  • Method and arrangement for configuring electronic devices
    Patent number: 8880859
    Abstract: The invention relates to a method for configuring electronic devices, particularly terminals, wherein during configuration at least parts of first configuration data on a chip card are fed to an electronic device, wherein the configuration data are stored on the chip card as second configuration data such that the stored data are the result of an obfuscation following at least one first algorithm. Furthermore, at least parts of the first algorithm can be derived by the electronic device. The stored second configuration data are subjected to a de-obfuscation by the device such that, having knowledge of the first algorithm, they can be reconstructed as first configuration data and the configuration of the terminal can be based thereon. The invention further relates to an arrangement having means for carrying out the method.
