Abstract
A relay device mounted to a vehicle includes a plurality of function units. The relay device includes: an authentication processing unit configured to acquire authentication information of a function unit from an external device outside the vehicle, and perform an authentication process regarding the function unit by using the acquired authentication information; and a relay processing unit configured to, on the basis of a result of the authentication process performed by the authentication processing unit, relay information between the function unit and another function unit. When a validity time limit of the authentication information has expired, the authentication processing unit acquires, from the external device, the authentication information that is new.
