Abstract

A maintenance system includes a server device, a terminal device, and an in-vehicle device installed in a vehicle. The server device includes a worker authentication information reception unit configured to receive worker authentication information from the terminal device, a server authentication processing unit configured to perform an authentication process on the worker authentication information, and a server key transmission unit configured to transmit a first key to be used with the in-vehicle device to the terminal device whose worker authentication information has been successfully authenticated by the server authentication processing unit. The terminal device includes a worker authentication information transmission unit configured to transmit the worker authentication information to the server device, a terminal key reception unit configured to receive the first key from the server device, and a terminal authentication processing unit configured to perform an authentication process with the in-vehicle device using the first key.
