| description | The invention relates to a method for cryptographic authentication in access security systems. The aim of the invention is to provide a software solution. To this end, the method for secured storage of counter states in a non-volatile memory (EEPROM) involves an incrementing process, and the current counter state is updated in only one EEPROM segment following each incrementing process, a subsequent access to the EEPROM only being enabled in the event of a successful incrementing of an EEPROM-based counter. |
