1. Data transfer system for programming motor vehicle control devices comprising:

  • a first data-processing device (5) which is adapted to store data which is to be protected against unauthorized access;

    a second data-processing device (9); and

    ,a third data-processing device (12), which is adapted to receive data which is to be protected against unauthorized access and is to be transferred to the first data-processing device (3, 5);

    wherein the first data-processing device (5) and the second data-processing device (9) are adapted to be connected to one another via a first data transfer device and for data stored in the first data-processing device (5) to be transferred as first transfer data to the second data-processing device (9),wherein the second data-processing device (9) and the third data-processing device (12) are adapted to bring the second data-processing device (9) from an area at the first data-processing device (5) into a spatial area in which the second data-processing device (9) can be connected to the third data-processing device (12) indirectly or directly via a second data transfer device (11), to connect the second data-processing device (9) and the third data-processing device (12) indirectly or directly via the second data transfer device (11) and transfer at least a part of the first transfer data from the second data-processing device (9) to the third data-processing device (12) as second transfer data;

    wherein the third data-processing device (12) is adapted to generate an authentication response value from the first transfer data or a part thereof by means of a generating function;

    wherein the second data-processing device (9) and the third data-processing device (12) are adapted to transfer the authentication response value and data stored in the third data-processing device (12) as third transfer data to the second data-processing device (9);

    wherein the first data-processing device (5) and the second data-processing device (9) are adapted to transfer the authentication response value and the other third transfer data or part thereof to the first data-processing device (5) as fourth transfer data; and

    wherein the first data-processing device (5) is adapted to check the correctness of the authentication value by means of the first transfer data or parts thereof and to process the fourth transfer data further.
