A system for managing an authorization for a vehicle includes a vehicle-based memory module, and a communication module. The memory module includes a key list containing a multiplicity of entries for a multiplicity of digital keys, which can be allocated to individual users via a first electronic apparatus. Each digital key represents a vehicle authorization for a user, and each entry in the key list is assigned a unique identifier. The communication module is configured to transfer from the vehicle to the first electronic apparatus at least one identifier assigned to an unallocated entry in the key list.

System and method for managing an authorization for a vehicle

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.
