METHOD FOR SECURING A PROGRAM

摘要

Disclosed is a method for securing a program, which can be operated on a terminal, against unauthorized use, wherein a key code is stored in a separate key element such that it is protected against unauthorized reading and wherein the key element is connected to the terminal prior to or during the use of the program via an interface and the stored key code is checked by means of a data transfer between the terminal and the key element and the program is run correctly only if the results of the check are positive. A subscriber identifier module is used as a key element in which the key code is stored in order to authenticate a mobile radio device of the user in relation to a mobile radio network. The invention also relates to a corresponding subscriber identification module.
