<p>The invention relates to a method for enabling a first chip card (116) for use with a data processing system (100) with the aid of a second chip card (126), wherein the data processing system has means (110) for generating an integrity assessment code from predetermined data which are stored in the data processing system, said method having the following steps: - the first chip card requests (162) an enable signal (152) from the second chip card, - the integrity assessment code is requested (164) from the means (110) for generating an integrity assessment code, - the second chip card decrypts (156) a signature (118) which is associated with the data processing system, - the second chip card compares (158) the decrypted signature with the integrity assessment code, - the enable signal is generated if the decrypted signature and the integrity assessment code match, - the first chip card is enabled after the first chip card has received the enable signal.</p> |
