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, wherein the first ID token is a paper-based and/or plastic-based document into which an electronic memory and an interface for the establishment of the connection to said first interface of said motor vehicle electronics device are integrated, wherein the first connection is a wireless connection,

a memory for storing a digital certificate issued to the motor vehicle electronics device,

wherein the motor vehicle electronics device is capable of cryptographically authenticating itself against the first ID token using the certificate, the authentication comprising;

transmitting the digital certificate to the first ID token; and

responding to a challenge received from the first ID token, the challenge dependent upon a public encryption key of the digital certificate and the response dependent upon a private encryption key corresponding to the public encryption key,

wherein the motor vehicle electronics device is capable of actuating at least one display apparatus for reproducing the data, and wherein data is read from the first ID token and the at least one display apparatus is actuated to reproduce the data only when the motor vehicle electronic device is authenticated; and

wherein said motor vehicle electronics device is constructed for establishing a second connection to a second ID token, the second ID token comprising an RFID chip card to be used as an electronic key, and wherein actuation of the at least one display apparatus for reproducing the data from the first ID token only occurs when the second connection can be established.

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, further comprising a second interface for storing the certificate in the memory, wherein the second interface is constructed to have contacts.

6. The motor vehicle electronics device as claimed in claim 1, further comprising a second interface for storing the certificate in the memory, wherein the second interface is constructed as a network interface, particularly as a mobile radio interface.

7. The motor vehicle electronics device as claimed in claim 6, wherein an identifier is stored in the motor vehicle electronics device and wherein the second interface is constructed for reading out the identifier.

8. The motor vehicle electronics device as claimed in claim 6, wherein the second connection is used for reading a key identifier from a second ID token and wherein a reference value for the key identifier is stored in the motor vehicle electronics device.

9. 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, wherein the display apparatus is not integrated with the motor vehicle electronics device.

10. 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.

11. The motor vehicle as claimed in claim 10, capable of establishing a secure data transmission channel between the motor vehicle electronics device and the at least one display apparatus, wherein the display apparatus is not integrated with the motor vehicle electronics device.

12. The motor vehicle electronics device as claimed in claim 1, wherein a root certificate is updated via the third connection.

13. The motor vehicle electronics device as claimed in claim 1, wherein the motor vehicle electronics device is constructed for establishing a third connection via the second interface, wherein the certificate is updated via the third connection, and wherein the third connection is a wired connection.

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, wherein the first ID token is a paper-based and/or plastic-based document into which an electronic memory and an interface for the establishment of the connection to said first interface of said motor vehicle electronics device are integrated,

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, the authentication comprising;

transmitting the certificate to the first ID token; and

responding to a challenge received from the first ID token, the challenge dependent upon a public key of the certificate and the response dependent upon a private key corresponding to the public key,

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

actuating the motor vehicle display apparatus for reproducing the data from the first ID token, wherein the at least one display apparatus is actuated for reproducing the data from the first ID token only when the authentication of the motor vehicle electronics device with respect to the first ID token has been carried out successfully and the second connection can be established; and

wherein said motor vehicle electronics device is constructed for establishing a second connection to a second ID token, the second ID token comprising an RFID chip card to be used as an electronic key, and wherein actuation of the at least one display apparatus for reproducing the data from the first ID token only occurs when the second connection can be established.

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 a second connection, between the motor vehicle electronics device and a second ID token, is used for reading out a key identifier from the second ID token, wherein the second token comprises an RFID chip card to be used as an electronic key and wherein a reference value for the key identifier is stored in the motor vehicle electronics device.

17. A non-transitory 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, wherein the first ID token is a paper-based and/or plastic-based document into which an electronic memory and an interface for the establishment of the connection to said first interface of said motor vehicle electronics device are integrated,

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, the authentication comprising;

transmitting the certificate to the first ID token; and
