Method for safe calculation of calculation result of cryptographic calculation, involves carrying out cryptographic calculation two times in data carrier |
| 摘要 |
<p>The method involves carrying out the cryptographic calculation two times in a data carrier (1). The meter reading of a charge meter (3) is incremented if the two calculation results do not agree after the comparison. The data carrier is blocked, once the meter reading reaches or exceeds a predetermined marginal meter reading. An independent claim is included for a data carrier with a microprocessor.</p> |
