DEVICE FOR HANDLING PAPER MONEY AND/OR COINS AND METHOD FOR INITIALIZING AND OPERATING SUCH A DEVICE

摘要

The invention relates to a device (10) for handling paper money and/or coins, comprising a control unit (12), a peripheral device (16, 18, 20, 22, 24) connected to the control unit (12), and a hard disk (14) connected to the control unit (12), wherein the control unit (12): detects the peripheral device (16, 18, 20, 22, 24) connected to the control unit (12); generates a data encryption key (DEK); reads an identification information item (W) from the peripheral device (16, 18, 20, 22, 24), which unambiguously identifies the peripheral device (16, 18, 20, 22, 24); generates a key encryption key (KEK) on the basis of the read identification information (W); stores an encrypted data-encryption key (VDEK), which can be generated by encrypting the data encryption key (DEK) with the aid of the key encryption key (KEK), in a storage area of the hard disk (14), and determines the data encryption key (DEK) by decrypting the encrypted data-encryption key (VDEK) with the aid of the key encryption key (KEK), and wherein the control unit (12) encrypts, with the aid of the data encryption key (DEK), body data to be stored on the hard disk(14), or decrypts, with the aid of the data encryption key (DEK), encrypted body data stored on the hard disk.
