Abstract
A method of authenticating a controller by a gateway in a vehicle may include transmitting a first symmetric key to the controller; generating a first one-time authentication value (OTAV), encrypting the first OTAV with the first symmetric key and delivering the encrypted first OTAV to the controller; sending a request for authentication using the first OTAV to the controller; and receiving a hash value from the controller in response to the request.
