Abstract

The invention relates to a motor vehicle electronics device comprising a first interface (116) for establishing a first connection to a first ID token (134) in order to read data from the first ID token, a memory (104) for storing a certificate, means (122) for the cryptographic authentication with respect to the first ID token using the certificate, means (130) for actuating at least one display apparatus (136, 138) for reproducing the data, and a second interface (118) for storing the certificate in the memory.

Claims

1. A motor vehicle electronics device comprising

a first interface for establishing a first connection to a first ID token in order to read data from the first ID token,

a memory for storing a certificate,

wherein the motor vehicle electronics device is capable of cryptographically authenticating the first ID token using the certificate,

wherein the motor vehicle electronics device is capable of actuating at least one display apparatus for reproducing the data,

a second interface for storing the certificate in the memory.

2. The motor vehicle electronics device as claimed in claim 1, wherein the data contain a motor vehicle license number.

3. The motor vehicle electronics device as claimed in claim 1, wherein the first interface is constructed to be contactless.

4. The motor vehicle electronics device as claimed in claim 3, wherein the first interface is constructed as a radio interface.

5. The motor vehicle electronics device as claimed in claim 1, wherein the second interface is constructed to have contacts.

6. The motor vehicle electronics device as claimed in claim 5, wherein the second interface is constructed for connection of a cable.

7. The motor vehicle electronics device as claimed in claim 1, wherein the second interface is constructed as a network interface, particularly as a mobile radio interface.

8. The motor vehicle electronics device as claimed in claim 1, wherein an identifier is stored in the motor vehicle electronics device and wherein the second interface is constructed for reading out the identifier.

9. The motor vehicle electronics device as claimed in claim 1, wherein the motor vehicle electronics device is constructed for establishing a second connection to a second ID token, wherein the actuation of the at least one display apparatus for reproducing the data only occurs when the second connection can be established.

10. The motor vehicle electronics device as claimed in claim 9, wherein the second connection is used for reading a key identifier from the second ID token and wherein a reference value for the key identifier is stored in the motor vehicle electronics device.

11. The motor vehicle electronics device as claimed in claim 1, additionally capable of establishing a secure data transmission channel for actuating the at least one display apparatus.

12. A motor vehicle comprising a motor vehicle electronics device as claimed in claim 1 and comprising at least one display apparatus which is constructed for actuation by the motor vehicle electronics device.

13. The motor vehicle as claimed in claim 12 capable of establishing a secure data transmission channel between the motor vehicle electronics device and the at least one display apparatus.

14. A method for displaying data on a motor vehicle display apparatus comprising the following steps:

establishing a first connection between a motor vehicle electronics device and a first ID token,

accessing a memory of the motor vehicle electronics device for reading a certificate,

cryptographically authenticating the motor vehicle electronics device with respect to the first ID token by using the certificate,

reading out data from the first ID token via the first connection after the authentication of the motor vehicle electronics device with respect to the first ID token has been carried out successfully,

actuating the motor vehicle display apparatus for reproducing the data.

15. The method as claimed in claim 14, wherein a third connection, via which the certificate and/or a root certificate is updated, is established via a second interface of the motor vehicle electronics device.

16. The method as claimed in claim 14, wherein the motor vehicle electronics device is constructed for establishing a second connection to a second ID token, wherein the at least one display apparatus is actuated for reproducing the data only if the second connection can be established.

17. The method as claimed in claim 16, wherein the second connection is used for reading out a key identifier from the second ID token and wherein a reference value for the key identifier is stored in the motor vehicle electronics device.

18. A tangible computer readable medium comprising program instructions, the instructions executed by a motor vehicle electronics device and comprising the following steps:

establishing a first connection between a motor vehicle electronics device and a first ID token,

accessing a memory of the motor vehicle electronics device for reading a certificate,

cryptographically authenticating the motor vehicle electronics device with respect to the first ID token by using the certificate,

reading out data from the first ID token via the first connection after the authentication of the motor vehicle electronics device with respect to the first ID token has been carried out successfully,

actuating the motor vehicle display apparatus for reproducing the data.

19. The method as claimed in claim 18, wherein a third connection, via which the certificate and/or a root certificate is updated, is established via a second interface of the motor vehicle electronics device.

20. The method as claimed in claim 18, wherein the motor vehicle electronics device is constructed for establishing a second connection to a second ID token, wherein the at least one display apparatus is actuated for reproducing the data only if the second connection can be established.
