Abstract: An apparatus for controlling an automatic unlocking and/or locking of a vehicle is described, which is automatically effected by a key device located in an environment of the vehicle. The apparatus is configured to detect at least one superfluous unlocking and locking cycle, in which the vehicle is automatically unlocked due to the entry of the key device into a predefined spatial area around the vehicle, and is automatically locked again due to a subsequent removal of the key device, without a door and/or flap of the vehicle having been opened in between. The apparatus is further configured to adapt, in particular to reduce, the spatial area for the automatic unlocking and/or locking of the vehicle in response to the detection.

The method further includes obtaining information about one or more personalized settings or services of the user for the vehicle based on the user grant information, and applying the one or more settings to the vehicle or enabling the one or more services for the user in the vehicle.

Abstract: A method for controlling a security function of a motor vehicle includes the steps of making a communication connection between the motor vehicle and a mobile device via Bluetooth Low Energy Long Range; determining a distance between the motor vehicle and the mobile device via channel sounding on the communication connection; and changing the communication connection to Bluetooth Low Energy Normal Mode when the distance is below a predetermined threshold.

Abstract: A device for identification of an owner includes an interface and a control module. The interface is configured to communicate with a user terminal. The control module is configured to control the interface. The control module is further configured to receive information about an intended identification of the user terminal. The control module is also configured to generate signed information based on the information about an intended identification, wherein the signed information can be used for identification of the owner, and send the signed information to the user terminal.

Abstract: A vehicle is disclosed herein having a network device for providing Bluetooth encryption data. The network device comprises a controller and one or more interfaces for communication with a user terminal. The controller is configured to receive information for generating Bluetooth encryption data for establishing an encrypted Bluetooth connection between the vehicle and a user terminal based on the received information. The controller is further configured to generate the Bluetooth encryption data, and synchronize the Bluetooth encryption data between the vehicle and the user terminal.

Abstract: A digital key provides security for use of a motor vehicle. A method for delivering a digital key such as this from a sender to a recipient includes steps of a secret of the sender being deposited with a manufacturer service; a key created by the recipient being signed by the sender; the signed key being relayed to the recipient; an input for the secret by the recipient being acquired; the key and the input being relayed from the recipient to a tracking service; the input being relayed from the tracking service to the manufacturer service; the manufacturer service determining that the input and the secret match; a consent being relayed from the manufacturer service to the tracking service; and an attestation being relayed from the tracking service to the recipient.

Abstract: A vehicle is disclosed herein including a plurality of antennas for communicating via ultra-wideband (UWB) and a controller for evaluating a UWB signal of a transceiver, which is received by means of the plurality of antennas. The plurality of antennas include a first subset of one or more antennas and a second subset of one or more antennas. The controller is configured to determine a receiving direction of the signal in a first plane based on signal components of the signal received by means of the antennas of the first subset, and determine a receiving direction of the signal in a second plane based on signal components of the signal received by means of the antennas of the second subset, wherein the first plane is aligned perpendicularly to the second plane. The controller is further configured to determine a position of the transceiver relative to the vehicle based on the receiving direction of the signal in the first plane and based on a receiving direction of the signal in the second plane.

Abstract: A method for controlling access to a motor vehicle includes steps of creating a digital key for access to the motor vehicle on the part of a friend device; signing the created key by an owner device of the motor vehicle; transmitting a tracking request for the signed key to a tracking service; transmitting a tracking response from the tracking service to the friend device; wherein the tracking response comprises encrypted information of the tracking service; and presenting the encrypted information to the motor vehicle by the friend device. In this case, the tracking response comprises additional information that the tracking service has obtained from a manufacturer service in relation to the tracking request.

Abstract: An apparatus for controlling a motor vehicle includes: a wireless interface for communicating with an external device; a memory in which a public digital key of the device is stored; an interface to a control apparatus of the motor vehicle; and a processing device. The processing device is configured to detect a request from the device for one-sided authentication; to perform a method for authenticating the device to the motor vehicle on the basis of the stored digital key; and to activate the control apparatus if the authentication is successful.

Abstract: An apparatus for controlling a motor vehicle includes a wireless interface for communicating with an external device; a memory in which a public digital key of the device is stored; an interface to a control apparatus of the motor vehicle; and a processing device. The processing device is configured to determine a lack of availability of a security device configured to perform a two-sided authentication with the external device; to perform an authentication of the device to the motor vehicle on the basis of the stored digital key; and to activate the control apparatus if the authentication is successful.

Abstract: Embodiments relate to a method for accessing a functionality of a vehicle via a mobile device. The method includes sending, using a first radio access technology, RAT, a ranging intent message from the mobile device to the vehicle; initiating, by the vehicle and using a second RAT, a ranging session for localizing the mobile device upon receipt of the ranging intent message; and upon initiating the ranging session, sending a ranging response message from the vehicle to the mobile device using the first RAT, the ranging response message indicating whether the mobile device is inside or outside at least one operational localization range of the vehicle.

Abstract: A method and apparatus are used for a vehicle and for communicating with a personal communications device. The method includes establishing a secured communication link between the vehicle and the personal communications device for a first operation of accessing and/or starting the vehicle. The method further includes reusing the secured communication link for an application of the vehicle additional to the first operation.

Abstract: Methods and apparatuses for secure communication between a first and a second communication partner are provided. The method for secure communication between a first and a second communication partner comprises establishing a communication link between the first and the second communication partner. Further, the method comprises determining one or more session identifiers by one of the first and the second communication partner. The method additionally comprises communicating the one or more session identifiers to the other of the first and the second communication partner. The method comprises determining, for each of the one or more session identifiers, a respective symmetric session key in each of the first and the second communication partner. In addition, the method comprises storing the one or more session identifiers and the corresponding symmetric session keys in each of the first and the second communication partner for one or more subsequent secure communication sessions.
