Abstract
A motor vehicle stores a first one-way hash of a password and an encrypted value from a second one-way hash of the password. A method for authenticating a device with respect to the vehicle includes the following: a PACE procedure is carried out so that the device and the motor vehicle determine the same session key; the motor vehicle generates a communication key on the basis of the session key and the encrypted one-way hash; and the device generates the communication key based on the session key and the second one-way hash.
