Abstract: The invention relates to a method (100) for securing a communication between a mobile communication apparatus (10) and a vehicle (5), in particular for authentication at a passive access system of the vehicle (5), wherein the vehicle (5) comprises at least one radio unit (20).

Abstract: A method for delegating access rights to a secured object includes generating a first-order data packet in a trusted central management device. The data packet contains a first identifier, a first data set having access rights to a secured device and a first data secret key for encryption and signature. A second-order data packet is signed via the first data secret key and is created in the first mobile communication device and contains a unique identifier, reference data, a second data set having access rights, a second data secret key for encryption and a first data container. The first data container is encrypted via the first data secret key and contains the first identifier and the second data secret key. The signed second-order data packet is transmitted to a second mobile communication device of a second user.

Abstract: A method of car access includes receiving a localization secret at data processing hardware. The localization secret defines a portion of vehicle authentication information for a vehicle. The method also includes receiving at least one localization frame from a mobile device at the data processing hardware. The at least one localization frame includes identification information for the mobile device. The method further includes determining, by the data processing hardware, whether the at least one localization frame includes a derived localization secret. The derived localization is defined by the localization secret. The method further includes, when the at least one localization frame includes the derived localization secret, supplying, by the data processing hardware, power to a vehicle control module of the vehicle and authentication information to the vehicle control module of the vehicle.
