Abstract

A method for operating a mobile device, not assigned to a motor vehicle, via an electronic device with a display and operator control device of the motor vehicle is made available. The program has program parts for a user interface and for operator control sequences which are assigned a digital certificate. The user interface comprises fixed areas for displaying variable contents. The program parts are transmitted together with the digital certificate to the electronic device of the motor vehicle and are carried out when the certificate is successfully checked. The transmission of data without protection by a digital certificate is restricted to the variable contents for display in the fixed areas of the user interface.

Claims

1. A method for displaying information and/or operating a mobile device not assigned to a motor vehicle via an electronic unit with a display and operating device of a motor vehicle, the method comprising:

storing a program that is executable on the mobile device and comprises program parts for a user interface and for operating processes of the program, the user interface having fixed areas for displaying variable contents;

storing a digital certificate, which is assigned to the program parts for the user interface and for the operating processes of the program executable on the mobile device;

transmitting the program parts for the user interface and for the operating processes with the associated certificate from the mobile device to the electronic unit of the motor vehicle;

verifying the transmitted digital certificate in the electronic unit of the motor vehicle;

executing the program parts transmitted from the mobile device subject to the verification of the transmitted digital certificate; and

displaying the variable contents in the fixed areas of the user interface.

2. The method according to claim 1, wherein the digital certificate is issued beforehand by a certification server, wherein the digital certificate is assigned to the program parts for the user interface and for the operating processes via the certification server.

3. The method according to claim 2, wherein the certification server for the certification of the contents has at least one key pair in each case comprising a private key and a public key, wherein the at least one public key is used for verification in the electronic unit of the motor vehicle, wherein the at least one public key is stored in the electronic unit of the motor vehicle or is transmitted to the electronic unit of the motor vehicle from the certification server or some other trusted source over a secure data connection.

4. The method according to claim 3, wherein the digital certificate comprises a digital fingerprint, and wherein the digital fingerprint is created by the certification server via the private key from the program parts for the user interface and for the operating processes of the program executable on the mobile device.

5. The method according to claim 4, wherein the certification server issues the certificate in accordance with the ITU-T standard X.509.

6. The method according to claim 2, wherein the program executable on the mobile device and the digital certificate assigned to the program parts for the user interface and for the operating processes of the program executable on the mobile device are transmitted from the certification server.

7. The method according to claim 1, wherein the variable contents of the mobile device are transmitted to the electronic unit of the motor vehicle.

8. The method according to claim 1, wherein the electronic unit of the motor vehicle is connected to at least one data bus system of the motor vehicle and the variable contents are obtained from data from the at least one data bus system.

9. The method according to claim 8, wherein the data obtained from the at least one bus system are transmitted from the electronic unit of the motor vehicle to the mobile device for processing by the program executable on the mobile device and the processed data are transmitted from the mobile device to the electronic unit of the motor vehicle.

10. The method according to claim 1, wherein at least one command generated via the operating device is transmitted to the mobile device.

11. The method according to claim 10, wherein the program executable on the mobile device is controlled as a function of the at least one command.
