1. A method for identifying and verifying control software of a rail vehicle, wherein the control software is formed by functions, wherein each function of the functions performs a task respectively assigned thereto, in which the functions, in their interconnected entirety, form a structure of the control software, which comprises the steps of:
creating a function-dependent checksum for each of the functions resulting in a plurality of function-dependent checksums;
creating a structure-dependent checksum for the structure; and
creating an overall checksum for the control software from the function-dependent checksums and from the structure-dependent checksum, wherein the overall checksum identifies and verifies the control software for authorization in a country.
