Apparatus for handling bills and/or coins, and method for initializing and operating such an apparatus

摘要

An apparatus (10) for handling bills and/or coins has a control unit (12) that detects a peripheral device connected to the control unit (12), generates a data encryption key (DEK), reads from the peripheral device identification information (W) that denotes the peripheral device, generates a key encryption key (KEK) based the read identification information (W), stores an encrypted data encryption key (VDEK) generated by encrypting the data encryption key (DEK) using the key encryption key (KEK) in a memory area of a hard disk (14), and ascertains the data encryption key (DEK) by decrypting the encrypted data encryption key (VDEK) using the key encryption key (KEK). The control unit (12) encrypts useful data to be stored on the hard disk (14) in encrypted form using the data encryption key (DEK) or decrypts useful data stored on the hard disk in encrypted form using the data encryption key (DEK).

1. An apparatus for handling bills and/or coins, comprising:
a control unit; a plurality of peripheral devices connected to the control unit; a hard disk connected to the control unit; and a data encryption key configured for encrypting useful data to be stored on the hard disk; wherein the control unit is configured to:
detect the peripheral devices,read from each of the peripheral devices a respective piece of identification information that explicitly denotes the respective peripheral device,generate for the peripheral devices a respective key encryption key on the basis of the read pieces of identification information,store encrypted data encryption keys that can be generated by encrypting the data encryption key using the respective key encryption key, in a memory area of the hard disk,ascertain the data encryption key by decrypting the encrypted data encryption keys using the respective key encryption key, andencrypt useful data to be stored on the hard disk in encrypted form using the data encryption key or decrypt useful data that are stored on the hard disk in encrypted form using the data encryption keypermit access to the encrypted useful data that are stored on the hard disk only when the data encryption key can be ascertained from a preset minimum number of encrypted data encryption keys, the minimum number being at least equal to 2 and less than the number of stored encrypted data encryption keys.
