Abstract
The present invention prevents a maintenance tool for carrying out maintenance work of an electronic control unit (ECU) from being abused by a third person. In an authentication system according to the present invention, an authentication apparatus authenticates an operator of an operation terminal (equivalent to the maintenance tool), and the operation terminal forwards an authentication code generated by the authentication apparatus to the ECU. By using the authentication code, the ECU determines whether or not to permit the operation terminal to carry out a maintenance operation.
