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-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.
