitter. The detection information acquiring unit is configured to acquire detection information on an obstacle detected by a first vehicle traveling on a road. The vehicle information acquiring unit is configured to acquire vehicle information on a second vehicle traveling on the road. The risk degree calculator is configured to calculate a risk degree on the basis of the detection information and the vehicle information. The risk degree is a degree of risk that arises between the second vehicle and the obstacle. The information transmitter is configured to transmit, to the second vehicle, risk avoidance information corresponding to the risk degree.

Abstract: An electronic control unit to be applied to a vehicle includes at least one electronic control unit. The at least one electronic control unit is configured to: store a public key; receive a role list to set a specific work permitted to be executed by the at least one electronic control unit from a communication apparatus; perform signature verification of the role list using the public key; set, based on the role list verified by the signature verification, an available work list indicating the specific work permitted to be executed; and execute, when receiving a request message requesting the specific work set in the available work list, a process of the specific work.

Abstract: A vehicle communication processor includes a communication control unit that receives digitally signed information from an external device, and a first control processing unit and a second control processing unit that process information received by the communication control unit. The communication control unit or the first control processing unit includes a sign verification section that performs an authenticity verification of a digital sign of the digitally signed information. The second control processing unit includes an execution preparation section and an execution determination section. The execution preparation section performs an execution preparation process on data of the digitally signed information in parallel to the authenticity verification on the digital sign. The execution determination section determines whether the data of the digitally signed information is to be executed in a case where the digital sign of the digitally signed information is verified as being authentic.

Abstract: An external communication system for a vehicle includes communication devices and a controller. The communication devices are provided in the vehicle. The communication devices are configured to transmit and receive communication data between a server device and the vehicle via mutually different communication paths. The controller is configured to control communication by the communication devices. The communication devices include a first communication device and an inter-vehicle communication device. When the inter-vehicle communication device is requested, from another vehicle, to acquire communication data between the another vehicle and the server device, the controller transmits communication data received by the first communication device from the server device, from the inter-vehicle communication device to the another vehicle, and transmits communication data received by the inter-vehicle communication device from the another vehicle, from the first communication device to the server device.

Abstract: An external communication system for a vehicle includes multiple communication devices and a controller. The multiple communication devices are provided in the vehicle. The communication devices transmit and receive communication data between a server device and the vehicle via mutually different communication paths. The controller is control communication by the multiple communication devices. The controller sets at least one of the multiple communication devices as a main communication device that transmits and receives the communication data between the server device and the vehicle. The controller sets at least one of the remaining communication devices as a backup communication device that transmits and receives the communication data between the server device and the vehicle.
