METHOD FOR SECURELY STORING DATA IN A MEMORY OF A PORTABLE DATA CARRIER

摘要

The present invention relates to a method of storing the secure data to the multi-level memory of the portable data carrier. The multi-level memory includes at least three levels (E, NE) which can take each of the one or more multi-level memory cells (SZ). At least three-level denotes a different data content, that is defined with respect to the respective level (E, NE) is valid or invalid of the memory cell (SZ). Level (E, NE) of the memory cells (SZ) are selectively defined as valid or invalid depending on the required security level. ;
