Abstract:
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.
