Abstract
In a method for reading initialization data (IND) into a chip card, the chip card receives an encrypted authentication value (EAV) and decrypts it to obtain at least one release key (ENK). The release key (ENK) is checked for a match with a release key (ENK') stored on the chip card (). If there is a match, the initialization data (EIND, IND) are received and written to a nonvolatile memory of the chip card. A method for generating a record for initializing a chip card. a chip card and a computer-readable data carrier have corresponding features. The invention is provided in particular for initialization of chip cards by external partners of the chip card manufacturer, whereby as few possibilities of attack as possible are to be offered.
