Abstract: A method is provided for generating a soft token by which attributes of a user may be authenticated. A request to generate the soft token is transmitted from an electronic device of the user to a service provider computer via a first secure connection. After receiving the request, the service computer generates a one-time password, records the password as a session identifier, and transmits the password to the electronic device. The password is output by the electronic device via a user interface. The user enters the password into a user computer system, from where it is transmitted, via a second secure connection, to the service computer system. If the recorded password agrees with the received password, one or more attributes are read from an ID token of the user and a corresponding soft token is generated and transmitted to the electronic device or user computer system.

Abstract: A communications system for a motor vehicle in which the hands-free device for a mobile phone is integrated into an audio or information system of the motor vehicle such as a car radio. The voice and/or data transmission between the mobile phone and the hands-free device takes place over an additional short-range radio link. A transceiver for this short-range radio link is contained both in the car radio and in the mobile phone. The need to install additional connection interfaces is thus eliminated. In addition, the need to couple the mobile phone to the hands-free device using a cable is eliminated. This has the advantage that the mobile phone can remain, for example, in the driver's pocket. The coupling between the mobile phone and car radio occurs automatically if the mobile phone moves into the range of the short-range radio link of the car radio.
