摘要： The invention relates to a data carrier (1) having a semiconductor chip (5). In order to prevent an attacker from determining secret data of the chip (5) from intercepted signal patterns of the chip (5), security-relevant operations are performed only with commands or command strings of the operating program whose use does not permit the processed data to be inferred from the signal patterns.

摘要： The invention relates to a data carrier having a semiconductor chip (5) with at least one memory. The memory contains an operating program that is able to perform at least one operation (h). In order to prevent unauthorized access to the data (x) processed with the operation (h), both said data and the operation (h) itself are disguised. The disguising of the data (x) and the operation (h) is coordinated such that the disguised operation (hR1R, hR1R2) generates either the output data (y) of the undisguised operation (h) or disguised output data (y{circle around (x)}R2) from which the output data (y) can be determined.

摘要： The invention relates to a data storage medium having a semiconductor chip which has at least one memory in which an operating program is stored which contains a number of commands, with each command producing signals which can be detected from outside the semiconductor chip.According to the invention the data storage medium is designed in order to split secret data, which is stored in the semiconductor chip in order to carry out security-relevant or safety-relevant operations or is generated by this semiconductor chip, into at least three data parts, with an arithmetic unit being included in order to calculate a random number and in order to divide the random number, with the first data part being the integer result of the division process, the second part being the remainder of the division process, and the third part being the random number itself.

摘要： 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 (14). 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.
