A digital computing device controlling the access to encrypted digital information includes a control unit, peripheral devices connected to the control unit, a hard disk connected to the control unit storing the digital data, and a data encryption key configured for encrypting the digital data. The control unit is configured to detect the peripheral devices, read identification information from the peripheral devices that denotes the respective peripheral device, generate for the peripheral devices a respective key encryption key on the basis of the read identification information, initially store at least one encrypted data encryption key that is generated by encrypting the data encryption key using the respective key encryption key, in a memory area of the hard disk, and after the initial storage determine the data encryption key by decrypting the encrypted data encryption key using the respective key encryption key derived from the respective identification information.
